All Nailor fan powered terminal units are currentlyequipped with single speed, direct drive, fractionalhorsepower, high efficiency, psc motors as standard.These motors are manufactured to specificationsdeveloped by Nailor specifically for the fan poweredterminal unit market. Some of the more important featuresare listed and explained below.

Motors not only provide power, but act as transformersand generators. Under certain conditions, this causesthe unused speed taps in multiple speed motors to havelarge potential or static charges present. While thesecharges are not doing any work, they will createdamage to the windings if their potential voltages aregreater than the winding insulating quality. This is oftenthe case and lifetimes are shortened. Nailor fanpowered terminal units do not suffer from this malady.All motors are single speed.

Nailor motors are designed to operate at rotationalspeeds lower than those of our competitors. Thisrequires special stator wire sizing, special capacitorsizing and special bearings. These items are covered inour specifications. This assures you of high endperformance equal to or better than any of ourcompetitors and low end ranges below any of ourcompetitors.

Low end performance is often ignored. Many times, thisis because the range is not great enough to allow muchdifference, or because the low end performance isachieved by artificial means such as manual dampers tolower the airflows. Manual dampers lower airflows, butthey increase rpm. Increased rpm put back all the noisegeneration in the fan powered terminal unit as if it werestill operating at full airflow. This is due to the noisecaused by tip speed and vibration within the unit. Highrpm, regardless of airflow, will generate high noise.

Nailor solves this problem through low rpm for lowairflows. Typically, the motors in Nailor fan poweredterminal units can rotate as low as 350 rpm at low end,shedding as many as 14 to 20 decibels in the secondand third octave bands depending on which unit is beingselected. This means real sound level selections, unitsthat can produce NC's of 30 and 35 when appliedcorrectly and wider operating ranges on individual unitsfor greater flexibility in the zone.

Nailor fan powered terminal units are equipped withpermanently lubricated motors. The motors areequipped with oilers, but the oilers are not necessary aslong as the units are operated in typical ambienttemperature conditions. The specifications call for theoil reservoirs to have at least 50% of the original oil stillin the reservoir after 50,000 hours of use under normalconditions.

All Nailor fan powered terminal units have PSC motors.The capacitors are sized to provide ample startingtorque, even when turned down to the low minimumsallowed on Nailor fan powered terminal units.

All Nailor PSC motors are the highest efficiencyavailable in the market today. This too, is controlled bythe Nailor motor specifications. Higher efficiency meanslower operating expenses.

Nailor designed its own solid state fan speed controllers.They are designed to operate with the specific motor andblower combinations as used in Nailor fan poweredterminal units. They provide smooth and infiniteadjustment of motor speed from maximum to the lowestpreset low end limits found in the industry.

The speed controllers are largely responsible for theoperating ranges of the motors. High quality standardsallow very accurate low end stops. This assures Nailorcustomers of sound levels and performance as cataloged.

The matching of the motors and speed controllers allowsNailor fan powered terminal units lower watt consumptionas motor rpms are reduced. High efficiency is maintainedfrom high end performance to low end performance. Veryfew of our competitors can make a similar claim.

In addition to those items listed above, Nailor holds downnoise levels in the occupied space with heavy gaugemetal casings, dual density insulation and multipleisolation points between motors and casings. Nailor is asquiet as any and far quieter than most of our competitorswhen controlling similar airflows on competitiveequipment. Check out the sound data in this catalog.Notice there is no fine print covering the conditions underwhich the data does not apply. Notice that the minimumstatic requirement on series fan powered terminal units is0.05" w.g. (12 Pa). Then notice the correspondingly lowinlet static pressures on the parallel units. Notice thatNailor sound data is AHRI certified and independentlycertified by Energistics Laboratory, Houston. Comparethat to the competition.

Fan Powered Terminal Units are an economical means ofboth cooling and periodically heating the perimeter zonesof a building utilizing a single duct control system. Inaddition to inherent VAV economies, fan terminals utilizethe free heat derived from lighting, people and otherequipment and induce this warmer plenum air from thebuilding core ceiling plenum space and re-circulate it torooms calling for heating. If additional heating is required,optional supplementary heating coils may be activated.The need for a central source of warm air is eliminated.

During weekend or night-time operation, the central fansmay be turned off. Heat, if required, may be provided bythe terminal unit fan itself.

Fan Powered Terminal Units are the most popular designfor office buildings because they provide performancebenefits by way of lower first cost, (such as reducedcentral system fan HP and smaller ductwork), loweroperating cost, the recovery of waste heat and thecapacity for improved air circulation and diffuserperformance.

Fan terminals are available in two basic configurations;series or parallel flow. Each contains a fan motor assemblyand a variable air volume damper to modulate primary air.

In a series unit (Fig. 1), the fan sits in the primaryairstream and runs constantly when the zone isoccupied. In a parallel unit (Fig. 2), the fan sits outsidethe primary airstream and runs intermittently.

Although both terminals can provide central fan HPsavings, each terminal has different inlet static pressurerequirements. Series fan terminals boost both induced airand primary air, so the inlet static pressure need onlyovercome the loss across the damper [less than 0.05"w.g. (12 Pa) with Nailor terminals]. Parallel fan terminalsrequire enough static pressure to overcome the lossesacross the damper, the downstream ductwork anddiffusers [typically 0.25 — 0.5" w.g. (62 — 125 Pa)].

A series fan powered terminal unit mixes primary air withinduced plenum air by using a continuously operating fanduring the occupied mode. It provides a constant volumeof air to the space regardless of load.

As the cooling load decreases, the zone thermostatthrottles the primary air valve. The terminal fan makes upthe difference by inducing more return air from theplenum. At low cooling loads, the primary air may closeor go to a minimum ventilation setting. If the zonetemperature drops still further, the thermostat canenergize optional supplemental heat. The sequencereverses when the load is increased.

The series terminal is therefore a constant volume,variable temperature unit. (See Fig. 3).

Series units should only be used with pressureindependent controls. Series fans must be adjusted to

7-1-11

match the maximum cooling cfm, to ensure that theprimary air does not exceed the fan cfm as this wouldresult in the short-circuiting of primary air directly intothe ceiling plenum and waste energy. A pressureindependent controller and inlet flow sensor controls theprimary air valve to compensate for changes in inlet staticpressure and ensures design cfm is maintained.

Also called an intermittent fan terminal unit, a parallel unitmodulates primary air in response to cooling demandand energizes the integral fan in sequence to deliverinduced air to meet heating demand. The induction fanoperating range should slightly overlap the range of theprimary air valve. A backdraft damper ahead of theterminal fan prevents conditioned air from escaping intothe return air plenum when the fan is off.

During full cooling demand, the thermostat positions theprimary air valve for full airflow while the fan is de-energized. As the cooling load decreases, less primaryair is delivered to the zone as the thermostat modulatesthe valve (functioning as a single duct VAV terminal).

The primary air damper may be set to a minimumposition, (to ensure continuous ventilation), or zero(closed). At a reduced demand for cooling, the fanbecomes energized. The fan has an adjustable startingpoint and may alternatively be set to energize at the pointthat the primary air valve reaches its minimum position or

before it reaches its minimum setting. Overlapping thefan start point and primary air valve minimizes thelikelihood of air stagnation in the conditioned space andthe noticeable air surge when the fan energizes.

With the fan energized, the delivered air temperatureapproaches that of the ceiling plenum. If the zonetemperature continues to drop, the thermostat automaticallyenergizes optional supplemental electric or hot water heat,thereby raising discharge air temperature. Increasing thecooling load reverses the sequence. The parallel terminalunit is therefore variable volume constant temperature onthe cooling cycle and essentially constant volume variabletemperature on the heating cycle. (See Fig. 4).

Fan terminals are installed in the ceiling return air plenumand take return air from the plenum or have the inductionport(s) ducted to the space. For maximum heat pick-upand minimum sound radiation, the assembly shouldideally be located in the ceiling cavity, preferably over acorridor, toward the building core.

Careful consideration should be given to both overallsound level and change in sound level in the space. Withseries terminals the sound remains virtually constant asthe fan runs continuously. With parallel units, theintermittent fan operation will cause a change in soundlevels in the occupied space. This change may be morenoticeable than a constant sound, even if the constantsound is at a higher level (i.e., a series unit), especially inthe fall and spring when fan cycling occurs frequently.

When properly applied, the relatively long distancebetween the fan terminal discharge outlet and theconditioned space it serves minimizes any concern aboutdischarge sounds in the space due to the terminal andonly the radiated sound, below the space where it islocated, need be considered.

Both the primary air damper and fan act as soundsources in both units and each generates discharged andradiated sound.

Series units will have the fan sized for the full airflow anddownstream resistance. Parallel fans with a reduced airvolume heating load should be sized for a reducedresistance downstream of the terminal. While series fansdeliver the total design cooling air volume, parallel unitsgenerally deliver 50 to 75% of that amount. Therefore,series units usually require a larger fan or the same fanrun at a higher speed.

Fan Powered Induction Systems combine the energysaving diversity of single duct VAV shut-off systems withthe additional benefits of heat reclamation. In mostclimates, fan powered systems are a lower operatingcost alternative. Plenum air heating eliminates theinefficiencies inherent in reheating cold primary air.Utilizing warmer plenum air allows for recovery of heatfrom lighting and other heat sources in the building.

Fan Powered Terminals move more air through a room atlow cooling loads and during heating compared to singleduct VAV reheat systems, thereby providing improved aircirculation.

Series flow terminals are rapidly becoming the terminal ofchoice for their superior characteristics of constantvolume delivery, temperature blending and constantsound levels as compared to parallel flow terminals.Some applications may demand constant air volumedelivery regardless of load, e.g., conference rooms,lobbies and large open office areas. Because the seriesunit supplies the downstream external static pressureand reduces the central system pressure requirement,office buildings can take advantage of this design featureand downsize central air handling equipment andassociated ductwork. Series terminals are ideally suitedfor use in low temperature (ice storage) air systems totemper cold [40 – 48°F (4.4 – 9.0°C)] air with warmplenum air before delivering it to the zone

Parallel units may be used in perimeter zones of buildings where loads vary during occupied hours and core zones maintain a constant cooling requirement utilizingsingle duct shut-off type terminal units. Variable volumeairflow to the zone is acceptable in these applications andlow installation and operating costs are desired.

Dependent upon location, loading, operating hours andventilation requirements, either type of fan terminal may bemore advantageous. For an equivalent zone size, seriesterminals may be a little higher in first cost as the fan issized for total airflow whereas a parallel terminal fan issized for the reduced heating airflow only. When fan size isthe same however, installed cost is approximately equal.Series terminals however unlike parallel, reduce theoperating pressure requirement at the central AHU andprovide energy savings.

Since 1985, equipment manufacturers have used ECM motorsin residential air conditioners and furnaces. These motorshave made it possible to achieve SEER ratings of 12 andhigher. Nailor first introduced the GE ECMTM motor to thecommercial HVAC market (ASHRAE Journal, April 1997) asan option for use in series fan powered terminal unitapplications.

The ECM (Electronically Commutated Motor) is an ultra highefficiency programmable brushless DC motor utilizing apermanent magnet motor and a built-in inverter. DC motorsare significantly more energy efficient than AC motors andmuch easier to control. The major weakness of series fanpowered terminal units until now, has been their low fan motorefficiency. The widely used single speed fractional horsepowerpermanent split capacitor (PSC) induction motor incombination with an electronic SCR speed controller isextremely inefficient at typical operating conditions. Due toacoustical considerations, the fan motor is usually adjusted tooperate at considerably less than full load (where PSC motorefficiencies may be as high as 62%). PSC motor efficiencydrops off dramatically when turned down; typically by at leasthalf. Installed PSC motor efficiencies are therefore typically inthe range of only 12 – 45%. ECM motors in contrast, maintaina high efficiency of 65 – 72% at all speeds.

In addition to lower operating costs, EPICTM/ECM motortechnology allows Nailor to pre-set the fan airflow volume atthe factory.

The graphs below show the lower watts per cfm (translatinginto lower operating costs as shown on the next page) andwider operating ranges of series terminals employing ECMmotors versus PSC induction motors.

Soft starts and slewed speed ramps are programmed into theECM motor eliminating stress transmitted to the mountingbracket or hardware. They incorporate ball bearings providingpermanent lubrication unlike sleeve bearings requiring aminimum rpm operation for oiling. The wider operating rangeof the ECM motor allows each model to actually replace two

models using induction motors. This feature alone providesseveral benefits; a simpler product line to choose from, little orno equipment changes necessary when tenants change, moresimilar sized units on the job, decreased spare parts inventoryand increased contractor flexibility. The low operatingtemperature of the ECM motor (essentially ambient) requiresvery little energy to offset the heat gain from the motor versusPSC motors which run hot [typically around 90 – 150°F (32 –66°C)].

These features also extend the life of the ECM motor, whichare expected to provide an average 90,000 hours ofoperation (versus 50,000 hours for a typical PSC motor).This translates into about 25 years for a typical series fanpowered terminal unit. In addition to these standard featuresare two primary benefits, energy savings and the ability topre-set the fan airflow volume at the factory.

Pre-setting the fan airflow (cfm) has always been a problemfor fan powered terminal manufacturers for two majorreasons. First is that AC motors are not synchronousmachines and second the rpm and consequently the unit cfm,changes when static pressure changes. The difficulty in pre-setting the fan lies in estimating the motor workload requiredat the job site in actual working conditions. The fan will notproduce the same volume of air as it did at the factory withoutthe duct work. Because there is no way to accurately predict thedownstream static pressure as it would exist at the job site, itwas impossible to pre-set the fan cfm. The ECMmotors are DCand inherently synchronous machines. The motors areprogrammed to calculate the work they are doing and thencompare the work accomplished to the cfm requirement. Theintegral microprocessor based controller automatically adjuststhe speed and torque in response to system pressure changesand pressure independent constant airflow operation isachieved without the need for an external flow sensorfeedback loop.

Nailor series fan powered terminal units incorporate our owncustom EPICTM fan controller. An electronic PWM volumecontrol device that allows adjustment of airflow volume. Thisvalue can be pre-set on the assembly line. It is fieldadjustable either manually using a screwdriver andvoltmeter locally at the terminal or more conveniently,remotely using a 0 – 10 VDC analog output from a digitalcontroller via the BAS. A fan volume versus DC voltscalibration chart is provided. The importance of this featureis that the balancer never has to go into the ceiling to adjustthe fan. This relieves the balancer of most of his work perzone on fan powered terminal units and related headaches.This also removes the uncertainty of diffuser flowmeasurement with hoods. Laboratory tests show the fan cfmto be accurate within +/- 5% of the factory set point. This isa huge benefit to the owner, the controls contractor, themechanical contractor and the ceiling contractor.

The following graphs show the energy savings of units withECMmotors compared to units with Nailor engineered PSCmotors Since PSC motors used by Nailor are builtspecifically for Nailor fan powered terminal units and aremore efficient than those used by most of our competitors.

A comparison using Nailor units with ECM motors and acompetitor's units with PSC motors would show evengreater savings.

The typical range of operation for the size 3 would be 200 toabout 900 cfm (94 to 425 l/s). The typical range of operationfor the size 5 unit would be 700 to 1700 cfm (330 to 802 l/s).

The payback period varies. It depends on which unit youuse, where you set the cfm, how much you run theequipment and what you are paying for electricity. Thegraphs above are calculated assuming 66 hours per weekoperations and $ .10 per kWh. If you run the equipmentlonger in your building or if you pay more for electricity, thepayback will change proportionally. Considering the pre-setcapability of the motor, there should be an up-front savingson balancing. That should be rebated to the owner andshould be considered as part of the payback from the motor.Typically, with the balancing rebate and the operatingexpenses as shown above, the payback period should beanywhere from 6 to 18 months.

The recommended airflow ranges below are for fan poweredterminal units with pressure independent controls and arepresented as ranges for total and controller specific minimumand maximum airflow. Airflow ranges are based uponmaintaining reasonable sound levels and controller limits usingNailor’s Diamond Flow Sensor as the airflow measuring device.For a given unit size, the minimum, auxiliary minimum (whereapplicable) and the maximum flow setting must be within therange limits to ensure pressure independent operation,accuracy and repeatability.

Minimum airflow limits are based upon .02" w.g. (5 Pa)differential pressure signal from Diamond Flow Sensor onanalog/digital controls and .03" (7.5) for pneumatic controllers.This is a realistic low limit for many transducers used in thedigital controls industry. Setting airflow minimums lower, maycause hunting and failure to meet minimum ventilationrequirements. Where an auxiliary setting is specified, the valuemust be greater than the minimum setting.

The high end of the tabulated Total Airflow Range on pneumaticand analog electronic controls represents the Diamond FlowSensor’s differential pressure reading at 1” w.g. (249 Pa). Thehigh end airflow range for digital controls is represented by theindicated transducer differential pressure.

AHRI Standard 880 "Performance Rating of Air Terminals" is themethod of test for the certification program. The "standard ratingcondition" (certification rating point) airflow volumes for eachterminal unit size are tabulated below. These air volumesequate to an approximate inlet velocity of 2000 fpm (10.2 m/s).

When digital or other controls are mounted by Nailor, butsupplied by others, these values are guidelines only, basedupon experience with the majority of controls currentlyavailable. Controls supplied by others for factory mounting areconfigured and calibrated in the field. Airflow settings onpneumatic and analog controls supplied by Nailor are factorypreset when provided.

Performance Data • NC Level Application GuideModel Series 35S • Series Flow

Explanation of NC Levels:1. NC levels are calculated from the published rawdata and based on procedures outlined in AppendixE, AHRI 885-2008. 2. Discharge sound attenuation deductions are basedon environmental effect, duct lining, branch powerdivision, insulated flex duct, end reflection and spaceeffect and are as follows:

3. Radiated sound attenuation deductions arebased on a mineral tile ceiling and environmentaleffect and are as follows:

4. Min. inlet ΔPs is the minimum static pressurerequired to achieve rated airflow (damper full open).5. Dash (–) in space denotes an NC level of less than 20.

6. Discharge (external) static pressure is 0.25" w.g.(63 Pa) in all cases.7. For a detailed explanation of the attenuationfactors and the procedures for calculating room NClevels, please refer to the "Performance DataExplanation" on page D17 and the "AcousticalEngineering Guidelines" in the Engineering Sectionof this catalog.Discharge attenuation Octave Band

Performance Notes for Sound Power Levels:1. Discharge (external) static pressure is 0.25" w.g. (63 Pa)in all cases, which is the difference (ΔPs) in staticpressure from terminal discharge to the room.Discharge Sound Power Levels (SWL) now include ductend reflection energy as part of the standard rating.Including the duct end correction provides sound powerlevels that would normally be transmitted into anacoustically, non-reflective duct. The effect of includingthe energy correction to the discharge SWL, is highersound power levels when compared to previous AHRIcertified data. For more information on duct end reflectioncalculations see AHRI 880.2. Radiated sound power is the breakout noisetransmitted through the unit casing walls.

3. Sound power levels are in decibels, dB re 10-12 watts.4. All sound data listed by octave bands is raw datawithout any corrections for room absorption or ductattenuation. Dash (-) in space indicates sound power levelis less than 20 dB or equal to background.5. Min. inlet ΔPs is the minimum operating pressure of theprimary air valve section. Asterisk (*) in space indicatesthat the minimum inlet static pressure requirement isgreater than 0.5" w.g. (125 Pa) at rated airflow.6. Data derived from independent tests conducted inaccordance with ANSI / ASHRAE Standard 130 and AHRIStandard 880.

∑ ECM Motor. Size 6 with PSC.* Primary air valve is closed and therefore primary cfm is zero.

Ratings are certified inaccordance with AHRIStandards.

Performance DataECM Option Fan Curves – Airflow vs. Downstream Static Pressure35S Series • Series Flow • EPIC Fan Technology®

3-3-14

NOTES:• The fan curves for the ECM are unlike

those for traditional PSC motors. TheECM is pressure independent andconstant volume in operation at factoryor field set point within the shadedarea. Airflow does not vary withchanging static pressure conditions.The motor compensates for anychanges in external static pressure orinduced air conditions such as filter

loading.

• Airflow can be set to operate onhorizontal performance line at anypoint within shaded area using thesolid state volume controller provided.

• Fan curves shown are applicable to120, 208, 240 and 277 volt, singlephase ECM’s. ECM’s, although DC inoperation, include a built-in inverter.

Electrical Data

* The ECM is a variable horsepower motor. Refer to Selectworks Schedule.

Performance Notes for Sound Power Levels:1. Discharge (external) static pressure is 0.25" w.g. (63 Pa)in all cases, which is the difference (ΔPs) in staticpressure from terminal discharge to the room.Discharge Sound Power Levels (SWL) now include ductend reflection energy as part of the standard rating.Including the duct end correction provides sound powerlevels that would normally be transmitted into anacoustically, non-reflective duct. The effect of includingthe energy correction to the discharge SWL, is highersound power levels when compared to previous AHRIcertified data. For more information on duct end reflectioncalculations see AHRI 880-2011.2. Radiated sound power is the breakout noisetransmitted through the unit casing walls.

Model 35S-OAI

A major concern facing building owners and engineers today is Indoor Air Quality (IAQ). Nailor has developed an 'IAQ' fanpowered terminal unit option that addresses this issue. Nailor's 35S-OAI and 35SST-OAI "StealthTM " fan powered terminalunits with the OAI feature provide a direct connection for outside air to the terminal, in addition to the standard cool airconnection. The OAI feature adds a second pressure independent outside air valve.

New standards practice for HVAC system design, including ANSI/ASHRAE Standard 62.1 — 2010, dictate a minimumamount of ventilation within buildings. Ventilation control has traditionally been done at the central air handling unit;however, this does not always ensure the minimum ventilation to each zone is maintained.

The OAI feature controls outside air to each occupied zone, independently of the primary cooling requirement andtherefore prevents over-ventilation that might otherwise occur when relying on sufficient outside air from the primary airsystem. The OAI feature dual duct inlet design allows the fan powered terminal unit to mix the outside air to the zone withthe primary cooling air. The outside air pressure independent air valve provides a constant volume to the zone regardlessof thermal conditions. This fixes the outside air requirement for the zone without putting excessive demands for outsideair on the primary air handler. In turn, the primary air handler does not have to reset outside air rates for all zones in thebuilding. The first cost of the outside air handler and its associated ductwork can be offset by the savings provided byrunning smaller outside air volumes for those zones with lower occupancy rates.

The OAI feature is perfect for schools. The high occupancy in the classrooms is served without creating excessive loadsat the primary air handler serving zones with lower occupancies. Office buildings with conference rooms, kitchen areasand workrooms with copiers can also benefit. When these areas are occupied and require large percentages of outsideair, the primary air handler does not have to reset the outside air for all the office spaces in the building.

When integrated with a DDC building management system, the amount of outside air can be tracked and logged to ensure'IAQ' standards for each zone are met and by using occupancy sensors, the outside air volume for individual zones canbe reset.

Nailor's 35S-CVP Series is perfect for use as a pressurization unit for critical environment applications. Utilizing Nailor's EPICTM

fan technology, the fan and blower operate as a pressure independent constant volume assembly. This means that the airflowthrough the unit will not change due to pressure changes in the system as the filter loads or as the pressure in the exhaust orsupply ducts change. The induction port is closed so that the unit operates as a straight through cooling unit. Both electric andhot water reheat options are available. HEPA filters may be installed either upstream or downstream of the terminal unitdepending on whether the room pressure is negative or positive. The fan and damper are set to maintain pressure in the roombeing served. Temperature control is through reheat in the unit. The CVP feature allows designers to take advantage of Nailor'sEPICTM fan technology and its associated low operating costs for pressurization.

"Smart" Brushless DC motor technology provides continuous monitoring, automatic compensation and precise control andmaintenance of discharge airflow regardless of discharge static pressure variations incurred by a HEPA filter. Available inthree units sizes, suitable for 200 – 3000 cfm (94 – 1416 l/s) zone designs with up to a maximum total external dischargestatic pressure of 1.0" w.g. (249 Pa).

Ideally, suited to clean room applications such as hospital isolation wards, operating rooms, pharmaceutical andbiotechnology manufacturing and research facilities.

• Unique 16 ga. (1.6) galvanized steelchannel space frame constructionprovides extreme rigidity and 20 ga.(1.00) casing components.

• 16 ga. (1.6) galvanized steelinclined opposed blade primary airdamper operating on a 45° arc.

• EPICTM/ECM motor fan technology.

• Solid metal 'IAQ' inner liner.





• Motor blower assembly mounted onspecial 16 ga. (1.6) angles andisolated from casing with rubberisolators.


• Available with electric or hot waterreheat.

NOTES:• The fan curves for the ECM are

unlike those for traditional PSCmotors. The ECM is pressureindependent and constantvolume in operation at factoryor field set point within theshaded area. Airflow does notvary with changing staticpressure conditions. The motorcompensates for any changesin external static pressure orinduced air conditions such asfilter loading.

• Airflow can be set to operateon horizontal performance lineat any point within shaded areausing the solid state volumecontroller provided.

• Fan curves shown areapplicable to 120, 208, 240and 277 volt, single phaseECM’s. ECM’s, although DC inoperation, include a built-ininverter.

Performance Notes for Sound Power Levels:1. Discharge (external) static pressure is 0.25" w.g. (63 Pa)in all cases, which is the difference (ΔPs) in staticpressure from terminal discharge to the room.Discharge Sound Power Levels (SWL) now include ductend reflection energy as part of the standard rating.Including the duct end correction provides sound powerlevels that would normally be transmitted into anacoustically, non-reflective duct. The effect of includingthe energy correction to the discharge SWL, is highersound power levels when compared to previous AHRIcertified data. For more information on duct end reflectioncalculations see AHRI 880-2011.2. Radiated sound power is the breakout noisetransmitted through the unit casing walls.

Performance DataECM Option - Fan Curves – Airflow vs. Downstream Static Pressure37S Series • Low Profile • Series Flow


NOTES:• The fan curves for the ECM are unlike those for traditional

PSC motors. The ECM is constant volume at factory orfield set point and airflow does not vary with changing staticpressure conditions. The motor compensates for anychanges in external static pressure or induced air conditionssuch as filter loading.

• Airflow can be set to operate on horizontal performanceline at any point within shaded area using the solid statevolume controller provided.

• Fan powered terminal units featuring the optional ECMhave considerably wider turn-down ratios thanconventional PSC motors. Hence, a reduced number ofunit sizes are required in order to provide the same fanairflow range when compared with terminals equipped withPSC motors. A reduction in the number of different terminalsizes required on a typical project simplifies design lay-outand installation and reduces inventory of field service parts.

• Fan curves shown are applicable to 120, 208, 240 and 277volt, single phase ECM’s. ECM’s, although DC inoperation, include a built-in inverter.

Performance Notes for Sound Power Levels:1. Discharge (external) static pressure is 0.25" w.g. (63Pa) in all cases, which is the difference (ΔPs) in staticpressure from terminal discharge to the room.

Discharge Sound Power Levels (SWL) now include ductend reflection energy as part of the standard rating.Including the duct end correction provides sound powerlevels that would normally be transmitted into anacoustically, non-reflective duct. The effect of includingthe energy correction to the discharge SWL, is highersound power levels when compared to previous AHRIcertified data. For more information on duct end reflectioncalculations see AHRI 880-2011.2. Radiated sound power is the breakout noisetransmitted through the unit casing walls.

Performance DataECM Option Fan Curves – Airflow vs. Downstream Static PressureModel Series 37SST "Stealth™" • Low Profile • Series Flow


NOTES:• The fan curves for the ECM are unlike those for traditional

PSC motors. The ECM is constant volume at factory orfield set point and airflow does not vary with changing staticpressure conditions. The motor compensates for anychanges in external static pressure or induced air conditionssuch as filter loading.

• Airflow can be set to operate on horizontal performanceline at any point within shaded area using the solid statevolume controller provided.

• Fan powered terminal units featuring the optional ECMhave considerably wider turn-down ratios thanconventional PSC motors. Hence, a reduced number ofunit sizes are required in order to provide the same fanairflow range when compared with terminals equipped withPSC motors. A reduction in the number of different terminalsizes required on a typical project simplifies design lay-outand installation and reduces inventory of field service parts.

• Fan curves shown are applicable to 120, 208, 240 and 277volt, single phase ECM’s. ECM’s, although DC inoperation, include a built-in inverter.
