Background
With Ecodesign Directive 2009/125/EC (ErP Directive) the European Union has defined requirements for the environ-mentally sound design of energy consuming products. This directive is part of the 20-20-20 target, according to which energy use should be reduced by 20% and the share of re-newable energies increased by 20%, by 2020. It replaces the EuP Directive 2005/32/EC, which referred to a range of electrical products, mainly end user appliances. Concrete measures will be defined through more detailed regulations but in the first stage, starting January 01, 2013, fans with input power ranging from of 125 W to 500 kW will have to meet specific efficiency values. On January 01, 2015, the second stage with higher efficiency values becomes effec-tive and this will consider the entire fan, not just the fan mo-tor.
Use of the CE symbol will be conditional on compliance with all efficiency requirements.
IEC-motors
Starting June 2011, IEC-motors will have to comply with the requirements of Directive (2009/640/EC) and will have to reach at least efficiency class IE2 (previously: eff1), IEC-motors of a lower efficiency class will no longer be allowed to be marketed within the EU. Therefore Rosenberg has al-ready completed converting all fans with IEC-motors to IE2-level. These are clearly indicated in the latest price list 2011.
The ErP DirectiveWhat you should know now and consider for the future
External rotor motors
External rotor motors, which are usually used as fan drives, are not affected by Directive (2009/640/EC). However, from January 2013, all fans will have to comply with the ErP Direc-tive for fans (2011/327/EC).
EC technology
Rosenberg’s energy efficient EC fans already fulfil the ef-ficiency values of the ErP regulations. They are 100% ErP ready, now!
In comparison to conventional AC driven fans, considerably higher efficiency levels, better than 90%, are achieved due to reduced losses in the EC motor. EC motors are easily speed controllable via integrated electronics and offer even greater efficiency over AC motors in this condition, as a re-sult air volume can be readily adjusted to any possible oper-ating point. The integrated, intelligent electronics not only enables speed control but also additional functions, for ex-ample; constant airflow, pressure or air quality control.
Rosenberg EC fans fulfil the highest standards of energy and economic efficiency.
You will find further information on our EC fans in our bro-chure “Standard fans with energy efficient EC technology“, which we will send to you upon request, or you can find a pdf version to download on www.rosenberg.eu .
Are there exceptions?
For the time being, “yes”. Fans for high specification require-ments such as ATEX, smoke extract, ambient temperatures above 100°C and fans for railway technology are excluded.
The following end products are also currently excluded - roof fans, duct fans, tube fans and box fans (e.g. Unobox and Ze-robox). In the future, these end products will be covered by a specific regulation. Nevertheless the motor/impeller combi-nations used in these fans will have to adhere to the existing efficiency values of directive (2011/327/EC) for fans. Does existing equipment have to be retrofitted?
The answer is “no“. Existing equipment does not need to be retrofitted. Only fans and fan systems marketed within the EU after January 01, 2013 will be affected. There will be a transition period for replacement fans until January 01, 2015, for fans sold into the market before January 01, 2013.
Does the ErP Directive apply globally?
The Directive applies to energy consuming products, which are produced in the EU or imported into the EU. It does not apply to products designated for export out of the EU. How-ever it is assumed that this subject will become an issue in other countries in the near future.
Will fans become more expensive due to the new directive?
Costs for fans already compliant with the requirements will not increase with the introduction of the ErP Directive. There may be additional costs associated with mandatory techni-cal modifications for certain products, however a return on investment will be achieved in a short timescale by signifi-cant improvements in efficiency. Eventually, the end user benefits from a reduction in energy consumption costs and the whole environment from reduced CO2 emissions!
How to identify ErP compliant fans?
Starting in 2013 you will be able to identify fans, which are compliant with the ErP Directive by the CE symbol placed on the product. In addition, all Rosenberg fans will be marked with the “ErP ready“ logo on the product, in all Sales docu-
Frequently asked Questions
ments and brochures, as well as in the fan selection soft-ware RoVent.
What advantages does the Directive provide for me as customer?
With the application of this legal regulation only energy ef-ficient fans will be able to be sold in the EU. This will allow you to save up to 65% in energy costs, depending on the application and you don’t need to wait until 2013, energy ef-ficient fans, especially with EC technology, are already avail-able, today!
Does the ErP Directive also affect air handling units?
A preliminary study to evaluate the status quo and possible energy savings has already been commissioned by the EU. This is to be finalized by the end of 2011 and, based on the findings, a regulation will be drafted.
However, air handling units are already affected through the motors used and, starting in 2013, through complete fans, because of the efficiency requirements in existing direc-tives.
Besides air handling units (for non-residential use), this sepa-rate legislation will also deal with and impose limit values on small air conditioning units and heat recovery systems as well as the previously mentioned roof fans, duct fans, tube fans and box fans.
Active participationof Rosenberg
“The European Ventilation Indus-try Association” (EVIA) is the um-brella organization of the European ventilation industry. Founded in July 2010, it is composed of three work groups for: “..ventilation units for residential applianc-es“, “..ventilation units for non-residential appliances” and “ ..fans”. With the establishment of the EVIA, the requests and concerns of the European ventilation industry have been met with one voice in the European legislature and as a founding member of the EVIA, Rosenberg is participating actively in the composition of future European guidelines and regulations.
Technical Information
All Rosenberg fans are equipped with direct driven external rotor motors, which have decisive advantages in comparison with conventional fans:
- high life time
- compact design
- motor and impeller assembled to one unit
- the speed is 100% controllable (auto transformers; controller)- low starting currents
All our fans have motor protection through thermal contacts in the motor windings as standard. The impellers are balanced dynamically and statically according to DIN ISO 1940 quality G2.5.
AC Motor
The drive has due to an external rotor motor a space saving, compact and attractive design. The motor is fitted within the impeller, which enables the best possible cooling. For this reason a 100% variable speed control can be guaranteed. V-belts,
additional tension bars and motor mounting devices are not necessary. Only well-dimensioned ball-bearings, fitted on both sides and life time greased are used. Both ball-bearing
seats are ground to high precision in one work pro-cess to eliminate any vibrations.
External rotor motors have extremely low starting currents. The motors apply mostly to protection class IP54 according to DIN EN 60034-5. The win-dings comply to isolation class F. In addition the windings have a standard moisture impregnation.
EC Motor
The used EC motors are characterized by a very high degree of efficiency, also in part-load operational range as well as by
an ideal steering mechanism and automatic control action. They are easy to connect, individually pre-configured, compact in construction and show a high power density. Implementation of additional functions (e. g. pressure- and volume-control) is possible. Rosenberg EC motors meet mostly de-gree of protection category IP54; input voltage of 380V-480V (50/60Hz). Rosenberg EC motors are continuous speed controlable and have an integra-ted motor protection.
IEC standard motor
The used three phase IEC norm motors of type B3 are in protection class IP55, with insulation class F, 2-pole and 4-pole realized.
For the conveying of explosive atmospheres in zone 2 we offer fans according to Atex guideline 94/9/EG (Atex 95) in tempera-ture class T1 to T3. Fans for the conveying of and installation in zone 1 are also available on request.

Air performance curves
The air performance curves have been established using the inlet test method in the test chamber as shown below accor-ding to DIN 24163. They show pressure increase as a function of the volume flow and are valid for air with a density of 1,2 kg/m³ with a temperature of t=20°C. The mounting position was selected according to the operation conditions to each fan type. Important note: Power consumption of fan changes proportio-nal to density of conveyed air/gas.

Centrifugal Fans
Features and Construction
The high efficiency centrifugal fans have been developed es-pecially for modern ventilation and air conditioning applications and are ideal for the movement of air and light aggressive gas and vapours. The size comply with standard R20 and are in accordance with DIN323. The designation of size corresponds to the outside diameter of the impeller.
Casing
The casing of the high efficiency centrifugal fans are made of galvanized sheet steel and the side parts of the scroll is assembled with the spirally shaped guide plate through a standing seam. The side parts are produced with nut sets to fix the mounting brackets, which can be fixed in steps of 90°. Impellers
The drum impeller is made of galvanized sheet steel, and is mounted directly to the rotor of the external rotor motor and are balanced dynamical-ly at two levels together with the rotor according to quality level G2.5 to DIN1940.
Electrical connection
The motors are fitted with an outgoing cable. The electrical connection can be made via an IP44 terminal box, which is supplied loose.
Direction of rotation
Direction of rotation for fan types ERA is clockwise viewed from the inlet side, but for fan types DRA it is counter-clock-wise viewed from the cable outlet.
Air performance curves
The performance curves for these fan types have been mea-sured in mounting position B (installed on the pressure side and open on the suction side) and show the total pressure increase �pt as a function of the air flow. The dynamic pres-sure �pd2 refers to the flange cross section at the outlet side of the fan.
Noise levels
The bordered values printed in the performance curve dia-grams show the „A“ weighted LWA6 sound power level (fan outlet). Determination of „A“ weighted LWA5 sound power le-vel at fan inlet: LWA5 [dB(A)] = LWA6 [dB(A)] - 3 dB
The „A“ weighted sound pressure level LPA at a distance of 1 metre is calculated approximately by deducting 7 db(A) from the „A“ weighted sound power level. It is important to note that the reflection and room characteristic as well as natural frequencies influence the sound pressure levels a different way. The relative octave sound power level LWArel at octave medium frequency you can find on the table on each fan type page.

High Efficiency Centrifugal Fans with slippage characteristics
Centrifugal Fans
Features and Construction
By use of a special designed external rotor motor with high rotor resistance, in connection with forward curved centrifugal impellers, we developed a centrifugal fan series with extre-mely high slippage characteristics. The external rotor motor adjusts to the operating conditions and therefore changes the R.P.M. at varying system resistances, regarding on the total pressure. This is a special advantage in systems with variable resistances occured from dirty filters, controlled dampers in duct installations or clean-room applications.
Casing
The spiral scrolls are made of galvanized sheet steel. On request plastic coating is possible (at ad-ditional costs).
Impellers
The drum impeller is made of galvanized sheet steel, and are mounted directly to the rotor of the external rotor motor and are balanced dynamical-ly at two levels together with the rotor according to quality level G2.5 to DIN1940.
Electrical connection
The motors are fitted with flying lead. The electri-cal connection can be made via an IP54 terminal
box, which is supplied loose.
Direction of rotation
Direction of rotation for fan types ERA is counter-clockwise viewed from the inlet side, and for fan types DRA it is also counter-clockwise viewed from the cable outlet.
Air performance curves
The performance curves for these fan types have been mea-sured in mounting position A (on suction and pressure side no ducts connected) and show the total pressure increase �pt as a function of the air flow. The dynamic pressure �pd2 refers to the flange cross section at the outlet side of the fan.
Noise levels
The bordered values printed in the performance curve dia-grams show the „A“ weighted LWA6 sound power level (fan outlet). Determination of „A“ weighted LWA5 sound power le-vel at fan inlet: LWA5 [dB(A)] = LWA6 [dB(A)] - 2 dB [up to size 282]
LWA5 [dB(A)] = LWA6 [dB(A)] - 4 dB [from size 314]
The „A“ weighted sound pressure level LPA at a distance of 1 metre is calculated approximately by deducting 7 db(A) from the „A“ weighted sound power level. It is important to note that the reflection and room characteristic as well as natural frequencies influence the sound pressure levels a different way. The relative octave sound power level LWArel at octave medium frequency you can find on the table on each fan type page.

Backward Curved Centrifugal Fans
Features and Construction
The high efficiency centrifugal fans with backward curved im-peller have been developed especially for modern ventilation and air conditioning applications and are ideal for the move-ment of air and light aggressive gas and vapours. The sizes comply with standard R20 and are in accordance with DIN323. The designation of size corresponds to the outside diameter of the impeller.
Casing
The casing of the high efficiency centrifugal fans are made of galvanized sheet steel and the side parts of the scroll is assembled with the spirally shaped guide plate through a standing seam. The side parts are produced with nut sets to fix the mounting brackets, which can be fixed in steps of 90°. From size 450 the units are supplied in rectan-gular sheet metal construction.
Impellers
The backward curved impeller is made of alumi-nium, and is mounted directly to the rotor of the external rotor motor and are balanced dynamically at two levels together with the rotor according to quality level G2.5 to DIN1940.
Electrical connection
The motors are fitted with an outgoing cable. The electrical connection can be made via an IP44 terminal box, which is supplied loose.
Direction of rotation
Direction of rotation for fan types EHA is clockwise viewed from the inlet side, but for fan types DHA it is counter-clock-wise viewed from the cable outlet.
Air performance curves
The performance curves for these fan types have been mea-sured in mounting position B (installed on the pressure side and open on the suction side) and show the total pressure increase �pt as a function of the air flow. The dynamic pres-sure �pd2 refers to the flange cross section at the outlet side of the fan.Noise levels
The bordered values printed in the performance curve dia-grams show the „A“ weighted LWA6 sound power level (fan outlet). Determination of „A“ weighted LWA5 sound power le-vel at fan inlet: LWA5 [dB(A)] = LWA6 [dB(A)] - 6 dB
The „A“ weighted sound pressure level LPA at a distance of 1 metre is calculated approximately by deducting 7 db(A) from the „A“ weighted sound power level. It is important to note that the reflection and room characteristic as well as natural frequencies influence the sound pressure levels a different way. The relative octave sound power level LWArel at octave medium frequency you can find on the table on each fan type page.

Axial Fans
Features and Construction
High efficiency axial fans are used wherever large air volumes must be conveyed against low up to medium pressure.
High efficiency axial fans with square inlet cone are used for ventilating restaurants, gymnasiums, conference rooms, work-shops, ware-houses, swimming pools and greenhouses.
High efficiency axial fans with double flange ring are used in duct systems for air conditioning, cooling and drying applica-tions.
Casing
The casings of high efficiency axial fans are made from galva-nized sheet steel and are plastic coated.
Impellers
The high efficiency axial fans have aerodynamically profiled blades (sizes 200 to 300 made from galvanized and lacquered sheet steel ; from size 315 to 630-6 made of plastic and sizes 630-4 up to 1000 made of aluminium).
The blades are made of galvanized sheet metal, and are moun-ted directly to the rotor of the external rotor motor and are ba-lanced dynamically together with the rotor according to quality level G2.5 to DIN1940.
Electrical connection
The motors are fitted with an outgoing cable. The electrical connection can be made via an IP44 terminal box, which is supplied loose.
Air performance curves
The performance curves for these fan types have been mea-sured in mounting position A (free inlet ; free outlet) and show the pressure increase �pfa as a function of the air flow ; version with inlet cone and without protection guards.
Noise levels
The bordered values printed in the performance curve dia-grams show the „A“ weighted LWA6 sound power level (fan outlet). Determination of „A“ weighted LWA5 sound power le-vel at fan inlet: LWA5 [dB(A)] = LWA6 [dB(A)] - 3 dB
The „A“ weighted sound pressure level LPA at a distance of 1 metre is calculated approximately by deducting 7 db(A) from the „A“ weighted sound power level. It is important to note that the reflection and room characteristic as well as natural frequencies influence the sound pressure levels a different way. The octave sound power level LWA at octave medium frequency you can find on the table on each fan type page.
