AmAir 300


High Quality Prefilters

Excellent media perfor-mance in high humidity

conditions High tensile strength

media

Environment-friendlymaterials

Sturdy, reliableconstruction

High performance, environment

friendly media

With the new AmAir 100 and 300series of prefilters AAF has risen tothe challenge of designing anenvironment-friendly product withthe necessary performance charac-teristics built-in. These filters feature

a new 100% synthetic media packwhich provides excellent perfor-mance in conditions of high relativehumidity and moisture. When themedia becomes wet, resistance mayrise temporarily only to subside whenthe media starts to dry. The syntheticmedia displays great tensile strength,reducing the chance of damageduring handling and operation. Themedia is environment and user

friendly: it does not contain anyharsh resins or artificial colouring. Itcan therefore be readily disposed ofby landfill or incineration.

Sturdy, reliable construction

The pleated media pack of bothrange of filters is housed within a

sturdy double walled, die cut box,beverage board frame. To ensure themedia pack does not rack ordeteriorate under difficult operatingconditions, it is bonded to the insideof its frame at all points of contactand retained in position by retainersat the air leaving and air enteringsides. On the air leaving side of themedia pack a wiremesh pleat supportgrid maintains equidistant spacing

between pleats, ensuring that dust iscollected evenly over the entiresurface of the media. Media usage ismaximized resulting in a moregradual rise in resistance, which inturn has a positive effect on energyconsumption and service life.

ApplicationsClassified G4 in accordance withEN 779, AmAir 100 and 300 areideal for protecting more expensivesecondary air filters from prematuredust loading and replacement. Asprimary filters, they will also helpreduce HVAC maintenance costs bypreventing unnecessary dust build-upon coils, fans and duct work.

VariCel filters with Intersept antimicrobial are designed specifical-

ly to improve Indoor Air Quality (IAQ). Air filters are designed totrap and concentrate particulate air contaminants including viablefungal and bacterial spores. The presence of Intersept antimico-bial preservative in the filter media is intended to preserve the in-tegrity of the media throughout the useful life of the filter.Antimicrobial preservatives are not meant to increase the efficiencyof the filter, nor to kill microorganisms "on the fly" as they passthrough a filter. Intersept is EPA registered and environmentallysafe.

Engineered For A Variety Of Applications

Designed To Improve Indoor Air Quality

Type SH Single Header VariCel filters are designed forsystems originally supplied by AAF International. A

unique 1316" flanged header on the air entering side al-lows the filter to be easily inserted and latched into front andside access systems.

Type DH Double Header VariCel filters are designed toupgrade air cleaning performance and reliability. Two1316" thick flanged headers make the filters compatible

with the holding frames and latching devices of various manu-facturers, including rear access systems.

XL Series VariCel filters, single header (XL-S) and double header(XL-D), contain up to 67% more media and offer more than twice theservice life of standard single and double header models.

Corrugated Aluminum Separators

with Rolled Edges maintain uniform

pleat spacing for optim um airflow. The

separators are rolled to eliminate

sharp edges, preventing m edia dam-

age during shipping and personal in-ju ry du rin g i ns tall ati on .

Crimped Rear Flanges (SH) are rolled

over and riveted to add strength, elimi-

nate sharp edges, and prevent bypassleakage.

Media Pack Restraint

Steel brace on air leaving

side adds support to th e

media pack.

Media Pack Sealant A layer

of high efficiency media seals the

media pack into the cell sides.

The media sealant prevents by-

pass leakage and damage to the

media and separators during

shipping and handling. By allow-

ing slight movement of th e media

pack when the filter is jarred, the

cushioning sealant helps prevent

tears and punctur es to the m edia.

VariCel media is manufacturedwith two layers of glass fibers:coarser fibers on the air enteringside and finer fibers on the airleaving side.

Our dual density design allows

dirt particles to be collectedthroughout the entire depth ofthe filter utilizing the full clean-ing potential of the media. Maximum dust holding capacity ex-tends the life of the filter, minimizing operating costs.

The water resistant media can withstand intermittent exposure towater, making VariCel filters ideal for installations in humid areasor where the filters are exposed to moisture.

AIRFLOW

VariCel's rigid constructionwith supported pleat mediapack maintains a compact,unitized structure even undertough operating conditions.Variable air velocity and re-peated fan shutdown do not

compromise performance.

Unitized Construction

Interlocked header and cellsides, along the entire lengthof each side, provide maxi-mum sealing. Competitive fil-ters are designed with loosefitting headers which allowgreater potential for bypassleakage.

BUILT RUGGED FOR DEPENDABLE PERFORMANCE

Pleats and Separators

Bonded For Strength

During the pleating process,

spots of glue are applied tobond each separator to the ad-jacent pleat. This solidifies themedia pack to minimize move-ment and prevent media dam-age. Burst strength isincreased to prevent the filterfrom blowing out under vari-able air volume conditions orunusually high resistance.

Galvanized steel headers andcell sides resist damage during

shipping and handling, andprevent corrosion over longservice life. (HT VariCel filtersare constructed of aluminizedsteel.)

AstroCel I HC

High air volume filter:3000 m3/h

Classified H12, H13 andH14 according toEN1822

Space saving design

Saves energy in existinginstallations

AstroCel I High Capacity are classified

H12, H13 and H14 in accordance with

EN1822 and are designed for

applications in which a high volume of

air has to be throughput. Because of their

high capacity, fewer filters are needed to

handle the same volume of air compared

to other HEPA filters of the same size.

AstroCel I HC filters owe their high

capacity to a unique separator design

which allows denser packing of the filter

media. The benefits to the customer are

numerous:

In new installations, fewer filters mean

less costly installation space is

necessary.

In existing installations, low pressure

drop means lower energy costs and

longer service life.

AstroCel III 3400 MDF

H12 and H13 inaccordance with EN1822

3400 m3/h air volumesaves space

Low energy consumption


AstroCel III is classified H12 or H13 in

accordance with EN1822. The filter

displays excellent efficiency on fine

particulate matter and is designed for use

in high air volume applications upto

3400 m3/h. Due to its high capacity the

filter has several benefits: in new

installations, fewer filters are required to

handle the same volume of air comparedto HEPA filters of the same size with a

lower capacity. As a result, less

installation space is required and

installation time is significantly reduced.

In existing installations, the filter's high

media area ensures a low pressure drop

which reduces energy costs. Other

benefits include:

high quality MDF cell sides ensure a

smooth, non-shedding construction

easy installation

Non-Laminar Flow Cleanrooms

Basic Design and Operating Considerations


In a non-laminar cleanroom or, to use its

official name, non-unidirectional airflow

cleanroom, air enters the room via filters

in the ceiling, and is exhausted via grilles

in the wall close to the floor.

The principle of this technique is based

on allowing air to flow along irregular,

random paths in a turbulent way.

The success of this technique hinges on

optimizing the mixing of clean incoming

air with dust laden air in the room and

thereby diluting the contamination level

in the cleanroom and lowering the

number of particles per m3. The supply

of clean air is therefore the factor which

determines the success of this technique.

In general, the greater the frequency with

which the air is renewed the lower the

contamination build-up in the room andthe greater the rate with which

impurities are diluted. On an hourly

basis, the number of air changes in a

room can vary between 10 and 50,

depending on the type of work and the

achievable Class of the room.

Although more unpredictable than

laminar airflow cleanrooms, in many

applications a non-laminar flow room

can be a cost effective solution, especiallywhen local laminar flow work stations

are operational in the room.

Laminar Flow Cleanrooms

The principle of laminar airflow or, to

be more precise, unidirectional airflow

cleanrooms is based on air moving along

parallel streamlines at a uniform velocity

of 0.3 to 0.45 m/s with as little

turbulence as possible between the place

where the air enters and exits the room.

The principle is based on expelling any

dust in the airflow by the shortest route.

Basically, there are two types of laminar

airflow cleanroom:

a) Vertical downflow

b) Horizontal crossflow

Vertical Downflow

In a vertical downflow cleanroom, air

enters the room via filters in the ceiling

surface and is exhausted via a perforated

floor. This downward aiflow flushes

contaminated air particles out of the

room via the floor, thus preventing a

build-up of contaminated particles.

Particles generated at one work station

are therefore removed before they have

the chance to migrate. The air velocity

in this type of cleanroom is usually 0.3

to 0.45 m/s.

Horizontal Crossflow

In a horizontal crossflow cleanroom, the

direction of airflow is from left to right

or right to left across the room. Air

enters the room via filters in one wall

and is exhausted and/or recirculated via

a bank of filters and perforated panels in

the opposite wall. The air velocity has to

be established at a sufficiently high level,

usually 0.45 m/s, to counter the effects

of upward thermal movement of

particles. In work stations close to the

high efficiency filter wall, Class 100 or

better is possible.

Since the flow of particles in this type of

cleanroom is in the horizontal direction,

the particle contamination generated atone work station can be transported to

work stations further downstream of the

filters. This, however, is dependent on

the type of work or the process(es) being

carried out in the cleanroom. Horizontal

crossflow is nevertheless a very practical

and cost effective system, particularly in

cleanrooms which have to be built in

existing spaces with limited ceiling

height.

EN779


New European Standard for Coarse and Fine Filters

In 1993, the European Committeefor Standardization, TechnicalCommittee 195, Work Group 1

(CEN/TC195-WG1) established anew standard for general ventilationfilters. With the introduction of thisstandard under document name EN779, member countries of theEuropean Union are obliged to issuetheir own national version of thisstandard within the existingframework of their own nationalstandards organizations.For example, BS EN 779 in the U.K.

and DIN EN 779 in Germany.EN 779 is based on existingdocuments such as EUROVENT

4/5, and ASHRAE 52.1:1992, but isin fact more stringent than either ofthese standards. The standardincorporates a new system ofclassification for Coarse and Finefilters based on an average dust spotefficiency at a specified final pressuredrop.

Filters with an initial dust spotefficiency below 20% are classified as

Arrestance Filters (Coarse Filters) inthe range G1 - G4. Final pressuredrop for certification is specified at

250 Pa maximum. Filters with aninitial dust spot efficiency above 20%are classified as Efficiency Filters(Fine Filters) in the range F5 - F9.The final pressure drop forcertification is set at 450 Pamaximum.

The table summarizes theclassification of the EN 779 forgeneral ventilation filters.

Note:For your information, the CEN/TC 195 Work Group 1 will continue to upgrade its standardization for general ventilation filters.To this end, EUROVENT has produced a particle count method under document name EUROVENT 4/9 which will form thebasis for a future new standard. WG 1 has also expressed its intention to work in closer liaison with ASHRAE on this subject.

On a flat sheet of media, the MPPS is determinedfor the given media velocity. This can be done

with a laser spectrometer or a combination ofelectrostatic classifier and CNC (CondensedNucleus Counter).

The filter is assembled with the specified mediagrade and amount of media to comply with thedefined media velocity.

The filter is challenged with an aerosol and at theMPPS both the local and overall efficiency isdetermined with either a CNC or laserspectrometer.

Leaks are specified as maximum allowable localpenetration at the MPPS and must not exceed5 x the overall penetration.

The filter is classified according to the test resultsin the range H10 - H14 for HEPA,U15 - U17 for ULPA.

Notes:

Filters in the class H10, H11 and H12 do not require verification of local penetration. Filters in the classification H13 and H14 may, as an alternative, be verified with the visual oil-smoke test (previously known as DIN 24.184),

which is accepted as equal or more searching than the specified local penetration. U17 is an exception to the rule. In this case local penetration may not exceed 20 x the overall penetration value.
