AmAir® 300 High Quality Prefilters

● Excellent media performance in high humidity conditions ● High tensile strength media ● Environment-friendly materials ● Sturdy, reliable construction

With the new AmAir 100 and 300 series of prefilters AAF has risen to the challenge of designing an environment-friendly product with the necessary performance characteristics built-in. These filters feature a new 100% synthetic media pack which provides excellent performance in conditions of high relative humidity and moisture. When the media becomes wet, resistance may rise temporarily only to subside when the media starts to dry. The synthetic media displays great tensile strength, reducing the chance of damage during handling and operation. The media is environment and user

friendly: it does not contain any harsh resins or artificial colouring. It can therefore be readily disposed of by landfill or incineration.

High performance, environment friendly media

Sturdy, reliable construction

The pleated media pack of both range of filters is housed within a sturdy double walled, die cut box, beverage board frame. To ensure the media pack does not rack or deteriorate under difficult operating conditions, it is bonded to the inside of its frame at all points of contact and retained in position by retainers at the air leaving and air entering sides. On the air leaving side of the media pack a wiremesh pleat support grid maintains equidistant spacing

U.L. Class 1

Ideal For Difficult Operating Conditions -

Variable air volume Turbulent airflow Repeated fan shutdown High temperature operation High humidity Intermittent exposure to water such as seacoast installations

Designed To Improve Indoor Air Quality

VariCel filters with Intersept® antimicrobial are designed specifically to improve Indoor Air Quality (IAQ). Air filters are designed to trap and concentrate particulate air contaminants including viable fungal and bacterial spores. The presence of Intersept® antimicobial preservative in the filter media is intended to preserve the integrity of the media throughout the useful life of the filter. Antimicrobial preservatives are not meant to increase the efficiency of the filter, nor to kill microorganisms "on the fly" as they pass through a filter. Intersept® is EPA registered and environmentally safe.

Engineered For A Variety Of Applications

Type SH Single Header VariCel filters are designed for systems originally supplied by AAF International. A unique 13⁄16" flanged header on the air entering side allows the filter to be easily inserted and latched into front and side access systems.

Type DH Double Header VariCel filters are designed to upgrade air cleaning performance and reliability. Two 13 ⁄16" thick flanged headers make the filters compatible with the holding frames and latching devices of various manufacturers, 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 the service life of standard single and double header models. High Temp Series VariCel filters are designed for systems operating from 350˚-900˚F. Constructed of aluminized steel, High Temperature VariCel filters offer rated efficiency with proven reliability over the life of the filter. See page 4 for models and temperature limits. Type NH Series VariCel filters are designed for special sizes and applications, including incineration and compaction disposal systems. Manufactured of fireretardant, 3⁄4" thick, heavy wall particle board, Type NH VariCel filters (U.L. Class 1) are operable at temperatures up to 200˚F. The filters are constructed without headers and cell sides are flush with front face dimensions.


BUILT RUGGED FOR DEPENDABLE PERFORMANCE

Crimped Rear Flanges (SH) are rolled over and riveted to add strength, eliminate sharp edges, and prevent bypass leakage.

Media Pack Restraint Steel brace on air leaving side adds support to the media pack. Corrugated Aluminum Separators with Rolled Edges maintain uniform pleat spacing for optimum airflow. The separators are rolled to eliminate sharp edges, preventing media damage during shipping and personal injury during installation.

VariCel's rigid construction with supported pleat media pack maintains a compact, unitized structure even under tough operating conditions. Variable air velocity and repeated fan shutdown do not compromise performance. Unitized Construction Interlocked header and cell sides, along the entire length of each side, provide maximum sealing. Competitive filters are designed with loose fitting headers which allow greater potential for bypass leakage. Header VariCel Construction Cell Side Header Typical Competitive Construction

Pleats and Separators Bonded For Strength During the pleating process, spots of glue are applied to bond each separator to the adjacent pleat. This solidifies the media pack to minimize movement and prevent media damage. Burst strength is increased to prevent the filter from blowing out under variable air volume conditions or unusually high resistance. Galvanized steel headers and cell sides resist damage during shipping and handling, and prevent corrosion over long service life. (HT VariCel filters are constructed of aluminized steel.) Easy Installation

Cell Side Potential Leak Path

Media Pack Sealant — A layer of high efficiency media seals the media pack into the cell sides. The media sealant prevents bypass leakage and damage to the media and separators during shipping and handling. By allowing slight movement of the media pack when the filter is jarred, the cushioning sealant helps prevent tears and punctures to the media.

Rigid construction and minimum depth make VariCel filters easy to install in all types of systems.

DUAL DENSITY MEDIA REDUCES OPERATING COSTS

VariCel media is manufactured with two layers of glass fibers: coarser fibers on the air entering side and finer fibers on the air leaving side.

AIRFLOW

COARSE FIBERS

Air entering side

Our dual density design allows FINER FIBERS dirt particles to be collected Air leaving side throughout the entire depth of the filter utilizing the full cleaning potential of the media. Maximum dust holding capacity extends the life of the filter, minimizing operating costs. The water resistant media can withstand intermittent exposure to water, making VariCel filters ideal for installations in humid areas or where the filters are exposed to moisture.

AstroCel® I HC High Quality HEPA Filter

● High air volume filter: 3000 m3/h ● Classified H12, H13 and H14 according to EN1822 ● Space saving design ● Saves energy in existing installations

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. ● Standard individually tested.

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.

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 and the 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, especially when local laminar flow work stations are operational in the room.

Laminar Flow Cleanrooms Basic Design and Operating Considerations

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.

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.

Basically, there are two types of laminar airflow cleanroom: a) Vertical downflow b) Horizontal crossflow

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,

Vertical Downflow In a vertical downflow cleanroom, air enters the room via filters in the ceiling surface and is exhausted via a perforated

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 at one 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

Arrestance Filters (Coarse Filters) in the range G1 - G4. Final pressure drop for certification is specified at 250 Pa maximum. Filters with an initial dust spot efficiency above 20% are classified as Efficiency Filters (Fine Filters) in the range F5 - F9. The final pressure drop for certification is set at 450 Pa maximum.

In 1993, the European Committee for Standardization, Technical Committee 195, Work Group 1 (CEN/TC195-WG1) established a new standard for general ventilation filters. With the introduction of this standard under document name EN 779, member countries of the European Union are obliged to issue their own national version of this standard within the existing framework of their own national standards organizations. For example, BS EN 779 in the U.K.

and DIN EN 779 in Germany. EN 779 is based on existing documents such as EUROVENT 4/5, and ASHRAE 52.1:1992, but is in fact more stringent than either of these standards. The standard incorporates a new system of classification for Coarse and Fine filters based on an average dust spot efficiency at a specified final pressure drop.

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 the basis for a future new standard. WG 1 has also expressed its intention to work in closer liaison with ASHRAE on this subject.

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.
