Alpha 2000 High Capacity HEPA Filters

Model #: Contact Factory Bulletin: PB1402-0508

F O R E M O S T I N A I R F I L T R A T I O N

High Capacity Design The Alpha 2000 High Capacity HEPA filter is avail-able in a nominal 12” depth configuration. It is designed for optimum performance and low operat-ing costs in both new and replacement systems.

The Alpha 2000 saves space, energy, and material and labor costs with 40% more media area than the standard capacity Alpha Cell filter.

Save Space Alpha 2000 HEPA filters operate at 500 fpm (2000 cfm for a 24” x 24” size) at 1.35 inch w.g. clean pressure drop versus conventional Alpha Cell filters that operate at 250 fpm and .80 inch w.g. clean pressure drop.

Construction A popular construction option consists of 16 ga.

galvaneal frames and moisture-resistant microfine wet-laid fiberglass media folded over hemmed-edge low amplitude corrugated aluminum separators.

The filter pack is bonded to the frame by a fire-retardant urethane elastomer to provide a rigid leak-free assembly.

Save Energy Alpha 2000 filters in a conventional HEPA filter bank impose a lighter load on the fan when operated at conventional 250 fpm velocities during the life of the filters. The Alpha 2000 99.97% and 99.99% high capacity 24” X 24” X 11.5” filter has a clean pressure drop of 1.0 inch w.g. at 1500 cfm, compared to standard Alpha Cell filters with a clean pressure drop of 1.50 inch w.g. at the same air flow.

Save Replacement Material and Labor Costs Savings are significant with high capacity Alpha 2000 filters. They operate at lower velocities and provide life cycles up to three times the life of standard capacity filters. Savings are achieved in replacement materials and labor costs as a result of fewer filters.

Important Features

• Efficiencies are 99.97% and 99.99% on 0.30 and 99.9995% on 0.12 micrometer particles.

• High capacity Alpha 2000 filters can reduce the filter bank size

• Corrugated aluminum separators stabilize the moisture-resistant media pack (separator style)

• Available as a separatorless media filter with a self-supporting media pack (*Pureform)

• Available in a variety of frame materials in gasket or fluid seal design.

Separator or Separatorless Flanders manufactures both conventional Separator Style and Pureform Separatorless HEPA Filters. To make a Separator Style filter, the media is folded over corrugated aluminum separators with hemmed edges to separate the pleats in the filter pack. Flanders manufactures its own fil-ter media, enabling it to develop a unique manufacturing process for the production of Pureform Separatorless HEPA Filters. In one manufactur-ing operation, Flanders produces a self-supporting and self-separating Pureform Media Pack.

The Pureform Filter offers many advantages over conventional Separator Style HEPA Filters:

• More usable media area for longer service life because of higher dust holding capacity

NOTE: The pressure drop for fluid seal (Separator or Pureform) and scan tested Pureform filters will be approximately 15% higher.

1.0 General

1.1 Alpha 2000 HEPA filters shall be extended media

(separator type) (Pureform separatorless type) filters as manufactured by Flanders.

1.2 Filter sizes, capacities and construction options shall

be as scheduled on the drawings.

1.3 Filters shall be (UL 900 Class 1)(UL586) listed.

2.0 Filter Construction

2.1 The filter pack shall be constructed by pleating

a continuous sheet of non-woven water-resistant fiberglass media around hemmed-edge corrugated aluminum separators. (or) The filter pack shall be constructed by pleating a continuous sheet of formed, corrugated medium so that the pack is self-supporting without the use of spacers of any kind, including separators, tape strings, adhesives or strips of media.

2.2 The filter pack shall be sealed into a (galvaneal) 409

stainless steel) (304 stainless steel) (particle board) (fire-retardant particleboard) (fire-retardant plywood) frame with a fire retardant(polyurethane foam) ( solid urethane) sealant. (Steel frames shall be 16 ga.)

(Wood frames shall be 3/4” thick.)

2.3 (A 40-durometer closed-cell neoprene gasket) (Silicone jel in a channel) shall be provided on one or more sides to seal the filter in the mounting device.

3.0 Performance

3.1 Initial and final resistances shall not exceed the

scheduled values.

3.2 Alpha 2000 HEPA Filters shall have a minimum

efficiency of 99.97% on 0.30 micrometer particles when tested at rated capacity on a Q-107 Penetrometer in accordance with IEST-RP-CC-001.3, Type A. Measure the upstream and down stream concentration of these particles with a light scattering photometer, determine the penetration and calculate the efficiency.

3.3 Alpha 2000 Scan Tested HEPA Filters shall have a

minimum efficiency of 99.99% on 0.30 micrometer particles in accordance with IEST-RP-CC-001.3, Type C. The scan test shall consist of challenging the filter with a high concentration of an approved oil aerosol or PSL Spheres. Utilizing a photometer or particle counter, the media pack and the pack-to- frame seal shall be scanned to insure that there are no leaks greater than .01% of the upstream concentration at 100 fpm face velocity

Frame Materials: Alpha 2000 Filters are available in a variety of wood and metal frame materials such as par-ticle board, plywood, galvanized steel and stainless steel.

Gasket and Fluid Seal: The standard gasket seal is 0.75” x 0.25” neoprene for installation on either the upstream, downstream or both sides of the filter. The standard Fluid Seal is Flanders Blu-Jel® Seal which is a two - part silicone material suitable for temperatures up to 390°F.

Faceguards (Optional): Faceguards are used to protect the filter media from mechanical damage. The typical faceguard material is expanded aluminized steel. Galvanized 4 x 4 mesh welded wire and Type 304 stainless steel are also available.

Underwriters Laboratories Qualification: Alpha 2000 Filters are either UL900 Class 1 or Class 2 listed depending on materials of construction.

UL 900 Class 1 — Flanders HEPA Filters are UL 900 Class 1 rated except those filters manufactured with non-fire-retardant wood frames. Upon request, the filter will have a stamp indicating compliance with UL 900 Class 1.

UL 586 — UL 586 is typically required for Nuclear Grade HEPA Filters. Many of the Flanders non-Nuclear HEPA Filters meet the requirements of UL 586. To be listed under UL 586, filters must be submitted to Underwriters Laboratories for extensive testing including spot flame and environmental exposure to heated air. Upon request, a numbered UL 586 label certifying that the filter meets Standard 586 can be applied to the filter (maximum size is 24” x 30”).

Banks: Alpha Frames are designed for Alpha 2000 filters in built-up filter banks. Each filter is secured in the frame with four bolt-type fasteners that either compress the gasket or press the knife edge into the gel in the filter channel to maintain a leak-tight seal.

Surelock HEPA Filter Housings are recommended for side-access applications. The filters are sealed in place with either spring-loaded swing arm assemblies or a locking mechanism. The swing arm assemblies or locking mechanism either compress the gasket or press the knife edge into the gel in the filter channel to maintain a leak-tight seal.
