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 separa-
tors. 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 operat-
ed 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, com-
pared 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 stan-
dard capacity filters. Savings are achieved in
replacement materials and labor costs as a result of
fewer filters.

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 separa-
tors with hemmed edges to separate the pleats in the filter pack. Flanders manufactures its own
filter media, enabling it to develop a unique manufacturing process for the production of Pureform
Separatorless HEPA Filters. In one manufacturing operation, Flanders produces a self-support-
ing 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
• Reduced cost of ownership because of longer service life
• Maximum utilization of the media
• Can handle some harsh environments which may attack aluminum separators
• Media pack can be incinerated
• Media is 28 mils thick, which is significantly thicker than conventional 15 mil media used
in Separator Style HEPA Filters

Frame Materials: Alpha 2000 Filters are available in a variety of wood and metal frame materials such as parti-
cle 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 stain-
less 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 fil-
ter 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.

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 corru-
gated 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 spac-
ers 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) (parti-
cle 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 mount-
ing 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 parti-
cles 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 pene-
tration and calculate the efficiency.
3.3 Alpha 2000 Scan Tested HEPA Filters shall have
a minimum efficiency of 99.99% on 0.30 microm-
eter 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
