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
