ODD Size Designator
Odd size designators are an alpha numeric descrip-
tion. The first two digits specify the height whole num-
ber with an alpha designator specifying the height
fraction. The second two digits specify the width
whole number with an alpha designator specifying
the width fraction. And the last alpha designator
specifies the depth. If he height or width is less than
10 inches, use a 0 in front of the dimension.

Guide Specifications
1.0 General
1.1 High temperature separator style HEPA filters shall
be Alpha HT models as manufactured by Flanders.
1.2 Filter sizes, capacities and construction options
shall be as scheduled on the drawings.
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.
2.2 The filter pack shall be sealed into a (409 stainless
steel) (304 stainless steel) frame with a high tem-
perature silicone sealant rated for 500°F or a glass
pack sealant rated for 1,000°F in exhaust applica-
tions.
2.3 (A chlorastic silicone gasket) (a woven glass gasket)
shall be provided to seal the filter in the mounting
device (Gasket Seal). A silicone gel shall be provid-
ed in a channel on one side to seal the filter in the
mounting device. filters with silicone gel have a max-
imum service temperature of 390°F (Gel Seal)
3.0 Performance
3.1 Initial and final resistances shall not exceed the
scheduled values.
3.2 Alpha HT HEPA Filters shall have a minimum effi-
ciency 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. Each
filter shall be challenged with an approved nearly
monodispersed oil aerosol of 0.30 micrometer size.
Measure the upstream and downstream concentra-
tion of these particles with a light scattering pho-
tometer, determine the penetration and calculate the
efficiency.
3.3 Alpha HT Scan Tested HEPA Filters shall have a
minimum efficiency of 99.99% on0.30micrometer
particles when tested at rated capacity on a Q-107
Penetrometer in accordance with IEST-RP-CC-
001.3, Type C. The scan test shall consist of chal-
lenging 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 leak greater than .01% of the
upstream concentration at 100 fpm face velocity.
