FOREMOST IN AIR FILTRATION

General

Flanders manufactures metal-frame separator-style
HEPA filters for applications with high-temperature
requirements up to 1,000°F (540°C) for exhaust air
only and 500°F (260°C) for supply air. High-tem­perature filters are available with either a gasket or
fluid seal. Filters with Blu-Jel
maximum service temperature of 390°F (199°C)

® Fluid Seal have a

HEPA Filters

Each HEPA filter has a minimum efficiency of

99.97% on 0.30 micrometer size particles when
tested at rated capacity on a Q-107 Penetrometer.
Each filter is challenged with an approved nearly
monodispersed oil aerosol of 0.30 micrometer size
and by measuring the upstream and downstream
concentration of these particles with a light scatter­ing photometer, the penetration can be determined
and the efficiency can be calculated.

Scan Tested HEPA Filters

Each Scan Tested HEPA filter has a minimum effi­ciency of 99.99% on 0.30 micrometer particles.
Scan testing is in accordance with Section 6.2 of
IEST-RP-CC034.1, HEPA and ULPA Filters Leak
Tests. In the scan test, the filter is challenged with
a high concentration of an approved oil aerosol or
PSL (Polystyrene Latex Spheres). The media pack
and pack-to-frame seal is scanned using a pho­tometer or particle counter to insure that there are
no leaks greater than .01% of the upstream con­centration at 100 fpm face velocity. Scan testing is
only available for the 500°F model.

High Temperature HEPA Filters

Sealant Types

Two types of sealants for high-temperature HEPA
filters are offered.

Silicone Sealant

This is a high temperature (RTV) silastic-sealant sil­icone compound rated for continuous service up to
500°F(260°C). NOTE: This high-temperature
sealant is not UL 586 approved.

Glass Pack Sealant For Exhaust Air Only

The glass pack seal is rated for continuous service
up to 1,000°F(540°C) in exhaust air applications
only. It is a mat of submicron glass fibers that cre­ates a seal when compressed between the filter
pack and filter frame. The glass packing is not an
adhesive seal but a mechanical seal that functions
much as the glass fiber medium of the filter itself.

NOTE: Due to the possibility that the glass pack
may shed glass fibers, the glass pack sealant
should be used for exhaust systems only.

Odd size designators are an alpha numeric descrip­tion. The first two digits specify the height whole num­ber 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

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 tem­perature silicone sealant rated for 500°F or a glass
pack sealant rated for 1,000°F in exhaust applica­tions.

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 provid­ed in a channel on one side to seal the filter in the
mounting device. filters with silicone gel have a max­imum service temperature of 390°F (Gel Seal)
