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-tem-
perature filters are available with either a gasket or
fluid seal. Filters with Blu-Jel
® Fluid Seal have a
maximum service temperature of 390°F (199°C)
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 scatter-
ing photometer, the penetration can be determined
and the efficiency can be calculated.
Scan Tested HEPA Filters
Each Scan Tested HEPA filter has a minimum effi-
ciency 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 pho-
tometer or particle counter to insure that there are
no leaks greater than .01% of the upstream con-
centration at 100 fpm face velocity. Scan testing is
only available for the 500°F model.
Sealant Types
Two types of sealants for high-temperature HEPA
filters are offered.
Silicone Sealant
This is a high temperature (RTV) silastic-sealant sil-
icone 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 cre-
ates 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.
