Sealant Types  
Two types of sealants for high-temperature HEPA  
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)  
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.  
HEPA Filters  
Glass Pack Sealant For Exhaust Air Only  
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.  
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.  
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.
