High-temperature 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 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. Sealant Types Two types of sealants for high-temperature HEPA filters are offered. SiliconeSealant 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. GlassPackSealantForExhaustAirOnly 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.

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.
