Frame Materials
Alpha 95 Filters are available in a variety of wood and metal frame materials such as particle board, plywood,
galvanized steel and stainless steel.
Gasket and Fluid Seal
The standard gasket seal is 0.75” x 0.25” neoprene for installation on either the upstream, downstream or
both sides of the filter.
The standard Fluid Seal is Flanders Blu-Jel® Seal which is a two - part silicone material suitable for tem-
peratures up to 390°F.
Faceguards (Optional)
Faceguards are used to protect the filter media from mechanical damage. The typical faceguard material is
expanded aluminized steel. Galvanized 4 x 4 mesh welded wire and Type 304 stainless steel faceguards
are also available.
UL Listings
Alpha 95 Filters are either UL900 Class 1 or Class 2 listed depending on materials of construction.
Holding Frames and Housings
Alpha Frames are designed for Alpha 95 filters in built-up filter banks. Each filter is secured in the frame with
four bolt-type fasteners that either compress the gasket or press the knife edge into the gel in the filter chan-
nel to maintain a leak-tight seal.
Surelock HEPA Filter Housings are recommended for side-access applications. The filters are sealed in
place with either spring-loaded swing arm assemblies or a locking mechanism. The swing arm assemblies or
locking mechanism either compress the gasket or press the knife edge into the gel in the filter channel to
maintain a leak-tight seal.
