Installation Considerations

Precision Pak bag filters may be installed in Flanders Type 9 Holding Frames, K-Trac Filter Framing Modules, Sureseal Side Access Housing or in simi- lar existing hardware.

Type 9 Holding Frames are riveted together to form a bank and may be installed for upstream or down- stream service. K-Trac Filter Framing Modules are especially suitable for medium to large built-up filter banks. Smaller systems and systems with minimum upstream access space are best served using Sureseal Side Access Housings.
