HEPA Holding Frame

The AstroFrame filter holding frame is specifically designed for the built-up AstroCel High-Efficiency Particulate Air (HEPA) filter banks.

Each frame is seam-welded to deliver maximum enclosure integrity. Each features four removable latches constructed to produce sealing pressure with the turn of a bolt.

Suggested Specifications

Furnish and install HEPA filters and permanent galvanized (304 stainless steel) steel holding frames as shown on the plans and listed in the equipment schedule. The AstroFrame holding frames are factory-drilled for convenient assembly into banks. The contractor will apply caulking compound between the frames before riveting them into assembled banks. Each frame will be fitted with four bolt type latches, one at each side, to seat each filter firmly against the internally flanged surfaces of its holding frame.

A flat, wide surface sealing flange will be provided for gasket seal filters and knife-edge flange for gel seal filters. Each frame shall be constructed from 14-gauge galvanized steel (304 stainless steel), 13½″ in depth.
