Inner Seal Housings are designed to hold single or multiple stages of filtration in side or bottom access configurations. Housings are constructed of 16GA Galvanized or Stainless Steel and are intermittently welded and caulked air tight. Housings have welded corner gussets to ensure a rigid assembly. Access doors are hinged and fitted with positive pressure trip latches. Doors are fitted with interior gasket to seal against aluminum tracks to prevent air by-pass around the periphery of the filter bank. Filter housings are rated to +/- 6”WG and 0.5” leakage at 125% of standard rated flow.

Series of gasketed aluminum tracks are available for different filter arrangements.
