16 gauge aluminized steel construction 2” pre-filter and 12” box style standard construction Lever locking mechanism to lock hepa filter Bolt on doors Aluminized Steel Extends Life, Enhances Appearance Standard material of construction is 16 gauge aluminized steel selected to provide superior corrosion and heat resistance resulting in longer product life. Appearance is also enhanced compared to galvanized steel construction. The housings are supplied with two bolt-on doors. The doors are pin type and crossbroke to withstand positive or negative pressure. They are fully gasketed with a closed cell neoprene gasket for an air tight seal. The doors are removable with easy turn hand knobs. HEPA Lock housings are equipped with a 1-1/2" outer flange for easy field connection to ductwork. Air Tight Sealing Mechanism Prevents Bypass The locking mechanism is operated by overcenter type clamps which force the filters against the channel grid system on the downstream side of the unit. The spring loaded mechanism maintains a positive pressure of 600 foot-pounds per filter. Standard units are designed for up to 5" W.G. pressure, positive or negative. Minimum Depth Saves in Line Space Overall depth is only 26" in direction of air flow with no upstream or downstream access required. The housings accommodate 5-7/8" or 11 1/2" deep HEPA filters with a downstream gasket. The units are equipped with a track to hold 2" or 4" pre-filters.
