Designed to meet the stringent requirements of HEPA filter applications, AstroSeal Type S housings are engineered to perform reliably even in the toughest environments. The innovative design ensures uniform and constant pressure against the sealing surface of the HEPA filter.

AstroSeal Type S is built with industrial welded construction for reliable performance up to 10″ positive or negative pressure (optional construction up to 20″ w.g.). Standard 2″ deep access doors have internal welded reinforcement and a precise pin type hinge. A 1-1/2″ wide neoprene rubber gasket surface forms the proper seal with “finger pressure” locking knobs.

The Type S is available in two models: gasket seal housings with a rugged, crank lock mechanism, and a gel seal model with a knife edge sealing surface. AstroSeal Type S housings are available with a 2″ or 4″ wide prefilter track. Blank off panels are provided to prevent prefilter bypass.

Options include double door accessibility, insulation, pressure testing, static taps, resistance gauge, and test port.
