The Aerostar Series 400 pleated air filter utilizes a state of the art 100% synthetic media to achieve exceptionally high levels of efficiency with the lowest resistence to air flow available. The media is laminated to an expanded metal grid on the air exiting side to provide exceptional strength during installation. The media support grid prevents fluttering and maintains pleat uniformity for optimum performance. The filter pack is enclosed in a heavy-duty moisture resistant die-cut frame that will not warp, crack or distort under normal operating conditions.
The 1′ and 2″ depth filters handle air velocities up to 500 fpm; 4″ depth filters up to 625 fpm. Aerostar Series 400 pleated air filters are designed for use in commercial buildings, hotels, industrial filtration, airports, schols, and universities, or any application desiring higher levels of air filtration to protect occupants from airborne irritants and protect cooling coils, ductwork, and other components of the HVAC system from dust and dirt.
