QF SD Automatic Diverter Valve

Nordfab manufactures ducting for use in dust, mist, and fume collection systems.

Our Standard-Duty (SD) diverter is a light air diverter that doesn’t sacrifice power. It exhausts air only from industrial machinery while it is operating, which increases suction at all other points in the system and reduces the amount of heated or cooled air exhausted from the work area, saving on ventilation costs.

Built for years of continuous use in the most demanding conditions, our SD Auto Diverter carries a one-year warranty. Standard unit is heavy duty construction of 14ga galvanized steel or 304SS with bolted seams (optional 316SS or carbon steel). Heavy duty flange bearings and rubber seal in 14ga steel door. Rubber seal is 1/4” thick polymer compound #AB-3205. Auto Diverter Valves have single magnetic cylinders with galvanized or SS body and steel rod. Solenoid has plastic housing.

Minimum 75psi.
45º angle only.
Available with flanged ends in diameters up to 13", and other various end types
