- QF Manual Blast Gate
QF Manual Blast Gates are energy-saving devices allowing manual operation to shut off airflow from all machines that run intermittently, and are constructed of a cast aluminum body with a galvanized steel standard connection collar. The SS model is 100% Stainless Steel. SS Collars are fully welded to SS body. Body and blade are 12gauge.
- QF Manual Blast Gate NFMES
QF NFMES Manual Blast Gates are compact and easy to operate gates, constructed of galvanized metal with a special sealing device that reduces air loss and friction. Collars are located on the exterior side of each port and considered as air flow non-directional. They have a laser welded longitudinal seam and are spot welded to each side of the cast aluminum body. Body and blade are constructed with 18ga cast aluminum, and handles with 1018 carbon steel, Powder Coated. Ends have a rolled edge for easy connection to QF ductwork.
- SD Automatic Blast Gate
SD Auto Blast Gates are built for years of continuous use in the most demanding conditions. A heavy-duty cast aluminum body is encased in protective galvanized sheeting to safely shield fingers from moving parts. The SD Gates are operated by compressed air cylinders, controlled by electrically connected solenoid. 120V control circuit and 75psi minimum air pressure. Optional 24V DC or AC control circuits available. Single cylinder: 3″ to 8″. Two cylinders: 9″ to 22″. Collars are attached to the exterior to each side of the cast aluminum body, manufactured in Galvanized metal.
- QF Blast Gate NFES Automatic
NFES Automatic Blast Gates are operated by double-acting compressed air cylinders. The cylinders are controlled by electrically-connected solenoid to machines or a remote switch with a 120V control circuit and 75psi minimum air pressure. Optional 24V DC or AC control circuit available. Single cylinder is used for 3 to 8” diameters and 2 cylinders are used for 9 to 22” diameter. Gates are constructed of galvanized metal or Stainless Steel (optional), and a special sealing device that reduces air loss and friction in operation.
