Blast gates are used as energy saving devices for industrial dust extraction where continuous extraction is not always needed and where manual control needs to be eliminated. Nordfab’s 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. Gates are constructed of galvanized steel. A special sealing device reduces air loss and friction in operation.

120V control circuit and 75psi minimum air pressure. Optional 24V DC or AC control circuit available.

Single cylinder: 8″. Two cylinders: 9″ to 22″.

Nordfab can assist customers in designing a blast-gated system, taking into account flow dynamics that will be affected by blast gates. While blast gates can be used to effectively utilize an undersized filtering system, they can also destroy the flow if not properly placed.
