Nordfab® Automatic Blast Gates are utilized as energy saving devices in industrial dust extraction applications where continual extraction is not required and where manual control needs to be eliminated. NFES Auto Blast Gates feature laser welded seams - rolled ends and are operated by double-acting compressed air cylinders. The cylinders are controlled by electrically-connected solenoid to machines or a remote switch. Blast gates are constructed of galvanized or stainless steel metals. 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.
