Blast Gate NFES Automatic

Automatic energy saving blast gates operated by double-acting compressed air cylinders. Cylinders are controlled by electrically-connected solenoid to machines or remote switch. Gates are constructed of galvanized metal or SS(optional) and a special sealing device that reduces air loss and friction in operation. Available in sizes 4" dia=22" dia, 120V control circuit and 75psi minmum air pressure. Optional 24V DC or AC control circuit available. 
APPLICATION: Gates are used as energy saving devices for industrial dust extraction where extraction is not always needed and where manual control needs to be eliminated. 
Single Cylinder:  3"-8". Two Cylinder: 9"-22"
All auto blast gates have cylinders w/metal body and steel rod. Solenoid has plastic housing.
