Standard Duty Rotary Airlock Valves

The Standard Duty Drop Thru Rotary Airlock is a less expensive alternative to the Heavy Duty Airlocks, and is ideal for applications where a more robust valve is not required.  The Standard Duty Airlock is used in gravity flow or low-pressure differential applications such as on the bottom of a dust collector, surge hopper or silo, and are used for handling dry, free flowing, non-abrasive materials.  These units are precision machined for tight tolerances, as with all of our rotary airlocks, to insure minimal air leakage.  All standard duty airlocks are cast iron with a mild steel closed end rotor.  Both round and square flange units are available in the following sizes:  6, 8, 10 and 12 inch.
