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.
