Why choose a Prater Rotary Airlock?

After years of engineering and manufacturing rotary airlocks, we consider ourselves proven experts on the various rotary airlock and valve designs available to our customers. We understand that temperature, pressure, size and construction plays a very significant role in processing various materials which is why all of our rotary airlock valves are carefully machined for those unique specifications. Each of our rotary airlocks can be individually customized to your exact processing specifications to ensure optimal, reliable and worry-free operation that meets your precise needs.

Our airlocks have an innovative larger vane pocket design that allows up to 50% more volume which enables the rotor to run at lower speeds than other manufacturers’ rotary airlock and valve feeders. Pair this with our exclusive self-adjusting packing glands and you have a rotary airlock valve that provides minimum air leakage, a longer life, less maintenance and a higher return on your investment.

Other standard features such as our precision casting, CNC machining, compact design, and universal mounting flanges allow for a versatile material handling rotary airlock valve product that can fit virtually every existing bolt hole pattern and replace any existing rotary valve.
