Airlocks and Diverter Valves

Mac Process believes that the more knowledge you have, the more efficient and effective your airlock selection will be.

What is a rotary airlock? A rotary airlock (also known as a rotary feeder or valve) consists of a housing, a blade and shaft assembly, two end plates, seals and bearings, and a motor and drive assembly. The assembled rotary airlock acts as a rotating paddle wheel inside the housing, moving the dry bulk solid from the top of the rotation (inlet) to the bottom rotation (discharge.)

An airlock acts as a rotating barrier between its IN and OUT ports, impeding the flow of air through its close fit blades and housing, while moving pockets of material in a continuous rotating motion. Airlock performance relates directly to the material being handled and the applications. Our sales representatives and engineers are experienced at matching the right airlock to your specific application need.

Airlocks play an important role in material conveying and processing systems. An improperly applied airlock can lead to poor system efficiency, extra maintenance, product degradation, equipment wear and replacement, and lost production due to process shutdowns. The annual cost of any of these issues can easily exceed the cost of the equipment itself.
