Airlocks, Feeders, & Screw Conveyors

REES Model RVC Rotary Airlock

REES airlocks are used in low-pressure air systems to feed high volumes of bulk material from cyclones and filters to transfer systems and bins. Flexible rubber-tipped rotors help reduce the chance of mixed material plugging and allow for wiper blade replacement. The fabricated steel housing and chain-drive components are built to withstand continuous heavy-duty on-line operation.
