DCS Rotary Airlock Feeder

November 16, 2012

The Dust Collector Series (DCS) rotary airlock feeder is suited for general use under dust collectors, cyclones, and hoppers. With standard features normally considered heavy-duty, these feeders boast eight-blade rotors, precision machining, and rugged cast iron housing for efficient operation. In a case where pressure differential exists, such as when feeding pneumatic conveying lines, the heavy-duty series rotary airlock feeder is best suited for feeding the material accordingly. These particular airlocks maintain the highest level of performance for an extended period of time. The Quick-Take-Apart Series (QTA) rotary airlock feeder is made for applications where frequent removal of the valve internals is required. This valve permits tool-less removal of the rotor and end plate as one piece, eliminating the time-consuming step of “gapping” the rotor during re-assembly. When encountering alumina, coke, fly ash, glass frit, and other highly abrasive products, the ceramic series rotary airlock feeder sustains its durability and achieves at least 3-5 times longer life compared to chrome and Ni-hard valves. A high-performance, thick wear layer of alumina ceramic coating maintains the valve’s precision tolerances longer.
