AIRLANCO airlocks are available in customized fabricated and machined models for pneumatic systems, gravity feeds and volumetric discharge devices. Fabricated models handle grain, food, feed and dust collection where pressure differentials are 20 in. of water column or less; urethane wipers provide a tight fit between fabricated rotors and housings. Machined airlocks have cast housings and are designed for higher pressures as well as difficult and abrasive materials; rotor-to-housing fit is 4- to 6-thousandths of an inch.
