This POSITIVE AIRLOCK feeds grain continuously or intermittently into a positive-pressure conveying pipe, where the material is carried away by air. Widely used as a feeder in flour, bran, starch, grain, feed, sugar, chemical, and plastic granular plants, it ensures efficient material transfer under pressurized conditions. An axial discharging groove beneath the casing supports smooth conveying operations and enhances system integration.
