This AIRLOCK is typically installed beneath cyclones or jet filters and is constructed from specially cast iron to ensure reliable sealing performance. It is designed for discharging mill stock and filter dust in food processing environments, and also serves to feed materials such as grain, break stock, semolina, flour, and similar products from pneumatic conveying lines. Its robust build supports consistent operation and minimizes air leakage in high-demand milling systems.
