Airlock Genius – Heavy-Duty Rotary Airlocks for Demanding Applications
The Standard Heavy-Duty Airlock from Airlock Genius combines the best features of multiple airlock series into one advanced design engineered for superior sealing, durability, and performance. Available in 6” to 16” valve sizes, each unit features precision CNC-machined components with a nominal gap of just 0.002”–0.004”, ensuring tight tolerances and reliable operation in high-pressure and high-temperature applications up to 700°F.
Built with cast iron or stainless steel construction, our airlocks accommodate both square and round flanges and include a wide throat opening for maximum pocket filling efficiency. The innovative Hybri-Seal® assembly—a hybrid cartridge with Teflon and packing seals—enhances sealing performance up to 10× better than standard designs. Outboard sealed bearings and polished rotor shafts further extend seal life and minimize maintenance.
Designed using advanced engineering analysis, each airlock is equipped with a high-quality TEFC powertrain, chain drive, and eight-vane mild steel rotor for rugged reliability. With a choice of custom options and Hybri-Seal® cartridge types, Airlock Genius provides the right solution for every bulk material handling, dust collection, and pneumatic conveying application.
To summarize, the 8″ Rotary Airlock Valve (HDUCI Series) is engineered for heavy-duty industrial performance, delivering reliable airlock sealing and smooth material discharge in dust collection and pneumatic conveying systems. Built with durable cast iron construction, this valve provides exceptional wear resistance, longer operational life, and consistent performance under continuous demanding conditions.
With a capacity of 0.31 cu ft/rev, this 8-inch HDUCI rotary valve ensures accurate material metering with minimal air leakage, helping maintain system efficiency, product quality, and airflow stability. It is ideal for handling powders, pellets, granules, sawdust, cement, grains, and similar dry bulk solids across multiple industries.
