U.S. Air Filtration provides a complete line of rotary airlocks suitable for air lock applications ranging from gravity discharge of filters, rotary valves, cyclone dust collectors, and rotary airlock storage devices to precision feeders for dilute phase and continuous dense phase pneumatic convey systems.  Rotary Airlock Feeders/ Rotary Airlock Valves are used in pneumatic conveying systems, dust control equipment, and as volumetric feed-controls to maintain an even flow of material through processing systems.  The basic use of the rotary airlock feeder is as an airlock transition point, sealing pressurized systems against loss of air or gas while maintaining a flow of material between components with different pressure.  Rotary Airlock Valves are also widely used as volumetric feeders for metering materials at precise flow rates from bins, hoppers, or silos onto conveying or processing systems.

A rotary valve is of no use by itself.  Rotary airlock, airlocks, and rotary valves are useful as one component in a bulk or specialty material handling system.  Rotary Airlock Feeders have wide application in industry wherever dry free-flowing powders, granules, crystals, or pellets are used.  Typical materials include:  cement, sugar, minerals, grains, plastics, dust, fly ash, flour, gypsum, lime, coffee, cereals, pharmaceuticals, etc...
