The Blow Thru Rotary Airlock Valve is used in pneumatic conveying applications only, both positive pressure and vacuum. Instead of a typical outlet, blow thru rotary airlocks include two ports on the sides of the valve near the bottom. The conveying line pipe connects directly to the valve, with the air stream flowing through the rotor pockets.

This design is very efficient, and works well on materials that tend to hang up in the rotor pockets. However, this valve is not recommended on abrasive products as the vanes will quickly wear. This unit is also very helpful in applications that have height limitations.

Convey line adapters are provided to suit the application.

Sizes: 6, 8, 10, 12 and 16 inch
