Rotary Air Lock


rotary air lock

The Airex Industries line of rotary airlocks are designed to control the flow of discharge material from a dust collector or other type of process by maintaining an air seal.

A motor driven paddle wheel rotates material from the top of the housing to the bottom.

How it Works

The discharge falls from the hopper into the rotary airlock. Paddle wheels with rubber extensions to keep the system hermetically sealed collect the discharge. A motor drive rotates the paddle wheels at a specified speed and eventually the particles are evacuated from the bottom of the system without breaking the air seal.
