Airsweeps Guarantee Flow

Airsweep Material Flow Systems provide on-demand flow of even the toughest materials by eliminating bridging, ratholes and build-up. Each powerful pulse of the Airsweep nozzle directs a high-pressure/high-volume, 360-degree burst of compressed air between the material and vessel wall to lift and sweep stagnated material back into the flow stream. The nozzle design (U.S. Patent 6,237,893) ensures an immediate, dust-tight, reseal after each pulse, preventing clogging or material feedback.

Airsweep nozzles are available in multiple sizes, featuring design, mounting and material of construction options to suit virtually any vessel, process and material.

Airsweep Cutaway View

Powerful, quick, pulses of compressed air forces the Airsweep valve open, directing high-pressure, high-volume bursts of air between the inside vessel wall and the stored material, initiating and maintaining steady flow.  The patented, retracting, nozzle design (U.S. Patent 6,237,893) ensures an immediate reseal after each pulse to prevent nozzle clogging or material feedback and eliminate frequent maintenance.
