Powder Flow Aids - Airsweep Systems Overview

Typical Airsweep® System

A typical Airsweep system consists of strategically-located Airsweeps, high-flow solenoid valves, electronic sequence controller and air receiver.

The system can operate independently or can easily integrate with other equipment or automation systems. Based upon flow requirements, system is set to sequentially pulse bursts of high-velocity air along the container wall. Up to an 8-foot diameter of material is dislodged with each pulse, promoting steady outflow.
