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 or gas 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.

Features and Benefits

  • Check Check
    Advanced Material Activation Technology

    AirSweep® systems deliver precise 360-degree bursts of compressed air or gas, activating material over a wide area without vibration or structural stress. This eliminates hang-ups and blockages in bins, hoppers, chutes, and silos – ensuring smooth, reliable flow.

  • Check Check
    External Installation for Easy Maintenance

    Designed for accessibility, AirSweep units are mounted entirely outside the vessel. This simplifies installation, reduces downtime, and makes ongoing maintenance safe and hassle-free – no need to enter confined spaces.

  • Check Check
    Versatile and Retrofittable Design

    AirSweep can be easily retrofitted to most systems, offering a flexible solution across industries. Its compact, high-temperature-resistant design (up to 482°C) makes it ideal for both new installations and upgrades.

  • Check Check
    Available in Various Materials of Construction

    AirSweep are available in carbon steel, 304 stainless steel, and 316 stainless steel. Other materials available upon request.

Proven Results Across Industries

AirSweep® is trusted worldwide in industries like mining, food processing, cement, chemical manufacturing, and bulk solids handling. Its proven performance helps companies eliminate downtime, reduce manual cleaning, and improve process efficiency.

Energy Efficient

AirSweep® delivers precise, short bursts of air only when needed, using less energy than traditional flow aids like vibrators or air cannons. This targeted activation minimises air consumption while maximising flow efficiency.

Why Choose AirSweep Over Traditional Flow Aids?

Unlike vibrators or fluidisers, AirSweep® targets material directly without damaging vessels or compacting product. Its non-intrusive design avoids material degradation and eliminates unnecessary wear and tear.
