DC20 Dust Cannon

Dust Suppression for Medium-Sized Sites

The Air Spectrum DC20 Dust Cannon is a dust suppression system designed to control airborne dust across construction, demolition, recycling, quarrying and industrial applications. Combining a compact footprint with wide-area coverage, the DC20 provides reliable, targeted dust suppression wherever effective airborne particulate control is required.

Our range of dust cannons creates a fine mist of water droplets which is then directed forwards by a high-flow fan. On the DC20, the water mist can be projected up to 20 metres, depending on the unit’s placement and local wind conditions. As the mist travels through the air, it binds with airborne dust particles, causing them to fall safely to the ground and helping to maintain cleaner, healthier working environments.

With a maximum coverage area of up to 1,170 m² per unit, the DC20 is an ideal solution for medium-sized sites that require consistent dust control across a wide working area. A key feature of the DC20 is the high winch mast that extends the head vertically to ensure maximum coverage.

Wide Coverage, Greater Flexibility

The DC20 is engineered to maximise coverage while remaining simple to operate. The cannon head can automatically oscillate through up to 335°, allowing the unit to distribute mist across large areas without the need for repositioning alongside the extendable mast. This makes it particularly effective for stockpiles, processing areas, loading bays and material handling operations where dust is generated across multiple locations.

The cannon head can also be tilted between -30° and +10°, enabling operators to fine-tune the throw angle to suit different site layouts and applications. Together, the oscillation and tilt functions provide exceptional flexibility and ensure dust is suppressed precisely where it is generated.

Whether used as a standalone unit or integrated into a wider dust management strategy, the DC20 delivers dependable performance with efficient water usage and low maintenance requirements.

Dust Cannon vs Rotary Atomiser – Which Is Right for Your Application?

With a working range comparable to the Air Spectrum Rotary Atomiser PRO, the DC20 offers excellent site coverage while using a different method of producing and projecting mist.

The DC20 Dust Cannon uses precision misting nozzles to generate a fine water mist, which is then propelled forwards by a powerful high-flow fan. This creates a concentrated mist plume that is highly effective at capturing airborne dust around crushing, screening, demolition, recycling and bulk material handling operations.

The Rotary Atomiser PRO, by comparison, uses centrifugal atomisation technology to spin water into an ultra-fine mist before projecting it with a vortex fan. This makes it particularly well suited to applications such as odour control, and dust control situations where an exceptionally fine, adjustable mist is required. The size of the microns of water produced are different with a Rotary Atomiser and a Dust Cannon, with RA’s producing a finer, smaller micron size of mist.

Ideal Applications
