Dust is a globally recognized problem with dust formed in the process of work activities now recognised as a significant contributor to ill-health. 

As a means of control water-suppression reduces dust clouds but needs to be applied correctly and throughout the duration of the work activity to be effective.

Traditional water-jet dust suppression systems generate water droplets with typically a 1000 micron average diameter; these large droplets are simply not able to capture the much smaller - but troublesome – dust particles which typically have a circa 80 micron diameter.  Furthermore water-jets tends to pass through the dust cloud and produce high levels of residual moisture and water pooling on the ground.

Dust Fighter DF Smart Misting Cannon

DF Ecology has developed a water-mist dust suppression system that is an improvement over conventional jets or water-sprays. 

The Dust Fighter (DF) Smart is a high capacity misting fan which produces finely divided “Nebulized” water droplets in the size range 40-120 micron diameter.  At this size they can easily combine themselves with dust particles of similar dimensions and precipitate them out of the air. 

Moreover because water-mists “float” more than a conventional spray it covers and envelops the dust cloud more effectively.

The DF Smart also uses water more economically.

 The throughput of water can be adjusted to suit the application, and the smaller droplet size which the DF Smart generates reduces pooling on the ground.

As with all our equipment the DF Smart is “roll up, plug in, and switch on” requiring only connection to 110v power and a water supply.  The DF Smart can also be used for cooling purposes, or without water misting simply as a high capacity ventilator.

Dustfighter DF Mini - Misting Unit

It's not always practicable to have equipment constantly connected to a water supply.

The DF Mini offers a good solution to this with an integral tank which allows operation for several hours between refill (in typical use).

DF Mini is also suitable for odour control; the odour-agent can be dosed direct to the water tank at time of refill, and the machine delivers a fine mist to the surrounding area. 

Tank refill is easy - through the blue filler cap (pictured).

DF Mini is intended for applications indoors.  Unlike most misting systems the DF Mini does not utilise a fan to deliver the mist; this makes it particularly useful where users don't want complications from a jet of air disturbing the workplace.

Its telescopic mast, the tilt facility of the mist head, and its integral pump allow a fine water mist to be delivered up to 8 metres and - depending on mist nozzles selected - it will run for up to 5 hours between refill.

Because of a passing resemblance to a film character of the 1990's it has been nicknamed "Dustfighter Johnnie 5" by our staff.

Vortex 440 Misting Cannon / Odour Suppressant

An alternative to the DF Mini is the Vortex misting unit which also has an integral water tank and is equipped with a fan to propel the water mist; so as well as dust and odour control the Vortex is useful for cooling purposes, and (when used without water) simply as a ventilator.

The Vortex runs off a standard 110v supply, and draws 10 amps.

It is simply wheeled into place - ideal for indoor and close-proximity outdoor work.

It generates mists with a small droplet size in the range 5 - 30 microns which minimises pooling.

This is a "roll-up, plug-in, switch-on" product.
