Available at Control Hire, our L3 Dust Suppression Lance is a compact, easy-to-use solution for close-range dust suppression. Operable without the use of a turbine or fan, allowing a mobile approach close to the dust source. Depending on the needs of the situation, the spray action can be narrow and flat, fan-shaped, or cylindrical. Need dust suppression hire equipment for your site? Get in touch with our team.

How Droplet Size Affects Dust Suppression
The optimal droplet size for effective dust suppression is typically in the range of 50–60 microns. This precise size is ideal for capturing and binding with dust particles suspended in the air, increasing the chances of collision and adhesion — especially with fine particulates such as Respirable Crystalline Silica (RCS).
If the droplet diameter is much greater than the dust particle, the dust simply follows the air streamlines around the droplet, reducing the chance of impact and capture. On the other hand, droplets that are too small can evaporate before they make contact.
Control Hire’s dust suppression systems are engineered to consistently produce this optimal droplet size, ensuring maximum dust capture efficiency, better air quality, and compliance with Australia’s stringent WHS regulations.
