BossTek has introduced a new model to its atomised mist cannon range that suppresses indoor particulate emissions for industries such as raw material handling

The compact DustBoss® DB-10 is engineered for enclosed working environments, with the manoeuvrable unit providing excellent suppression in a compact, portable design, the company says. The outcome is effective airborne particle control with fewer emissions, less standing water and a safer, more compliant workplace.

“Our customers are well-acquainted with our technology, but before the DB-10, the smallest machine could nearly cover a football field, which is far too powerful for most indoor applications,” Mike Lewis, Dust Control Specialist at BossTek, says. “Our first customer to use the DB-10 was a demolition contractor removing dusty drywall, plaster and tile containing potentially hazardous materials. These all produce highly regulated dust emissions. We worked with them to create a unit best suited to their needs and the DB-10 was born. They are extremely happy with the outcome.”

The compact mist cannon is mounted on two wheels with a tall handle. A 0.75 horsepower (0.56 kW) fan delivers 3,335 cubic feet per minute (5,666 cu.m/h) of airflow, powered by 120 V current. Mounted on the front of the cannon is a circular manifold with 12 atomising nozzles that fracture pressurised water into a fine mist. The fan forces air through the barrel then pushes millions of tiny droplets in a cone-shaped pattern up to 10 m. Using the 0-50º vertical adjustment, the mist can reach into far expanses or be directed at specific emission zones. It is offered with a standard wheeled carriage but can be specified with alternate mounting as needed.

One driver of the new design is the fact that hoses create droplets up to 100 times larger than atomised mist, far too large to capture airborne particulates. They can use up to 100 gallons per minute (379 litres per minute) of water, causing excessive standing water and runoff, a potential hazard. The DB-10 addresses all these issues.

The DB-10 produces droplet sizes of 50-95 microns in size, roughly the same as the cross-section of a single human hair. This is important because regulators test for respirable dust 10 microns or less. The slipstream created by droplets greater than 200 microns in size can deflect tiny respirable dust particles, rather than absorbing them. That’s why hoses are generally not effective against airborne dust.

Using less than a quarter of the water volume of a handheld 25.4 mm hose, the DB-10 fills the area with a dust-trapping mist that stops particulates from remaining airborne or migrating away from the area, according to the company. The wide area of distribution and gentle settling reduces the chance of pooling and runoff.
