BossTek has introduced the DustBoss DB-10 atomized mist cannon, which can be used to suppress indoor particulate emissions during demolition and raw material handling. Engineered for enclosed working environments, the maneuverable unit provides suppression in a compact, portable design. The outcome is airborne particle control with minimized emissions and less standing water.
“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,” said Mike Lewis, dust control specialist at BossTek. “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.”
Operation
The compact mist cannon is mounted on two wheels with a tall handle. A ¾-hp fan delivers 3,335 CFM of airflow, powered by 120-volt current. Mounted on the front of the cannon is a circular manifold with 12 atomizing nozzles that fracture pressurized water into a fine mist. About as loud as a hand-held hair dryer, the fan forces air through the barrel then pushes millions of tiny droplets in a cone-shaped pattern up to 30-ft. (10 meters). Using the 0-50º vertical adjustment, the mist can reach into the rafters of warehouses or be directed at specific emission zones. It is offered with a standard wheeled carriage but can be specified with alternate mounting as needed.
Applications
Beyond space constraints, the DB-10 solves several issues associated with dusty indoor operations. During indoor demolition, for example, harmful dust can fill the area and drift across the site line, creating a violation, but atomized droplets help control dust at the point of emission.
“The dust emissions from indoor demolition or concrete cutting and breaking can create tiny particles that you can’t see,” Lewis pointed out. “These can get deep into your lungs and cause serious breathing issues, but the mist droplets are small enough to capture individual particles at the moment of emission and drag them to the ground.”
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, like those found in indoor demolition. The slipstream created by droplets greater than 200 microns in size can deflect tiny respirable dust particles, rather than absorbing them. Using less than ¼ of the water volume of a handheld 1-in. (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. The wide area of distribution and settling reduces the chance of pooling and runoff.
