Equipped with a 10-hp booster pump to increase water pressure as much as 150 psi from a 2-inch supply hose, the DB-60 has an adjustable elevation angle from 0-50 degrees. The unit can also be outfitted with a dosing pump to accommodate odor control additives or surfactants to further enhance binding of dust particles.
The DB-60 uses a straightforward, direct-drive fan motor. It has no drive belts, diesel engines, or complex gear systems that could present dependability problems in the difficult service environment of a demolition site. Despite its size, the machine requires minimal maintenance. Lubrication of fan motor bearings is recommended every 10,000 hours, while the oscillation motor is lubricated for life.
In CalTrans worksites, dust control is no longer a luxury but a contractually mandated component of demolition, construction, and certain types of maintenance work, subject to inspection. “Particularly in the city and greater San Francisco Bay area, dust suppression strategies and techniques are constantly being reviewed and refined,” Yan says. “There’s been increasing focus and scrutiny on developing multipronged approaches to site maintenance, including dust management and water pollution prevention.”
With the increase in materials recycling onsite, and trends toward tighter regulation of jobsite effluent of all kinds, industry professionals are more motivated than ever to find efficient, cost-effective methods of dust suppression.
With the significant reduction in airborne dust, Yan and his crews contributed to a healthier workplace on the complex Doyle Drive demolition project, while protecting the surrounding communities and natural environment.
“I was particularly impressed by the range of the unit, and the relatively low noise level during operation,” he says. “The ability to easily mobilize and relocate the units as needed was also a big advantage.” Also, effective suppression minimized the opportunity for abrasive dust to enter air intakes on heavy equipment, extending air filter life and reducing the potential for unnecessary wear.
“This was a very high-profile job,” Yan adds. “Our goal was to take all practical measures, using the best technology available, to mitigate the demolition dust and safeguard people, property, and the environment.”
