Versatile new mobile dust-suppression unit offers rugged construction and compact dimensions
DUST and odour control-technology specialists BossTek have introduced the newest model in their growing family of self-powered dust-suppression equipment, the DustBoss DB-30 Fusion.
The new design is a versatile and transportable atomized mist unit, engineered with a workhorse electric motor and 30kW generator permanently mounted on a rugged, roadworthy trailer to provide an effective means of delivering powerful dust-suppression technology to sites that lack a convenient power source.
Unlike its larger stablemates, water is supplied to the DB-30 Fusion by a standard 15.8mm garden hose, so it can be used at any location with a working hose bib. Equipped with an in-line 75-mesh, 200-micron filter, the unit can also be specified with special filtration to accommodate the use of non-potable water sources.
With an adjustable throw angle from 0-50° of elevation and a range of approximately 30m (100ft) in calm conditions, the standard configuration includes user-definable 359° oscillation, allowing the unit to cover as much as 31,000 square feet (2,880 square meters) with a powerful dust-trapping mist.
The new design can also be optimized with a variable-frequency drive (VFD) to precisely adjust fan speed. An optional dosing pump is available for precise metering of additives to further enhance particle control.
The extremely water-efficient design consumes just 2.5 gal/min, compared with many competing dust-control methods, such as manual spraying, which can use hundreds of gallons per minute, resulting in over-saturation, run-off concerns and higher water costs.
A touch-screen panel for controlling the DB-30 Fusion is encased in a NEMA 3R cabinet, allowing operators to control oscillation, fan and water. The cabinet is constructed for outdoor use and designed to provide protection against dust, dirt, rain, sleet, snow and ice.
Although the unit carries a three-year/3,000h warranty on the dust suppressor and a two-year/2,000h warranty on the genset, maintenance requirements for the new design are said to be minimal.
If potable water is being used, nozzles typically need to be inspected just once a year. The turntable bearing on the oscillator should be greased annually or as needed for harsh service conditions, and the fan motor should be lubricated every 10,000 hours. Like any diesel engine, the genset should have regular inspections and oil, coolant and filter changes.
‘This design was developed in response to input from the marketplace, which indicated that some customers would benefit from a more compact design that’s well-suited to smaller projects or tight spaces,’ said BossTek’s sales manager, Mike Lewis.
‘The 7.5hp electric motor generates 9,200 cubic feet per minute of airflow, and uses the same industrial-strength construction as the larger models: a manifold with 30 specially-designed nozzles that atomize the water supply, creating droplets between 50 and 200 microns in size for maximum particle attraction.’
BossTek also offer a full line of surfactants, tackifiers, and odour-control additives that are fully compatible with the equipment.
