Variable-frequency drive said to offer unmatched versatility in dust suppression using atomized mist
IN a move designed to bring greater versatility to their line-up of highly successful dust-suppression equipment, BossTek have introduced an optional variable-frequency drive (VFD) system that allows users to adjust air flow to suit a broader range of applications and working environments.
Driven by customer input from a number of different industries, the new VFD system reduces the need to purchase or rent different models to match the machines’ output to specific project requirements, delivering greater flexibility and reducing the total cost of equipment ownership.
‘Atomized mist technology has been widely accepted as an extremely effective approach to dust management,’ said BossTek sales manager Mike Lewis. ‘This new development will allow users to tailor the fan speed to match the job. It’s useful in a number of different industries, but one good example would be demolition projects,’ he said.
‘Project managers may need the wide coverage and long reach of our larger models on some jobs, but the volume and throw distance may be too much for smaller projects, such as those in crowded urban locations. Instead of using a smaller machine to accommodate their changing needs, now they can simply dial back the air flow to match the requirements of those smaller projects.’
The VFD control will be available via a simple dial or remote control on three of the company’s DustBoss models: the DB-30, DB-45 and DB-60. All three use specialized nozzles and a ducted fan design to atomize the water flow into droplets 50–200 microns in size, which is the optimum for most dust-control applications. Matching the droplets to the most common particle sizes delivers the greatest opportunity for them to collide and fall to the ground.
‘In some applications, a high air flow speed is a distinct advantage, delivering a long throw,’ continued Mr Lewis, ‘but in others, the speed and volume may be a disadvantage. Now users can dial in the speed and throw distance as their requirements change. The variability will range from just a few rev/min up to the maximum delivered by each model.’
