BossTek is offering an optional Variable Frequency Drive (VFD) system that allows users of its dust suppression equipment to adjust air flow for greater versatility.
The company said the move means that the equipment is suitable for a broader range of applications and working environments. Driven by customer input from a number of different industries, the new VFD system is intended to reduce the need to purchase or rent different models to match the machines’ output to specific project requirements, meaning greater flexibility and lower total cost of equipment ownership.
“Atomised mist technology has been widely accepted as an extremely effective approach to dust management,” said Mike Lewis, BossTek sales manager. “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.
“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 downtown 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.”
Lewis added that the VFD is likely to be attractive to companies with variable needs, including concrete curing, cannabis and hemp operations, transfer stations, slag handling and indoor applications.
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 specialised nozzles and a ducted fan design to atomise the water flow into droplets 50-200 microns in size, which is claimed to be 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,” said 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 RPMs up to the maximum delivered by each model.”
Another example would be concrete curing, where atomised mist has proven successful in controlling humidity for maximum strength of the finished product. On airport runways and other large projects, the 60m throw distance may be desirable, but on smaller pours, contractors may want to dial it back to a fraction of that. With the VFD, they can easily do so, without having to use smaller models.
