HEPA Sweepers

In compliance with OSHA regulations, PowerBoss is committed to maintaining the health and safety of all workers. OSHA indicates that a silica dust exposure control plan includes a number of dust control measures. These measures are customized to meet every organizations needs. With a 99.9% filtration efficiency, PowerBoss holds our safety measures to the highest standard.

When it comes to silica dust control, we’ve got you covered. A large number of our cleaning equipment meets and/or exceeds OSHA’s standards regarding HEPA filtration of carcinogenic dusts. PowerBoss offers three types of dust control methods that can be used to support OSHA’s housekeeping practices including; wet sweeping, water flooding, and dry sweeping. Just to give you an idea of what you should keep an eye out for, browse through tabs below to see a few of those powerful cleaning machines that reach those standards!


What is Crystalline Silica?

Silica, often referred to as quartz, is a very common mineral. It is found in many materials common on construction sites, including soil, sand, concrete, masonry, rock, granite, and landscaping materials.

The dust created by cutting, grinding, drilling or otherwise disturbing these materials can contain crystalline silica particles. These dust particles are very small. You cannot see them. This respirable silica dust causes lung disease and lung cancer. It only takes a very small amount of airborne silica dust to create a health hazard.

Recognizing that very small, respirable silica particles are hazardous, the Occupational Safety and Health Administration (OSHA) regulation 29 CFR 1926.1153 requires construction employers to keep worker exposures at or below a Permissible Exposure Level (PEL) of 50 µg/m3or comply with Table 1 – Specifed Exposure Control Methods When Working With Materials Containing Crystalline Silica of the silica standard.

Dry Sweeping

Our HEPA rider sweepers comply with the OSHA Dust Control Standards. These filtration systems on the sweeper must be 99% efficient to 0.3 micron. .03 micron at 99% efficiency requires a HEPA dust filter to comply. PowerBoss MDC sweepers offer a productive method of sweeping with maximum dust control. Their Atlas and Armadillo 9X Sweepers are yours to choose from!

PowerBoss’ 5 stages of Maximum Dust Control filtration:

  • Stage 1 Vacuumized main broom chamber.
  • Stage 2 Perma Pre-Filter
  • Stage 3 (pleated filter) 95% to 98% efficient from 2.0 –5.0 micron
  • Stage 4 Aggressive filter vibration system
  • Stage 5 (HEPA) 95% to 99% efficient from .30 –1 micron

PowerBoss Atlas Rider Sweeper

The PowerBoss Atlas delivers reliable, cost-effective performance in a maneuverable and compact package. This 64″ industrial sweeper can be used indoors and outdoors in parking lots, universities, hospitals, hotels, resorts, manufacturing facilities, distribution centers and more. Using the latest, most fuel efficient engines on the market, the Atlas comes with your choice of gas/lp or diesel powered option, giving you the versatility to choose the right power source for your application. With only 83 dba noise level, this quiet machine can be utilized with little disturbance to others. By utilizing a premium hydraulic system to raise and lower the main and side brooms, the Atlas’ system is designed to be more cost-effective and reliable over the life of the machine. Adjust the main broom, side broom or dust filter easily. The side broom is also retractable, allowing the operator to swing it away from obstacles, prolonging the life of the brooms and giving you the optional wet sweeping feature for optimal dust control.

Water Flooding

In case the water sweeping method isn’t a viable option for you, the water flooding method may be the way to go. As one of the most effective methods of dust control, water flooding contains the silica dust in a floor scrubber’s water solution and is immediately sucked up through the recovery squeegee and vacuum.

PowerBoss Nautilus Sweeper/Scrubber

The Powerboss Nautilus is a highly maneuverable mid-size ride-on sweeper/scrubber that delivers excellent cleaning results. The large water capacity means prolonged runtime operation, so you can spend more time cleaning then refilling. The Nautilus features one switch operation that turns all the selected functions on and off. Adjust water flow and change brush pressure while the machine is running. This sweeper/scrubber utilizes the water flooding dust control method. It is one of the most effective methods of silica dust control. Based on your cleaning needs, the pressure of the two Eaton hydraulic motors can be adjusted anywhere from 200 to 400 pounds. This gives you the power to remove build-up from floors and bring back the high gloss finish to dirty surfaces. An optional heavy-duty edge scrubber is available that allows the machine to clean close to walls and rack rows. In one pass, the Nautilus deep-cleans and a powerful vacuum quickly dries the surface, leaving floors immediately dry and safe for foot traffic. The PowerBoss Nautilus blows away OSHA’s HEPA regulations!
