The BlowBeast. Rotobrush’s New Portable Negative Air Machine

News Negative Air Machine


GRAPEVINE, Texas—Rotobrush® International LLC, a global market leader in providing indoor air quality solutions, is announcing the latest addition to its product lineup. The BlowBeast Negative Air Machine is a portable air duct cleaning solution that is taking negative air portability to a new level.

“We know contractors are searching for equipment that makes it easier for them to perform air duct cleaning,” says Bob Elledge, President and CEO of Rotobrush International. “The BlowBeast is easy to maneuver without losing the power needed to effectively remove airborne dust and pollutants from any air duct system.”

For more than 25 years, Rotobrush has been an industry leader in providing portability with many of their brush and vacuum machines. Most negative air systems are bulky, big and take up a lot of truck space, which was the reason Rotobrush wanted a solution for portability in the negative air industry as well.

Negative air machines are ideal for situations where a traditional brush and vacuum won’t be as effective. The BlowBeast provides superior air flow and high vacuum capabilities to remove contaminants and improve indoor air quality. With a removable pod for collecting the contaminants, contractors will also have an easier time getting their machine ready for the next job site.

Features of the BlowBeast:

  • Compact and portable design.
  • Innovative removable pod.
  • Heavy-duty, durable carrier.
