Duroair Technologies Inc.

- Auto-Adjusting Plant Cleaning System


Duroair has created the world’s first auto-adjusting plant cleaning system that uses state-of-the-art air rotation to provide clean air for your entire shop floor. DuroTower™ features multiple filtering stages that can handle any air contaminant situation with a filter life that extends five times longer than conventional air cleaning systems.

From automotive repair and finishing to metal cutting and welding, industrial processes produce corrosive dust and fumes that can impair employee health and bring production to a grinding halt. DuroTower™ efficiently scoops up these contaminants in an intake downdraft and then floods the entire plant with clean air from the system outlet.

A DuroTower™ air purification solution is:

  • Cost effective via its air revolver system that is ten times more energy efficient than traditional overhead cleaners
  • Flexible with multiple tower models that can be outfitted with casters to function as portable fume extractors
  • Environmentally compliant thanks to the air rotation technology that removes airborne particulates to 1 micron.
  • Cost effective via its air revolver system that is ten times more energy efficient than traditional overhead cleaners
  • Reduces energy costs through the de-stratification of heat layers, homogenizing air from floor to ceiling to within 5 degrees

  • 8,000 – 30,000 CFM design range
  • Small footprint: 40” x 50”
  • Available height options of 11’ or 14’ depending on plant layout
  • Power: Three phase 208-230/460 volt
  • Multiple filter stages for various contaminant situations
  • 10 and 16 gauge welded steel construction
  • Industrial enamel finish
  • Easy two-section installation
  • Can be used with a DuroRoom™ for effective clean room, isolation room, or dust collection applications
