DuroTower™ Auto-Adjusting Plant Cleaning System
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
