Industrial Air Purification With Bottom-Line Benefits

As the world’s first indoor air filtration system, the DuroPure™ patented, six-stage filtration system captures 100 percent of airborne particulates, including hexavalent chromium, and thoroughly cleans the air of VOC gases, safely returning clean air back to the working environment. Air is so clean that third-party testing confirmed it falls well below OSHA allowable standards. DuroPure™ technology also eliminates the need to exhaust contaminants to the outside environment.

The advantages of clean air go beyond environmental and OSHA compliance. A DuroPure™ system offers capital cost savings by eliminating upfront installation costs for venting and air make-up. Annual operating costs are also reduced through energy savings in addition to eliminating or reducing permitting costs.

DuroPure™ Non-Vented Air Purification

DuroPure’s™ recirculating airflow technology delivers more than capital cost savings; it speeds coating and painting dry times and its six-stage filtration removes airborne contaminants that can compromise surface prep and finishing processes.

A DuroPure™ solution:

  • Safely captures 100 percent of airborne particulates, including hexavalent chromium, and eliminates VOCs so air recirculates back into an indoor working environment
  • Is flexible for isolating your large-scale work pieces and preventing material handling bottlenecks, when paired with our retractable DuroRoom™ enclosure
  • Is portable for moving when and where you need it to control contaminants from your blasting, grinding, spraying, and welding processes
  • Can easily be integrated into a cellular manufacturing environment
  • Is able to reduce security risks by avoiding building penetrations
  • Is cost-effective for reducing energy waste and eliminating air make-up expenses associated with facility-wide HVAC systems
