Metal Cutting

Bring Safe, Clean Air to Each Metal Cutting Task

From laser and plasma cutting to grinding and sanding, working with metals can produce a toxic cloud of oil mist, fine particulate dust, and fumes that not only threaten your machinery and electronics, but endanger your most valuable assets – your employees. There’s also the risk of fines if your facility doesn’t walk the compliance talk when it comes to OSHA’s permissible exposure limits (PELs).

 

Modular Air Filtration for Metal Cutting Protection

Duroair combines our DuroRoom™ with DuroTower™ or DuroDust™ technologies into one clean air solution to provide a safe, productive working environment.

We engineer portable, retractable enclosures with recirculating air filtration that can be custom tailored for specific metal cutting processes. By bringing the benefits of clean air to each cutting workspace, Duroair can help you reduce material handling expenses and maximize your facility floor space.

Duroair’s metal cutting clean air solutions provide:

  • Increased flexibility for full use of overhead cranes for moving large workpieces
  • Cost-effective, low-volume workflow efficiency in tandem with larger projects
  • Improved cellular capability for R&D for metal fabrication prototyping and validation
  • Reduced construction and maintenance costs associated with facility-wide HVAC systems and on-going makeup air processes
  • Compliant, clean air per NFPA, OSHA, UL, and EPA requirements, via six-stage, non-vented filtration that captures 100 percent of airborne particulates and eliminates chemicals and vapors
