Nordfab offers the QFS™ Sealed Ducting system to protect against leakage in ducting used in ventilation systems where oil mist and smoke are contaminants. Key components of the Nordfab QFS Ducting system are: 

• Laser welded, solid seam straight duct
• QFS Gaskets on duct ends where joined. We have made improvements to the design of the QFS Gasket so it is easier to install and does not require adhesives. Our new QFS Gaskets are included in our QFS Premium Clip kits. The gasket, combined with the gasket inside our QF Clips, provides dual protection against leakage where ducts are joined.
• Caulked seams / joins on duct components as needed
• QFS Slip Duct Kit where variable lengths needed
• QFS Drain where needed
• QFS Dampers where needed.

Our QFS Sealed Ducting is fast and easy to assemble without the use of special tools.

QFS reduces sources of leakage, decreasing health and safety risks from a contaminated work environment and slippery floors / surfaces.
