Designed for machining and any other operations which create oil mists, Nordfab Quick-Fit Sealed (QFS) Ducting can significantly reduce risks of leakage from ducting. QFS features laser welded and caulked duct (solid seams eliminate leakage) and double sealing at duct connections.  When clipping the ductwork together, an additional nitrile gasket is placed between the parts to avoid leakage. The Quick-Fit Clip features a generoursly dimensioned sealing gasket held firmly in place by positive over-centre clamping action over the rolled collars at the duct ends to be joined. 

Our standard sizes ranges from 80 mm to 710 mm in diameter and our ductwork is available in galvanised and stainless steel construction.
