Quick-Fit Sealed (QFS) Ducting
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. All bends, branches, reducers, and other products with joints or collars are epoxy caulked. When clipping the ductwork together, an additional nitrile gasket is placed between the parts to avoid leakage. The Quick-Fit Clip features a generously dimensioned sealing gasket held firmly in place by positive over-centre clamping action over the rolled collars at the duct ends to be joined. For added security, a locking pin may be inserted.
