Designed for machining and any other operations which create oil mists, Nordfab QFS Ducting can significantly reduces risks of leakage from ducting. QFS features laser welded and caulked duct (solid seams eliminate leakage) and double sealing at ductwork connections. Ductwork is available in galvanized and stainless steel construction. See our QF section for additional products which are available with sealing options.
