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.

The world's fastest ducting
For most dust and fume collection requirements and applications, Nordfab Quick-Fit Sealed (QFS) modular clip-together ducting is a crucial component of dust collection, fume extraction, and process ventilation systems. It has the capability to significantly reduce installation time by up to 50%, resulting in cost savings and reduced downtime.

Easy to install
Quick-Fit Sealed is easy and quick to install, designed for effortless cleaning, and can be reused when adjusting facility layouts, providing one of the lowest life-cycle costs of any ducting product. The Quick-Fit rolled edges allow quick and easy connections with the Quick-Fit Sealed Clip when installing, extending, or taking apart runs of duct.
