Drain Back For Hose to return Oil back to Ducting.
A Drain Back at hose connections prevents oil from leaking from the hose onto machinery and is recommended as an addition in any Nordfab QFS Sealed Duct system. Contact us to order the drain back with alternate options including flanged or other ends, stainless steel or other gauges.
Nordfab offers QFS Sealed Duct to protect against leakage in ducting used in ventilation systems where oil mist is a contaminant. You can also use QFS seals to prevent moisture, such as rain, from entering ductwork when Quick-Fit ducting is being used outdoors. Apply it in any situation where moisture is a concern either internally or externally. All clamp-together ducting has slight leakage. Using QFS increases duct sealing by 10X over our current leakage rate which already meets or exceeds allowable SMACNA leakage rates.
QFS components:
QFS can also be applied after installation. Unlike other clamp-together ducting systems, QFS gaskets are easy to add to an installed system if the need should arise.
