QF Machine Adapter

QF Machine Adapters allow easy connection of QF ductwork to machines requiring dust or fume removal. Ends are QF (rolled edge) to NOFIT (plain edge). Longitudinal seam is solid laser welded. QF Machine Adapters come in galvanized or 304SS metal. Adapters over 24 inches come in Flanged only along with 14 gauge galvanized metal which is on the XD product line.

Quick Fit Machine Adapters allow easy connection of Quick-Fit (QF) ductwork to machines requiring dust or fume removal. Ends are QF (rolled edge) to NOFIT (plain edge). Longitudinal seam is solid laser welded for strength and to reduce leakage.

QF Machine Adapters are manufactured as follows:

  • They are manufactured in galvanized or stainless-steel metal up to 24 inches with a standard 20 to 22 gauge and an optional 18 or 16 gauge

Heavier gauged galvanized metal with sizes up to 40 inches are available in the XD line.

  • Construction: Longitudinal seam is laser welded.
  • Standard QF ends can be changed to Raw with a defined ID dimension (RawID), Raw with a defined OD dimension (RawOD), No Fitting or just a raw end (NoFit), Flexible hose adapter (RawFlex), Flat Flange (FFL), Angle Flange (ANGFL), or Van Stone (VanStone).

NOTES:
  1. At temperatures ranging between 390° F and 480° F, the zinc-iron alloy layers in the galvanized steel will continue to provide a high level of protection from corrosion. However, there may be some peeling, changes in mechanical properties, and reduction in the corrosion protection. Recommended maximum service temperature is 390° F.
  2. For 304 SS metal, bluing may occur at temperatures of 800° F and above.
  3. Rock River Silicone Sealant and Red Devil HVAC/R High Temperature Silicone Sealant are not able to be painted.
