Dampers

Nordfab Quick-Fit In-line Back Draft Dampers are designed for use in horizontal and vertical lines and are used to reduce backward air flow in the line. If the airflow in your application is upward, please specify that vertical operation is required when ordering. Now available in galvanized, aluminum, stainless and stainless+ with optional no. 4 finish.

Construction:

  • Seam: longitudinal seam is lapped, spot welded, and caulked
  • Collars: located on the exterior side of each port and considered as air flow non-directional. Collars have a laser welded longitudinal seam (exception: 3" collars are lapped, spot welded, and caulked.) If air flow directional product is required, it must be stated on the PO and additional cost may be incurred. A raised lap seam and spot weld are used for attaching the collar to the body and no caulking is used. If caulking is required, additional cost may be incurred
