The TED50V features Ruskiprene™ blade and jamb seal material. The TED50VXT is designed to protect against extreme cold temperature conditions by using mechanically fastened extruded silicone on the blade seals and ribbed-extruded silicone on the jamb seals.

The damper blade automatically adjusts position to account for changing pressures in the ductwork.

Available in sizes up to 48 inches in width and height, the unit is operated with a hand-held controller from an access point at a diffuser or wall plate. No permanent electrical power is required.

These models of stainless steel backdraft dampers offer three types of frame construction: no flange, flange on discharge, and flange on intake.
