Series Description
The Ruskin CDRS25 Series round damper frames are made of 20-gauge welded, galvanized steel, 7 in length. Blades are double-skin galvanized steel, strength-equivalent to 14-gauge steel but lighter to handle. Shaft extensions are 1/2 in diameter with stainless-steel bearings for long-life damper actuation. Standard neoprene blade edge seals offer superior low-leakage performance. Optional aluminum or stainless-steel construction is available, as well as an actuator mounting bracket.
