Ruskin Announces New CD450 & CD450V "Light Tight" Control Dampers

We are pleased to announce two new damper models CD450 and CD450V. These extruded aluminum models feature airfoil blades with mechanically fastened blade seals for low pressure drop when open, and achieve Class 1A leakage (3cfm/ft2 @ 1" w.g.) performance when closed. CD450 has a horizontal blade orientation and CD450V is vertical blade orientation. Both models use a 4" wide frame design with finger-style jamb seals for a "light-tight" sealing effect.
