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.

We are pleased to announce our new GenSet damper models designed to provide maximum combustion air and pressure relief quickly for emergency generator start up. These models are specially equipped with our new fast acting 8-second spring return electric actuator in a NEMA 4X weather enclosure, and have independent section operation to ensure optimal performance. In addition, all three models meet Class 1A leakage (3 cfm/ft2 @ 1" w.g.) when closed.
