The CD450 extruded aluminum damper offers Class 1A leakage performance of 3cfm/ft2 @ 1" w.g., which meets the International Energy Conservation Code (IECC) requirements. The airfoil blades provide low pressure drop when fully open and are designed for HVAC systems with velocity and pressures up to 6,000 fpm and 13" w.g.CD450 has a 4” wide frame with finger type jamb seals that provide a “light tight” sealing..

  • Furnish and install, at locations shown on plans, or in accordance with schedules, Low leakage dampers shall meet the following minimum construction standards: Frames shall be 4” x 1” (102 x 25) 6063T6 extruded aluminum channel.
