CD504 Alum. rectangular, airfoil, class I leakage, heavy duty, 6000 FPM, 13" w.c. max.
The CD504 Thinline Control Damper offers the lowest leakage attainable with a commercially built thinline blade damper. It also features:
- Concealed linkage for low maintenance and low air turbulance.
- Airfoil blades, which have greater strength, produce less sound, greater sealing ability, and static pressure loss.
- Extruded aluminum construction.
