Description

The CCD-GV5-3V-LL is a steel control damper designed and tested to provide an extremely tight seal while remaining cost-effective for the majority of HVAC applications. The standard CCD-GV5-3V-LL is recommended for face velocities up to 2000 fpm and static pressures to 2.5" w.g., while the heavy-duty CCD-GV5-3V-LL-HD option provides rigid, robust damper control for special applications involving high pressure up to 9.0" w.g. The CCD-GV5-3V-LL and CCD-GV5-3V-LL-HD have pressure-sensitive jamb and blade edge selas to provide the ultimate in sealing characteristics without unduly increasing torque requirements. The rigid frame and integrally braced corners provide true damper alignment that greatly resists being installed out of square or out of flat, ensuring on-site performance equal to test results. Factory-installed electric or pneumatic operators are available.
