Product Details

galvanized steel square constant flow high quality used damper

Product Description

Constant air damper, a kind of mechanical self-powered device, is suitable for HVAC ventilation system where

constant air volume is needed. It depends on the air flow power to control the damper without any other external

power, which can ensure a preset constant air volume in the whole system.
