Constant Air Volume (CAV) circular damper unit to regulate the air flow to a preset value, operating mechanically, without any external power.
Specifications
The unit adjusts the preset flow rate by its internal spring-operated mechanism, irrespective of the pressure changes in the system. The units are used in both supply and return systems. Since there is no motor, the initial cost is lower, and no operational and maintenance costs. The operating accuracy is within ± 5% band. The required flow rate is adjusted easily using the scale on the body. The units can be used within a pressure range of 50-1000 Pa and 2-10 m/s (advised) air flow speeds. Optionally, a thermal and acoustic insulation, made of glasswool and covered by TS 822 galvanized steel sheet will be cladded around the unit.
