CONSTANT AIR VOLUME - CAV- DAMPER
| HAVA DAMPERLERİ |
Circular Fixed Flow Adjustment Unit is used to control air flow in projects with special requirements such as comfort and hygiene such as operating rooms, clean rooms, special processes, etc.
The desired air flow value can be easily changed on the device with the help of an allen key. It can balance the pressure in the air duct between 20 Pa and 1000 Pa.
All units produced are calibrated in the HVAC calibration laboratory according to the flow values specified in the order. In this laboratory, the calibration is completed by testing one-on-one under field conditions with 7 measurement stations, each with different diameters and nominal flow rates.
Since it is a completely mechanical system, it does not require any power input. Stabilization of air flow is based on meeting the pressure changes in the system. When the pressure in the duct and the air flow rate decrease depending on the pressure, the turning moment acting on the CAV wing decreases and the wing opens. With the opening of the wing, the air flow rate passing through the duct increases and returns to the calibration value.
In the opposite case, when the air flow rate increases, the turning moment acting on the wing increases and the wing closes. With the closing of the wing, the air flow rate passing through the channel decreases and returns to the calibration value.
A mechanism precisely designed with a calibration spring according to the position of the wing ensures that the CAV operates successfully with a 10% deviation rate in the calibrated flow rate.
