Constant air regulator CAR-S is mechanical regulator used to maintain a constant volume flow rate independently of the pressure variations in ventilation and air conditioning systems.
Description:
Constant air regulators CAR-S is mechanical regulators used to maintain a constant volume flow rate independently of the pressure variations in ventilation and air conditioning systems.
Regulators can be installed in a supply and extract air systems. Each regulator is set to the required flow rate and subjected to the aerodynamic function test conducted in our test facility.
The flow rate can be easily set or reset by adjusting the control lever on the calibrated scale. This is done by loosening the control lever’s wing bolt and turning the control lever’s arrow pointer to the desired value. When adjusted, the control lever is fixed by tightening the wing bolt.
Regulators work at the differential pressure range from 50 to 1000 Pa and the air velocity range from 3 to 10 m/s. As a reference value, recommended air velocity is around 6.5 m/s, where the accuracy of a constant flow rate is usually within a tolerance from ±5 % of the set value.
The regulator can operate, without the direct influence of weather conditions on the operation, within a temperature range of -20°C up to 80°C and relative humidity up to 80%. Regulators should be stored in closed and dry places at temperatures from -20°C to +60°C.
The damper blades shaft is supported by two smooth running maintenance free brass bearings. Pneumatic shock absorbers smooth out the damping shock impulse, preventing the vibration and oscillation of the damper blade to ensure sensitive responding behaviour and a precise control.
