Constant Air Volume Regulator
Constant Air Volume Regulator
Standard Model: CAV-SR
The Constant air volume regulator is an air-engineering device that maintains constant volume of air flow within fluctuating pressure range without any external energy source. The controller starts its operation according to its nominal size and the regulated amount of air when the minimum pressure difference between the front and rear part of the controller reaches 35 to 55 pa.
Product Description
The Constant air volume regulator is an air-engineering device that maintains constant volume of air flow within fluctuating pressure range without any external energy source. The controller starts its operation according to its nominal size and the regulated amount of air when the minimum pressure difference between the front and rear part of the controller reaches 35 to 55 pa. The control of larger air volumes requires a higher difference in pressure. Using the constant air flow controller, HVAC designers have a choice at their conveyance that needs no energy supply while providing for the different factors designed.
COSMOS Constant Air Volume Regulator is designed for ventilations systems to keep the constant air flow. The device operates without power supply, from minimum differential pressure range to maximum differential pressure range. Beyond that range the accuracy of the maintained air flow may deteriorate. The regulator can be used in intake and exhaust installations, as well as in comfort and industrial ventilations.
Constant Air Volume Regulator helps to obtain a constant flow within a pressure range from 50 to 200 Pascal. It is used in ventilation of air conditioning systems to supply to return air. The air is forced to pass through predetermined space in which a damper can change the position according to the specified air flow. The damper is attached on to a calibrated spring and therefore no auxiliary power is needed
Features
● Specially designed variable force spring mechanism for automatic air flow control.
● Wide range of air volume adjustment as per size.
● Low leakage as connection with rubber seal.
● Easy Installation & Maintenance Free
Options
Constant air flow regulators with insulated casing.
Operating Principle
Constant Air Volume Regulator enable regulation of individually required amounts of air in separate ventilation system branches.
Accuracy of constant air flow volume is in average + 10 – 15 % of set value.
Adjusting of required constant amount is done by the user by adjustment on the right side of the cover and by moving the indicator cursor opposite to the sign on the scale.
Rubber sealing at the end of CAV are used for tight connection with the duct.
Inside is the regulator setting of constant outgoing amount of air provided by charging the blade angle which is changed as a consequence of effect of supplied air to the blade linked through the arm with specially design spring and adjustment mechanism.
The regulator ensures system balancing by maintaining constant air volume and are very common in buildings like offices and hotels.
