The RACAV constant airflow regulator is dedicated for ventilations systems to keep the constant air flow. The device operates without power supply, from minimum differential pressure range referred to in diagram 1 to maximum differential pressure range equal to 1000Pa.
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.
