Constant Airflow Regulator (Car)MR Modulo and MR Mono Constant Airflow Regulators balance airflows in the ventilation or air conditioning ductworks. They fit easily into a part of the circular ductwork to maintain constant and reliable airflow within a wide range of differential pressure
(50 - 250 Pa) for the standard version and for the high-pressure version (150 - 650 Pa).
Its flexible membrane inflates and deflates according to the difference in pressure between the upstream and downstream flow, thus modifying the airflow. This principle of operation guarantees constant airflow regardless of the pressure variations in the ductwork
The active element of the CAR is a flexible Silicone bulb which inflates and deflates in response to the static pressure difference across the control. The housing is made of Plastic body (M1 fire resistance classification) , for minimum flame spread characteristics. The CAR is made for use in a temperature range of -10 to 60°C .
