CAR3 Aldes Constant Airflow Regulator, Low Pressure

The Aldes CAR3 Constant Airflow Regulator is a pressure independent balancing damper that automatically regulates airflow in duct systems to constant levels. The CAR3 requires no electric or pneumatic power or sensors, and works solely off system pressure.

Airflow rate can be set or adjusted by rotating the dial from either side. The airflow indicator will move to show the selected CFM. The airflow label has multiple defined setpoints, but the unique adjustment mechanism of the CAR3 allows for infinite adjustability between the minimum and maximum limits.
