1. AIRFLOW SETTING

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.

Performance charts found in the specifications sheet reflect this data, with the available range (shaded)

and marked setpoints (lines). The CAR3 will maintain the airflow accurately to within +/- 10% of the

indicated lines below for each marked setpoint. At the higher airflow rates, the minimum pressure

required to achieve the selected airflow may exceed 0.12 in. w.g.

Each diameter has a unique range for both low- and high-pressure variants. The CAR3-L (low-pressure)

is designed for systems with pressures between 0.12 and 1.2 in. w.g. (30 to 300 Pa), and CAR3-H (high-

pressure) between 0.4 and 2.8 in. w.g. (100 to 700 Pa). Factory calibration of the CAR3 is available on

request. Blue color dial = Low-Pressure / Green color dial = High-Pressure.
