--- Shaded boxes represent airflow outside the required 300-450 cfm/ton.
Airflow performance data is based on cooling performance with a coil and no filter in place. Select performance table for appropriate unit size
external static applied to unit allows operation within the minimum and maximum limits shown in table below for both cooling and electric heat
operation.
Blower Data
NOTES: Airflow based upon cooling coil at 230V with no electric heat and no filter. Airflow at 208V is approximately the same as 230V
because the mult-tap ECM motor is a constant torque motor. The torque doesn’t drop off at the speeds in which the motor operates.
