- NOTES: Shaded boxes represent airflow outside the required 300-450 CFM/ton.
1. Airflow data includes electric heat and filter.
2. Airflow data is with no return grill. When using a return grill on 18 & 24 sizes, decrease numbers above by approx. 10 CFM. For 30 & 36 sizes, decrease numbers above by approx. 50 CFM
- NOTES: Shaded boxes represent airflow outside the required 300-450 CFM/ton.
1. Airflow based upon dry coil at 230V with no electric heat and factory-approved filter. For FMA4X airflow at 208V is approximately the same as 230V because the multi-tap ECM motor is a constant
torque motor. The torque doesn’t drop off at the speeds in which the motor operates.
2. Airflow is equivalent for front or bottom return configurations.
