- Airflow outside 450 cfm/ton.
NOTES:
1. Airflow based upon dry coil at 230v with factory−approved filter and electric heater (2 element heater sizes 1800 through 3600, 3 element
heater sizes 4200 through 4800). For FEM4P models, airflow at 208 volts is approximately the same as 230 volts because the ECM motor
is a constant torque motor. The torque doesn’t drop off at the speeds the motor operates.
2. To avoid potential for condensate blowing out of drain pan prior to making drain trap:
Return static pressure must be less than 0.40 in. wc.
Horizontal applications of 4200 − 4800 sizes must have supply static greater than 0.20 in. wc.
3. Airflow above 400 cfm/ton on 4800−4800 size could result in condensate blowing off coil or splashing out of drain pan.

STATIC PRESSURE CORRECTION FOR ELECTRIC HEATERS (inches of water column)
Airflow performance chart was developed using fan coils with 10 kW electric heater (2 elements) in the 1800 − 3600 model
sizes, and 15 kW electric heaters (3 elements) in the 4200 − 4800 model sizes.
When using a different number of heater elements, adjust the static pressure numbers by adding or subtracting the values in
this table (for a given CFM, more electric heater elements create higher static pressure drop).
