NOTES:
1. Airflow based on dry coil at 230V with factory approved filter and 2 element electric heater.
2. Not recommended for use above 0.60 inches water column external static pressure.
3. Shaded cells indicate airflow is greater than 450 CFM per ton.
STATIC PRESSURE CORRECTION FROM DRY TO WET COIL (inches of water column)
AIRFLOW PERFORMANCE chart was developed using fan coils with DRY coils.
When taking a static reading across a WET coil, adjust the static pressure numbers in the AIRFLOW
PERFORMANCE chart by adding the values in this table.

STATIC PRESSURE CORRECTION FOR ELECTRIC HEATERS (inches of water column)
AIRFLOW PERFORMANCE chart was developed using fan coils with 2--element electric heaters (7.5 kW or 11 kW).
When using a 1--element electric heater (5 kW), or no electric heater, adjust the static pressure numbers in the
AIRFLOW PERFORMANCE chart by subtracting the values in this table.
