NOTES:
1. Airflow based on dry coil at 230V with factory approved filter and electric heater
(2 element heater for model sizes 1800 -- 3600, 3 element heater for model sizes 4200 -- 6000)
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 above was developed using fan coils with DRY coils.
When taking a static reading across a WET coil, adjust the static pressure numbers above by adding the values in
this table (for a given CFM, wet coil will have greater static pressure drop than dry coil).
