PERFORMANCE DATA Continued
AIRFLOW PERFORMANCE CORRECTION FACTORS
The FE4A Airflow Performance table was developed using fan coils with 10-kw electric heaters (2 elements) in the units. For fan coils
with heaters made up of a different number of elements, the external available static at a given CFM from the table may be corrected
by adding or subtracting pressure. Use table for correction.
FACTORY-INSTALLED FILTER STATIC PRESSURE DROP (In. wc)
AIR DELIVERY PERFORMANCE CORRECTION COMPONENT PRESSURE DROP (IN. WC)
AT INDICATED AIRFLOW (DRY TO WET COIL)
NOTE:
Subtract the above pressure drop corrections from unit airflow data when that component or condition is used. The remaining external static pressure
will be available for the duct system.
