EVAPORATOR FAN PERFORMANCE (cont)
LEGEND
Bhp — Brake Horsepower
ESP — External Static Pressure
NOTES:
1. Units are available with several motor hp options. Refer to the
physical data table.
2. Static pressure losses must be applied to external static pressure
before entering the fan performance table.
3. Interpolation is permitted; extrapolation is not.
4. Fan performance is based on filter, unit casing, and wet coil
losses.
