NOTE(S):
a. Refer to fan motor and drive tables for additional data.
b. Fan performance is based on deductions for wet coil, clean 51 mm filters, and unit casing. See table below for factory-supplied filter pressure drop.
c. Maximum allowable fan speed for size 25 units is 20 r/s. Maximum allowable fan speed for size 28 and 30 units is 18.3 r/s.
