Performance certified is for installation Type A, free Inlet, free outlet. Speed (RPM) shown is nominal. Performance is based on
actual speed of test. Performance ratings do not include the effects of appurtenances (accessories). The sound ratings shown
are loudness values in hemispherical sones at 1.5 m (5 ft) in a hemispherical free field calculated per AMCA Standard 301. Values
are shown for Installation Type A: free inlet hemispherical sone levels.

The brake horsepower (BHP) capability of a fan motor is dependent on the degree of cooling the motor receives from the
moving airstream over the motor. The motor loading beyond the motor nameplate rating on Acme built fans does not overheat
the motor and is within NEMA recommended limits. It is therefore not detrimental to the motor and is economically desirable.
