The brake horsepower capability of a fan motor is dependent on the degree of cooling the motor receives from the moving air stream over the motor. The motor loading beyond the motor name plate 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.
Performance certified is for Installation Type A: Free inlet, Free Outlet Power Rating (BHP) does not include transmission losses. Performance ratings do not include the effects of appurtenances (accessories).
The sound ratings shown for Models EC and ECH are loudness values in hemispherical sones at 1.5 m (5 ft) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type A: Free Inlet hemispherical sone levels.
The sound ratings shown for Models EC-S and ECH-S are loudness values in fan sones at 1.5 m (5 ft) in a hemispherical free field calculated per AMCA Standard 301. Values shown are for Installation Type A: Free Outlet hemispherical sone levels.
