Centrifugal Exhausters
Performance certified is for Installation Type A: Free Inlet, Free Outlet.
Performance ratings do not include the effects of appurtenances (accessories).
The sound ratings shown are loudness values in spherical sones at 1.5 m (5 ft) in a spherical free field calculated per Annex B of AMCA 311.
Values shown are for Installation Type A: Free Inlet spherical sone levels.
Maximum RPM shown obtained with the standard one speed motor, for all other RPM ’s use solid state controller (SSC).
The brake horsepower capability of an exhauster motor is dependent on the degree of cooling the motor receives from the air moving through the motor.
The motor loading beyond the motor nameplate rating does not overheat the motor and is in accordance with the motor manufacturer 's recommendations. It
is therefore not detrimental to the motor and is economically desirable.
