Belt Drive Centrifugal Roof Exhauster
Model PL
Model PL belt drive fans are downblast centrifugal power roof
ventilators designed for exhausting clean air. Capacities up to
31,810 CFM and up to 1 inch static pressure. The PL is built to
be a low profile exhauster. PL exhausters are suitable for all
types of commercial and institutional buildings such as schools,
hospitals, office buildings and retail stores.

Performance certified is for installation type A: Free inlet, Free Outlet. Performance ratings do not include the effects of appurtenance (accessories). The
sound ratings shown are loudness values in hemispherical sones at 1.5 m (5ft) in a hemispherical free field calculated per AMCA Standard 301. Values
shown are for Installation Type A: Free Inlet hemispherical sone levels. 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.
Power rating (BHP) does not include transmission losses.
