Exhaust Fans
Several different types of Exhaust Fans are utilized in commercial kitchen applications: Centrifugal Upblast and Sidewall Exhaust
Fans, Utility Fans, and Inline Fans.
Centrifugal Upblast and Sidewall Exhaust Fans - Series C
The Centrifugal Roof Upblast and Sidewall Exhaust Fans include both direct and belt
driven fans with backward inclined centrifugal wheels. These spun aluminum fans are
specifically designed for roof mounted or wall mounted applications. Contaminated or
grease laden exhaust air can be discharged directly upward, away from the roof surface or
discharged out and away from building walls. The fans are suitable for applications such
as range hood or fume hood exhaust. The model CUBE is available in 3 pressure ratings:
standard, HP (high pressure) and XP (extended pressure). A steel version, USGF, is also
available. Capacities range from 80 to 26,000 cfm and up to 5.0 in. wg. UL-762.

Utility Fans - Model SWB
The Utility Fan is belt driven and features a backward inclined centrifugal wheel. This fan is
suitable for ducted exhaust, supply, and return-air applications. Typical applications include
commercial kitchens and fume hoods. Capacities range from 500 to 23,000 cfm and up to
4.0 in. wg. UL-762.

Models KSFB and KSFD
Models KSFB and KSFD economically supply untempered make-up air where needed.
Kitchen make-up air applications are common and an extended weatherhood option
provides a 10 foot separation between intake and exhaust fan discharge. Airflow volumes
range from 800 to 10,500 cfm

Inline Fan, Backward Inclined Wheel - Model TCB
The TCB uses a backward inclined centrifugal wheel for high efficiencies and low sound
levels when used in medium pressure ducted systems. All TCB inline fans are belt driven
with the motor out of the airstream. Optional construction includes the roof upblast model
TCBRU and roof supply model TCBRS. AMCA licensed for Sound and Air Performance.
