MODEL OVERVIEW
Model STXB belt drive fans are designed to exhaust air up to 3,975 CFM in high static pressure
applications to 1-1/2”. The aluminum exterior provides an attractive appearance. Belt drive results
in lower operating RPM and sound levels, making the Model
STXB well suited to applications where quiet operation is
important. Belt drive also permits easy performance adjustments
when needed to balance the total ventilation system. The
non-overloading backward inclined wheel with its higher static
pressure capability makes this unit suitable for either ducted or
nonducted applications. It’s roof or sidewall mounting options
permit location near the area to be ventilated, allowing short duct
runs and more efcient operation.
Isolation of motor and drive components from the airstream and the high velocity vertical air discharge
make the Model STXB ideally suited for the removal of dirty contaminated and/or high temperature
air from processes and buildings. Typical applications include restaurant hoods and similar kitchen
exhaust ventilation, fume and smoke removal, laboratory fume hood exhaust and chemical process
exhaust. The STXB line of fans is available in a variety of construction options, see the chart above for
the STXB that is right for your application.
