DIRECT DRIVE & BELT DRIVE CENTRIFUGAL ROOF EXHAUSTERS
MODEL STXD DIRECT DRIVE CENTRIFUGAL ROOF EXHAUSTER
MODEL OVERVIEW
Model STXD direct drive fans are designed to exhaust air up to 4,780 CFM in high static pressure
applications to 1-1/2”. The aluminum exterior provides an attractive appearance. The non-overloading
backward inclined wheel with its higher static pressure capability
makes this unit suitable for either ducted or nonducted applications.
Its roof or wall mounting permits location near the area to be
ventilated, allowing short duct runs and more efcient operation.
Direct drive units use smaller diameter wheels with lower rpm's,
resulting in low sound levels and quiet operation. They have
no belts or fan bearings to maintain or adjust and consequently
require very little maintenance.
Isolation of the motor from the air stream and the high velocity vertical (roof) or horizontal (wall) air
discharge make the Model STXD 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.
