Model Overview

The STXD direct drive fans are designed to exhaust air up to 4,780 CFM, with high static pressure capability up to 1-1/2". The non-overloading backward inclined wheel, with its higher static pressure capability, makes this unit suitable for either ducted or non-ducted applications. Its roof or wall mounting permits short duct runs and more efficient 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 air discharge make the STXD ideally suited for the removal of dirty, contaminated and/or high-temperature air from buildings and manufacturing plants. Typical applications include restaurant hoods and similar kitchen exhaust ventilation, fume and smoke removal, laboratory fume hood exhaust and chemical process exhaust.

5-year fan housing warranty, 1-year motor warranty
STXD-RHUL units have 2-year fan housing warranty
