Model Overview

STXB and STXB-RHUL Upblast Belt Drive Centrifugal Roof/Sidewall Exhaust Fans are designed to exhaust air up to 16,958 CFM in high static pressure applications to 2-3/4". The aluminum exterior provides an attractive appearance. Belt drive results in lower operating RPM and sound levels, making the Series 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 non-ducted applications. Its roof or sidewall mounting options permit location near the area to be ventilated, allowing short duct runs and more efficient operation.

Isolation of motor and drive components from the air stream and, the high-velocity vertical air discharge make the Series 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.

For grease removal applications the fan must be installed per NFPA 96 and with a 40" discharge height and hinged access base.

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