Upblast Roof Exhaust Fan

Centrifugal Upblast Roof Exhaust Fan

Upblast Roof Exhaust Fans include both direct and belt drive options with efficient backward inclined centrifugal wheels and aerodynamic inlet cone minimizing system effects. Direct drive for short, low resistance duct work with average air volume requirements. Belt drive for average resistance ductwork and high volume requirements. High pressure option for long ductwork with high resistance. Exhaust flows out and upward away from the roof surface. The motors on the fans are out of the airstream. The fans are suitable for applications ranging from storage room to fume hood exhaust and kitchen grease exhaust to smoke control. High performance and durable for general clean air, restaurant grease, smoke control, light contaminants, seismic, high wind, and hurricane applications.

All quotes include fan and roof curb submittals for architectural review and approval. Roof curbs are provided by R&S and will fit any standing seam, R-panel or corrugated metal roof system. Curbs for built-up roofs also available. Curbs to include damper shelves and vibration isolation rails per project specifications. R&S also offers stationary or operable intake louvers for exhaust fan make-up air. Fans, curbs and louvers can include a custom finish to match the building color.
