Model XREB

Model XREB belt drive centrifugal fans are specifically designed for general clean air roof mounted applications. Ideal for use in average length and average resistance duct runs. For a safe, rugged, reliable fan, the XREB is the best choice.

Product Features & Advantages:

  1. Quiet Efficiency – An aluminum, backward-inclined, non-overloading centrifugal wheel is utilized to generate high-efficiency and minimal sound. Wheel cones are carefully matched to the venturi for maximum efficiency. Each wheel is statically and dynamically balanced, for long life and quiet operation.
  2. Meets NEC Codes– NEMA-1 switch is factory mounted and wiring is provided from the motor as standard (other switches are available). All wiring and electrical components comply with the National Electric Codes (NEC) and are either UL/cUL Listed or Recognized.
  3. Easy Wiring Access – A large diameter conduit for installing electrical wiring through the curb cap into the motor compartment.
  4. Precision Tooling – Precisely sized, ground, and polished so the first critical speed is at least 25% over the maximum operating speed. Close tolerances, where the shaft makes contact with bearings, results in longer bearing life.
  5. Long Bearing Life – 100% factory tested and designed specifically for air handling applications with a minimum L(10) life in excess of 100,000 hours [L(50) average life of 500,000 hours].
  6. Easy Access – Constructed of aluminum. Attached with stainless steel fasteners for easy removal and access to the motor compartment and drive assembly.
  7. Static Free Drives – Belts, pulleys and keys are oversized 150% of driven horsepower. Machined cast pulleys are adjustable for final system balancing. Belts are static-free and oil-resistant.
  8. Maximum Motor Life – Cooling fins located on top of fan wheel draw outside air through a large space between the fan shroud and the motor cover directly into the motor compartment. Positive motor cooling with fresh air results in maximum motor life.
  9. Quiet Operation – Vibration isolators support the drive assembly and wheel for long life and quiet operation.
  10. Corrosion Prevention – One-piece, heavy-gauge aluminum with a rolled bead for additional strength directs exhaust air away from the mounting surface. The curb cap and integral deep spun venturi are attached to the windband and constructed of aluminum to prevent corrosion.
  11. Name Plate – Permanent stamped aluminum plate for exact model and serial number identification.
  12. Simple Installation – Aluminum curb cap has prepunched mounting holes to ensure correct attachment to the roof.
  13. Galvanized Birdscreen – Rigid wire protects the fan's discharge from birds and small objects. Standard on all sidewall fans.
  14. Weathertight – Curb cap (with integral deep spun venturi) is constructed of aluminum in one-piece for a weathertight fit.
  15. Weather Resistant – Lower Windband of heavy-gauge aluminum with formed edges for added strength and provides weather resistance.
  16. Motor – Carefully matched to the fan load and mounted out of the airstream (XREB only).
  17. Lifting Points – Select models have various lifting points located on the drive frame or bearing plates.
  18. Seismic Certification – Certified to IBC 2006 and 2009, ASCE 7-05 and California OSHPD certification standards for all seismic design categories. OSHPD/OSP# 0148-10, SDS Value 2.28.
  19. High Wind /Hurricane Zone Certification – Miami-Dade NOA for high wind (150 mph) and hurricane zones. XRED and XREB: 10-0303.04. Florida Product Approval FLPA 13225.1

Model Designation Guide

The Model Designation Guide is designed to completely identify the fan. The correct code letters must be specified to designate belt or direct drive, and roof or wall mounted configurations. The remainder of the model number is determined by the size and performance.
