24 In. 2-Speed Belt Drive Whole House Fan with Shutter

Quick Overview

Model CX24BDM-2SPD

Whole House Fans are ideal for residential use in mild to moderate climates as a supplement to air conditioning. Our belt drive units have been engineered to offer a superior performance with a more stable motor mount that is stronger than typical tube-style bracing and virtually eliminates vibration alongside an automatic shutter in a powder-coated white finish to blend in seamlessly with your ceiling. Install as a joist-in or joist-out configuration. Whole House Fans offer an efficient way to reduce cooling costs by pulling fresh air in from the outside, expelling the warm air up into the attic, and pushing it out through the attic exhaust vents.

  • Designed for houses with 1,200 - 1,800 sq. ft. attics
  • Steel construction and dual ball bearing technology with automatic shutter
  • Joist-in or joist-out installation. For ceiling install only - not for wall exhaust use.

  • Requires 8 - 10 sq. ft. (1,152 - 1,440 sq. in.) of NFA
  • C/UL/US Listed

24 Inch Belt Drive Whole House Fan with Shutter is rated 1.0 out of 5 by 2.
Rated 1 out of 5 by from Motor/bearings broke in a month I installed the fan in May (before the summer heat) and in June, the motor was making a noise that sounded like the bearings had failed and was barely running strong enough to open the shutters (which don't always close but thats another issue). I have to pay out of pocket to ship the motor back to Texas and wait for them to send me one back and then re-install the motor in in the summer heat in my attic. Not very happy.
