The Broan model 433 automatic shutter is the perfect accessory to Broan gable mount powered attic ventilators, provided you have adequate air intake on the opposite side of the attic or the in the eaves. Attic ventilation is critical to making any home more comfortable while helping to lower energy costs. Stagnant air can be removed, drawing fresh air across the surfaces. The home ventilating institute recommends at least one square foot of open air inlets for each 300 CFM of ventilator capacity.
Features
- Allows more air movement than conventional stationary attic louvers
- Counter-balanced aluminum vanes open automatically when ventilator is turned on, close when fan stops
- Flange fits flush against outside wall for neat, smooth appearance
- Reinforced for strength; provides weather tight closure
- Use with Models 353 and 35316 — sold separately
- For any questions regarding product features, installation, or specifications, please call our Technical Services Dept. at 800-637-1453, Monday-Friday, 8:00 am – 7:00 pm EST.
