Product Overview

  • Aluminum and steel construction for durability
  • Provides a weather tight seal
  • Boasts an easy-to-install design
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.

  • 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

Questions & Answers

Is there a wildlife grille or can one be added?

Is there a wildlife grille or can one be added?
Asked by: TH
This fan does not come with one. You can probably add one from the inside or perhaps box one in from the outside but it will reduce the efficiency of your fan

Do the louvers operate independently or are they joined with some kind of metal wire device?

Do the louvers operate independently or are they joined with some kind of metal wire device? I'd be using these in an unconventional way, on a porch, is why I ask. I'd love it if the louvers were rigged to all work together so I could manually open and close the vents.
Asked by: Studiopop
I think the force of the air generated by the fan blows and holds them open while its on. Then gravity shuts them when it stops.The bottom of the flaps are weighted so they go back to the closed position when no air is blowing on them.
