## Description

The power shutter exhaust fan is perfect for removing excess heat, moisture, and unpleasant odors from virtually any commercial location, including restaurants, factories, warehouses, barns, and greenhouses. This fan features aluminium blades, automatic shutters that open and close in tandem with the operation of the fan. The completely enclosed motor is thermally protected and permanently lubricated. The fan comes fully assembled out of the box; only installation required is the electrical hardwire.

Review: This is a great static vent. I used it for intake for my greenhouse. - This static vent work great. The three louvers are light weight and open accordingly as you turn on an exhaust fan. I shielded the vent with a protective cover to keep blowing rain out. Installation is easy. I did add a small strip of weatherstripping to aid in the seal to the structure. It is a little pricy but overall, a great value.
Review: Sturdy and nicely packaged. - I saw few negative comments about this product. Honestly this is well made product and shipped carefully packaged. I believe that the blue color is to prevent annoying reflections and to protect aluminum from corrosion damage. I like this product and recommend it.

### ⭐⭐⭐⭐⭐ Works fine
*by C***N on March 21, 2026*

Works well. Installs easy. Comes with things I'm guessing you'll need. I used it on corrugated poly-carbonate sheets for a green house. Haven't noticed any squeaks or clanking. Appears to be made out of a thin metal, not plastic at all. The one annoying thing is the blue protective sticky plastic they left on it is impossible to get off completely on the top louver because it wraps around to the back that is inaccessible.
