Info & Guides

Description

Trapped heat and moisture make kitchens, warehouses and barns uncomfortable places to work. The Hessaire 20 Inch Shutter Mounted Exhaust Fan pulls that stale air through the wall and sends it outside, and its build works in both residential and commercial settings. Odors go out with the air, so the fan that cools your space also keeps it smelling fresher.

Safety and stability got the same attention. The rounded wire guard meets OSHA spacing requirements. Its curved shape also stiffens the whole assembly, which cuts down on vibration when the fan runs for long shifts.

Key Features and Benefits of the Hessaire 20 Inch Shutter Mounted Exhaust Fan

  • High Airflow: The 3-speed fan moves up to 2,860 CFM to ventilate areas up to 775 square feet, while the variable speed fan generates 3,340 CFM for spaces up to 900 square feet.
  • TEAO Motor: The Totally Enclosed Air Over motor is sealed against moisture and dust, so it keeps running for years with little maintenance.
  • Galvanized Steel Housing: The frame and blades are made of corrosion-resistant galvanized steel, for long-term durability.
  • Gravity Shutters: Heavy-duty aluminum shutters with reinforced corners open fully when the fan runs. When it stops, they close against weather-stripped louvers for a tight seal.
  • Thermal Overload Protection: A built-in overheat sensor shuts the motor off automatically if it gets too hot, which protects the fan and your space.
  • Modest Power Draw: The fan uses at most 322 watts and 2.8 amps on 110-120 volt power, so it moves a lot of air without drawing much power.
  • Plug-In Setup: It arrives fully assembled and pre-wired with a 9-foot grounded 115-volt cord, so you can start it as soon as it's mounted.
  • Rough-In Opening: It needs a wall opening of 20.5 x 20.5-Inches (L x W).
  • Overall Dimensions: The 3-speed model is 13"D x 23"L x 23"W, while the variable speed model measures 16"D x 23"L x 23" W.
  • Sound Level: It's rated at maximum 7 sones, which suits busy work areas where some fan noise is expected.
  • UL Certified: UL certification means the fan's electrical safety has been checked by an independent testing organization.

Multiple Speed Options

You can get this shutter exhaust fan as a 3-speed or a variable-speed model to match your needs.

  • 3-Speed Model 20SF4T90C: This model has 3 fixed settings for quick air speed changes.
  • Variable Speed Model 20SF4V180C: This model lets you set airflow anywhere across its range to match the need or the time of day.

Note: For variable-speed operation, a variable speed controller is required and must be installed by a certified electrician.

Sylvane's Expert Take

For a restaurant, warehouse, workshop, barn or greenhouse where effective ventilation is needed, the 20-inch Hessaire Shutter Fan is a perfect choice.  Choose the 3-Speed model for 3 quick speed settings. If you need finer control, the Variable Speed model might be a better fit. 

The sealed motor and steel housing are what you'll value most over time, since moisture and dust have little effect on them. For hot, humid rooms close to 900 square feet, this fan earns its spot in the wall.

    I may buy a second unit. We are living without air condition

    I use this fan in an attic window of a two story house to exhaust summer hot air and circulate cool evening air through the house all night. I have the 1/4 hp variable speed model, but used only as a single speed, without the speed control. I built a plywood shroud for it so as to use it as a window unit. It works very well: powerful, but noisy. The noise level is no fault of the fan, it is just what it takes to move that much air. Actually, this fan is as smooth and vibration-free as one could expect. It is a robust, on/off, one way, simple fan and I love it for my application. Nothing rinky-dink, landfill-bound about it.

    Nice Exhaust Fan

    The fan arrived in perfect condition and on time. Installing the fan is pretty straight forward. I installed mine on a Cleary building. I put mine on a switch so I don't have to plug/unplug all the time. The louvers will fluctuate in the wind a bit when not in use, so I installed a hinged box made of OSB board to cover the fan from the inside. This helps keep the warm air in from my furnace. Fan is working well. This my second order with Sylvane. They're a good company to buy from. I like that they accept PayPal too. I'll be purchasing an air conditioner next.

    I would definitely recommend this to someone.

    This fan was every thing I expected. I have used it for a few weeks and it is performing well. I am ordering another one for another building. Thanks for a fine product
