iLIVING ILG8SF24V-T 24 inch Shutter Exhaust Attic Garage Grow, Ventilation Fan with 2 Speed Thermostat 6 Foot Long 3 Plugs Cord, 24" - Variable, Silver

Works well in 20’ x 50’ x 20’ tall enclosed barn. The variable speed and thermostat control features work good.You’ll need intake air source if structure is fully enclosed.

This fan works better than I could have ever dreamed. It took all of the heat out of our attic within about 3 minutes of turning it on. I put on an IOT and it hooked to our wifi and I can turn it on and off using the app. Very happy with the performance of this fan. It moves a lot of air very fast.

It was installed in a 45’ metal storage Trailor ie(Actually a new unused shipping container), which gets very hot in summer months when closed up, so this removes the hot air and brings in fresh outside air to ventilate this unit.Thermostatically controlled makes the operationVery simple, plus it can be over ridden to Manual with 3 speed switch control.The large aluminum vents opens when on and closes automatically when off.Worked flawlessly , Very Happy with my purchase.

Absolutely great temperature control for my greenhouse. I have a personal greenhouse I built last year to provide veggies for my family and really struggled with high temps especially in the hotter summer months. This fan is incredibly effective for a 150 sq. ft. greenhouse. Looking forward to seeing it's performance during the hotter days to come. Definitely consider your intake venting as this fan creates impressive negative pressure in a sealed environment. Also, take some time to adjust and understand the built in thermostat to obtain accurate temperature control. All in all, a great purchase.

Installed in the top end wall of my greenhouse. Louvers work to keep out bugs. Love the 2 speed fan option. Had a light switch installed so I don't have to drag a ladder around to turn it on. Quiet motor. The only noise is one louver rattles on the connecting bar when in operation.

I replaced a 16 inch fan with this, and I am very glad I did. At medium speed, it moves a lot of hot air in my greenhouse.I ordered the fan with a thermostat, but, like other reviews, I ended up using a separate temp control as the internal unit got a bit weird and I would find it running when the heat was on.( The problem was more due to the thermostat being so high up that the hot air from the boiler was triggering it).I have only had this for a month or two, so I can't attest to it's longevity. But, so far it works as it should.

I have 24x36 garage and I put the fan on one side and when I open the windows on the other side there is a breeze going through the garage. Also when welding and sanding it sucks the smoke and dust right out. Verry happy.

This fan works so well easy to install added it to my attic to draw more heat out during the Texas summer months
