Review on 🌀 iLIVING ILG8SF24VC 24-Inch Variable Speed Shutter Exhaust Fan - Wall-Mounted, Silver by James Mayfield

It was installed in a 45ft trailer ie a metal warehouse (actually a new unused shipping container) which gets very hot in the summer months when closed allowing hot air to be exhausted and fresh air from outside is supplied. to ventilate this device. The thermostatic control makes it very easy to use, and a 3-position switch can be used to switch to manual control. Large aluminum ventilation openings open when switched on and close automatically when switched off. Worked perfectly, I'm very happy with my purchase.
