All chrome, all metal fan with heavy duty 12 volt motor dresses up the interior of any horse stall area. A 2-speed switch mounted on the base allows for convenient high-low, on-off operation. We can wire this into your trailer to work off a switch, perfect in hotter weather or when stuck in traffic. We have found that the horses ride a lot quieter with the "white noise" also. Nice low hum when on, able to be adjusted left to right to accomodate the horses in the trailer. We suggest either 1 per horse stall or 1 at the rump side where the divider latches, per divider.
