Plastic case tube fans with built in thermostat and temperature controller. The fan has an idle speed to always maintain negative air pressure. It will then automatically adjust its speed through three higher speed settings to maintain the desired temperature.
The control system is integrated into the unit and completely wired. Speed control is done by winding taps, so there is no extra noise caused by a controller.
