Varispeed 300watt Fan Controller

A good cheap way to turn your fans down in the winter and up in the summer. Its easy to use just plug in the wall and plug your fan in on top, dial is used to then turn your fan up and down. It will create a slight hum or buzz from your fan. Can be used with inline fans like the system air Rvk up to 8" or 300 watt. DO NOT USE with heaters or big fans as this can not handle them. Anything bigger we would recommend looking at an SMS Fan Controller.
