ABSTRACT:
The radon removal system includes one or more pipes coupled to the source of radon gas beneath the basement floor in a building. The pipes are coupled through the side wall of the basement to a fan which draws the radon out of the basement and away through piping coupled to the fan housing. The fan has a DC motor which is current limited to improve its operation. In addition, a vacuum switch is provided in the fan housing to sense proper operation of the fan. The switch is coupled to a signal light at the power cord inside the basement to indicate when the fan is operating properly.
