Abstract: The blower motor is powered by 115 volts from the circuit board that runs all of the other functions of the machine. This blower assembly is designed with enough draw to pull the incoming air across air filters in order to keep the blower and the operator free of air-borne debris. The filtered air is then supplied into the hollow framing of the equipment to be distributed to the operator, circuit boards and motors through holes made in the equipment framing. Using the machine frame as the ductwork also preserves the style and design of the equipment. Not only is this a new idea to the exercise equipment industry, but I believe it is necessary for an exercise machine to deliver clean air to the operator in order to keep their good health in mind. A blower without an air filter will send bacteria onto the user who is breathing heavy and sweating. This seems to defeat the purpose of exercising and the benefits of getting your heart rate and breathing accelerated for a length of time.
