An exemplary foam dispenser included a housing, a reservoir for holding a foamable liquid, a motor, a motor shaft, and a turbine air pump. The turbine air pump is connected to the motor shaft. A cam is also attached to the motor shaft and is used for driving a liquid pump. Liquid from the liquid pump and air from the turbine air pump are mixed in a mixing chamber and dispensed through an outlet nozzle. The touch-free foam dispenser further includes a sensor for sensing an object, circuitry for receiving a signal from the sensor indicative of an object being present and circuitry for energizing the motor to dispense fluid in the form of a foam.
