Abstract: A method of maintaining the internal pressure of an inflatable product utilises control apparatus. An air flow generator, operated by a motor, supplies a flow of air internally to a connected inflatable product. A sensor arrangement monitors the internal pressure of the connected inflatable product and a motor controller adjusts the speed of the motor depending upon the monitored pressure.
