The machine contains an air blower which, depending on the option chosen by the user, blows air into or draws air out of inflatable equipment, which is achieved by means of automatic i.e. controller-operated solenoid valves opening or closing. The air blower is housed in a housing that can be placed in a specific location (beach, hotel, etc.) near the place where the inflatable equipment is used. The machine is intended for self-service, the air blower being connected to a hose with extensions to fit the valves on the equipment.
