ABSTRACT:
A suction and blowing device exhibits three air conduits connected to a source of pressurized air and partially terminating in a common transport conduit and has a selectable control body located between the air conduit entrance openings and the pressurized air source for regulating the entrance of the pressurized air into the air conduits. The device allows for the selective direction of pressurized air to one or more of the three air conduits to perform completely different functions such as: suction with an injector nozzle, vacuum cleaning using an injector nozzle and an additional cleaning pressure jet, blowing using a nozzle with large dynamic pressure and air velocity, and blowing using an injector nozzle and high air through-put.
