This paper describes the experimental study of the aerodynamic characteristics of some modified non-contact type suction devices. The present study has been carried out in collaboration with OHTANI-ENG. The main aim was to reduce magnitude of jet noise. We achieved the subject and that brought about improvement of suction force simultaneously. The force curve vs. supplied compressed air has been obtained by pressure distribution on surface of wall, and the jet velocity has measured by a hot-wire anemometry at edge of the suction device. As a result, the suction force has been improved in case of "With diffuser" at end of pad. However, the improvement is depended on size of valve, that is suggested that we have to consider relation between valve shape and Coanda effect at area of nozzle jet.
