A blowing tool comprises a body part with a connection (8) for pressurized, gaseous fluid, an exhaust nozzle (13) and a valve (9, 10) located between said connection and said nozzle and having an adjustable fluid passage. The nozzle is provided with a plurality of exhaust channels (12) ending near or in the mantle surface of said nozzle and spaced from the central parts of said nozzle. The location of the outlet apertures brings co-ejected air to effectively reduce differences in pressure and velocity between the ambient air and the exhausted gas so that a pronounced lowering of the noise level of the working blowing tool can be obtained. |
