ABSTRACT:
A turbine sound reducer for reducing high frequency noise generated by a bleed air discharge from a paint spraying equipment turbine for operation with a non-bleeder gun. The sound reducer includes an enclosure containing inlet and outlet tubes in a spaced, opposed parallel relationship. The enclosure may be part of the turbine housing or it may be an independent closed body. In one embodiment, the inlet and outlet tubes are integrally molded with the enclosure, and a bifurcated, molded barbed fitting is provided to connect turbine bleed air to the sound reducer.
