ABSTRACT:
A silencer device for attachment to a nozzle, or a combined nozzle and silencer, are provided for reducing the noise generated by compressed air or a compressed air-particulate mixture exiting from conventional nozzles of the type used for air blasting, sandblasting, or peening operations. The silencer has a bore of substantially constant diameter which is, within limits, larger than the nozzle bore for which the silencer is designed.
