ABSTRACT A silencing system is provided for an air-operated pump which also eliminates icing of the pump at higher cycle rates and humidities. The exhaust from the air motor powers an air flow inducer Lo induce a flow of relatively warm ambient air. The induced flow of ambient air is drawn across cold components of the air motor, and the mixed (ambient and exhaust air) exit stream routed away from the air motor. The relatively warm mixed air exhaust flow also allows noise reduction by conventional acoustical techniques without suffering performance degradation due to icing.
