The silencers shown below are more fullydescribed on the individual catalog pages.These units are designed specifically for useon Rotary Positive Blowers.There are fundamental similarities betweenblower silencers and other types, particularlyreciprocating engine silencers, which alsorequire a silencer design that provideseffective pulse control as well as noiseattenuation. However, blower silencersgenerally must be constructed moreruggedly to withstand prolonged exposure tosevere pulsations produced by the blower.All silencers described are of standard withend in, end-out design. Low or high sideinlet and outlet connections are availableand are described on the individualcatalog pages.GeneralInformationRotary Positive Blowers2.2 2.2Rotary Blower Positive SilencersBlower SilencersUCI SeriesInlet SilencerChamber-type inlet silencer for use on subcriticalPLV applications.
