Dimensions are similarto standard models, but material typesand thicknesses are selected to meet coderequirements. Prices are quoted on application tomeet your pressure and temperature conditions.SURS Series blower silencers are heavy-duty, allwelded steel construction, suitable for applicationas either and inlet or discharge silencer on rotarypositive. These units are designed for blowersrunning above critical transition speed, andtherefore, no acoustic packing material is includedin the design. Instead, these units have a speciallydesigned, high-performance, three chamber systemwhich incorporates a diffuser on the blower sideof the silencer units. The unit will provide excellentpulse control and is designed for themost demanding applications.Sizes smaller than four inches are equipped withstandard male threaded pipe nipples, while the 4"and larger units have flanged connections drilled to125/150 lb ANSI specifications. The SURS Seriesemploys a high-heat aluminum paint system.The SURS is a basic end-in, end-out configuration.A low-side inlet model is designated as the SURSYSeries; the SURSY is fundamentally identical to theSURS SeriesSURSY Series(Low Side Inlet)SURS series in both dimension and attenuationperformance. Both series are designed to operateat pressures to 15 psi. Mounting brackets, shelllagging and other accessories are available for bothseries of blower silencers.YYKKCombination Chamber Type Multi-Use Discharge SilencersSURSSURSYModel Part Model PartSURS-2SURS-2.5SURS-3SURS-3.5SURS-4SURS-5SURS-6SURS-8SURS-10SURS-12SURS-14SURS-16SURS-18SURS-2055-A02-SS55-A25-SS55-A03-SS55-A35-SS55-A04-SS*55-A05-SS*55-A06-SS55-A08-SS55-A10-SS55-A12-SS55-A14-SS55-A16-SS55-A18-SS55-A20-SSSURSY-2SURSY-2.5SURSY-3SURSY-3.5SURSY-4SURSY-5SURSY-6SURSY-8SURSY-10SURSY-12SURSY-14SURSY-16SURSY-18SURSY-2055-B02-SS55-B25-SS55-B03-SS55-B35-SS55-B04-SS*55-B05-SS*55-B06-SS55-B08-SS55-B10-SS55-B12-SS55-B14-SS55-B16-SS55-B18-SS55-B20-SS*Specify -TT for male pipe threaded units.P D L N H22.533.545681012141618201212121414*16*18263036364248484040465959717211113613816818118821433333333.53.53.53.53.53.54.534344053536566104129131161174181205YK Min.
