The U2 Series is an economical straight-though
silencer for applications requiring lower-degree
noise attenuation. It is fundamentally similar to
the U5 Series, but has lesser attenuation due to
its relatively low length to diameter ratio. Mild
steel construction, primer-coated exterior.
Common Applications
intermediate size rotary positive
blower inlet
centrifugal blower inlet or discharge
intermediate size dry vacuum
pump discharge
gas turbine inlet
high-speed centrifugal compressor inlet
high frequency noise sources
Note:
U2 series standard paint and acoustical
packing are suitable for 325°F.
