The RIS Series Inlet Silencer
is a heavy-duty, all welded unit constructed of carbon
steel sheet and plate. It features an acoustically
treated outlet and will provide pulse control and silencing
suitable for critical PLV applications. Sizes 4'' and larger
are equipped with flanged connections drilled to 125/150
lb. ANSI specifications. Smaller sizes are standard with
male threaded pipe nipples. Exterior surfaces receive
a shop coat of rust inhibitive primer and may be finish
painted in the field if desired. The RIS Series is the
basic model, having conventional end inlet/end outlet configuration.
A low side outlet version is designated RISY Series and
high side outlet configuration is designated RISH Series.
The three types are fundamentally alike and performance
is identical. Mounting brackets and other options are available.
