Stack Insert Silencers

Model Designation SIS or VSDS

This type silencer can be of the splitter type (Model SIS) or our specially designed multitube arrangement (Model VSDS), which has a higher attenuation per foot of length than the traditional splitter silencer.

Special mounting features allow the Model VSDS silencer to be dropped into the stack, positioned at the exit end of the stack. This reduces installation cost and time as the silencer hangs from the top edge of the stack. Maintenance costs are also reduced as the silencer can be easily removed for cleaning or inspection, as required.

Pressure drop can be tailored to customer needs more easily with the high performance multitube silencer Model DSVS.

Common materials used for these silencers are: SS 409, SS 304, and galvanized steel (flow temperatures below 400 F)

Fabrication is sub-contracted to pre-qualified fabricators.
