Silencers

SN 112 Medium Duty Absorptive Industrial Silencer

These silencers can be used on either diesel exhausts or air systems.

SN 114 “Residential” Type Silencers

These silencers incorporate an expansion and multi pass section to attenuate the lower frequency sounds, and a sound absorption section to attenuate the higher frequency sounds.

SN 115 “Medium Duty” Exhaust Silencers

These silencers incorporate a multiple pass section to smooth the gas flow and a sound absorption section to attenuate the higher frequency sounds. They are suitable where moderate sound attenuation is required, but where space is limited.

SN 116 “High Attenuation” Exhaust Silencers 

These silencers incorporate a multiple pass section to smooth the gas flow and a sound absorption section to attenuate the higher frequency sounds.

SN 120 “Multipath” or “Reactive” Industrial Duty Silencers 

These silencers are designed on the reactive principle with twin chambers in which the exhaust gases are mixed and smoothed, thus absorbing a high proportion of the acoustic energy without causing excessive back pressure.

SN 121 “Multipath” or “Reactive” Medium Duty Silencers 

These silencers are designed on the reactive principle with twin chambers in which the exhaust gases are mixed and smoothed, thus absorbing a high proportion of the acoustic energy without causing excessive back pressure.

SN 122 “Multipath” or “Reactive” Residential Duty Silencers 

These silencers are designed on the reactive principle with twin chambers in which the exhaust gases are mixed and smoothed, thus absorbing a high proportion of the acoustic energy without causing excessive back pressure. They can also be used as a primary silencer in a multi-silencer system.

SN 126 “Maximum Attenuation” Silencers 

These silencers are recommended for use on diesel exhaust gas lines where noise levels have to meet the most critical specifications, without creating excessive back pressure.
