SN 112 Medium Duty Absorptive Industrial Silencers 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.

SA 125 "Multipath" or "Reactive" Spark Arresting 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. The spark arresting section is designed on the vortex principle, and solid particles are seperated from the gas and deposited in the box.

SN 126 "Maximum Attenuation" Silencers These silencers are recommended for use on diesel exhaust gas lines where noise levels have to meet the most critacal specifications, without creating excessive back pressure.
