Straight-Through Silencers
Many turbocharged engines and some naturally aspirated engines require very low exhaust system back pressures for maximum performance. For these engines, ET Series Silencers are recommended to provide adequate silencing while imposing negligible restriction on exhaust gas flow.
Spark Arresting Silencers
Operating locations exist where fire hazards and safety codes require removal of sparks from exhaust gases. Our ES Series Silencers are engineered to perform the dual function of spark arresting and silencing for all internal combustion engines. Large capacity spark traps are provided on each unit which can be easily opened for periodic cleaning.
Pressure Drop Coefficient of 4.2 C
Flanged connections to match ANSI specifications
Single-coat aluminium rated for 1000°F
Multi-Chamber Cylindrical Silencers
QS Series Silencers are designed for engine applications that require higher acoustic performance in a cylindrical configuration. They have a high-performance internal design incorporating both reactive and absorptive features that deliver excellent broadband attenuation.
Pressure Drop Coefficient of 5.0 C
Wide range of flanged connections
Up to 50dB attenuation
Puck Silencers
QSN Series Silencers are designed for engine applications that require good acoustic performance in an economical, low-profile package size to fit inside enclosures. They can be installed directly above the engine for simplified pipework. QSN7 and QSN8 are low shell temperature designs with internal shell insulation for lower shell temperature.
Wide range of flanged connections
Custom inlet configurations available
Coat of heat-resistant paint
Oval Silencers
QSE (Single-Inlet) and QSF (Dual-Inlet) Series Silencers are designed for engine applications that require higher acoustic performance in a low-profile package size to fit inside enclosures. All are low shell temperature designs with internal shell insulation for lower shell temperature and excellent attenuation.
Wide range of flanged connections
Custom inlet configurations available
Coat of heat-resistant paint
Each engine and each operating location requires a unique combination of silencer properties. To help you select the right silencer type and size to meet your requirements, Envanio Universal offers an extensive line of engine exhaust silencer models.
Envanio Universal designs and manufactures engine exhaust silencers to effectively control noise. Thanks to the different models, our engine exhaust silencers are an ideal solution for the following industries.
First of all, a grade of silencing is chosen that will satisfy the noise requirements unique to each engine and location. Each of our silencer models offers different noise attenuation characteristics. Secondly, the silencer size is selected to accommodate the specified volume of exhaust flow without imposing excessive back pressure. The open flow area within the silencer should be large enough to accommodate the maximum possible exhaust flow without exceeding the engine manufacturer’s maximum allowable back pressure. Improperly sized silencers may cause loss of power or damage to the engine.
To meet individual customer requirements and varying operating conditions, Envanio Universal offers a wide range of standard or custom-built industrial silencers.
Attenuate noise and pressure pulsations generated by your centrifugal, positive displacement, helicoil, and two- or tri-lobe blowers with Envanio Universal’s comprehensive line of blower silencers.
Attenuate the mid- and high-frequency noise generated by your high-speed centrifugal blowers, fans and compressors with Envanio Universal’s comprehensive line of absorptive silencers.
Attenuate noise generated by high-velocity air, steam, and gas venting applications as well as blowdowns to atmospheres under sonic or critical flow conditions at the valve with Envanio Universal’s vent and blowdown silencers.
Remove liquids from gas-flow vacuum systems serving liquid-sealed rotary positive displacement blowers and liquid ring vacuum pumps with Envanio Universal’s vacuum pump liquid separator-silencers.
Designed and manufactured to meet ASME standards for applications with vacuum exceeding 20 inches of mercury, our ASME code silencers handle operating pressures ranging from 15 to 3,000 PSIG and deal with hazardous or flammable gases.
