Straight-Through Absorptive Silencer
The U2 Series is a standard grade straight-through absorptive silencer available in pipe sizes 5" to 16" which utilizes a lower length-to-diameter ratio. It consists of mild steel construction and is painted with a standard single-coat semigloss light blue alkyd enamel rated for 300°F.
Annular Flow Absorptive Silencer
The SU Series silencer is available in sizes from 4" through 30" inlets and utilizes a lower length-to-diameter ratio. Two concentric perforated cylinders lined with acoustical pack form an annular flow path. It consists of mild steel construction and is painted with a standard single-coat semigloss light blue alkyd enamel rated for 300°F.

Envanio Universal designs and manufactures absorptive silencers to effectively reduce high-frequency noise. Thanks to the different models, our absorptive silencers are suitable for a wide range of industries.
If your industrial application involves high airflow and predominantly medium- to high-frequency noise, an absorptive silencer typically provides the best combination of strong noise attenuation, low pressure loss, and operational efficiency.
To meet individual customer requirements and varying operating conditions, Envanio Universal offers a wide range of standard or custom-built industrial silencers.
Attenuate noise generated by your diesel and natural gas applications with Envanio Universal’s comprehensive line of high-performance primary and secondary engine exhaust 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 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.
