Industrial Silencers
Vent 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. Widely installed alongside relief and control valves in compressed gas piping systems, our silencers help ensure quieter and safer operation. Available in both concentric annular ring and wrapped Acousti-Tube design, they offer a range of profiles and configurations to meet site -specific requirements.
Effective Noise Attenuation
The durable design ensures a long lifespan, excellent noise attenuation for any high-frequency system and prevents shell radiated noise.
High Compatibility and Flexibility
Silencers are available in standard sizes and custom configurations, many pipe connection styles and for vertical or horizontal installation.
Trusted Single Source Supplier
Commercial and manufacturing locations throughout the world ensure fast delivery, low costs, consistent pricing and reduced complexity.
Product Features of Our Vent Silencers
Our vent silencers are heavy-duty units. The inlet plenum is covered with outer acoustic wrap and lag shell to reduce outer mechanically induced shell noise, and internal flow noise. A highly absorptive acoustic fill material, and heavy gauge perforated face sheets guarantee exceptional attenuation at high frequencies. The inlet nozzle and diffuser are constructed of steel and fully welded. The diffuser provides controlled pressure expansion to atmosphere and uniform flow distribution through the acoustic section of the silencer. Lifting lugs support simple installation while a bottom drain eliminates water accumulation.
Typical Applications for Vent Silencers
Vent and blowdown silencers are rarely a simple catalog selection. For each application, detailed specifications and system description are required for Envanio Universal to provide a silencer best suited to meet your application requirements. Typical applications include:
Typical Industries to Apply Vent Silencers
Envanio Universal designs and manufactures vent silencers to effectively reduce noise. They are engineered to meet the requirements of the following industries, ensuring compatibility form installations worldwide.
Regular Inspections of Your Vent Silencers
Regular inspection and maintenance of vent silencers are essential for employee safety and machinery performance. A malfunctioning silencer can lead to increased noise levels, excessive pressure pulsations, or the release of harmful particles into the environment. Having an industry expert assist with these inspections can help in the early detection of any deterioration, ensuring the safety and efficiency of the equipment.

FAQ
Vent silencers are typically used in conjunction with relief or control valves on piping systems for compressed gases. When gas is released to atmosphere, it can create excessive noise that can be objectionable to surrounding areas. Envanio Universal has particular expertise as a supplier of steam vent silencers for industrial applications and natural gas blowdown silencers (BDS) for gas compression stations during emergency shutdown.
