Ventx Industrial Vent and Inline Silencers

Ventx lead

Ventx is a major supplier of industrial vent silencers and inline industrial silencers. We offer a bespoke design service to ensure each silencer is manufactured to meet the customer’s specific requirements.

Noise is a particularly difficult factor to predict. An advanced computer program is at the core of Ventx’s silencer design procedure. This specially created program allows us to see the noise level most likely to be created from the customer-provided data. However, it is not as simple as having a computer program. A proven noise-reduction solution is provided through the interpretation of data, combined with Ventx’s experience.

Industrial silencers

Drawing on over 40 years of acoustic knowledge and 30 years of quality silencer manufacturing, a Ventx industrial silencer uses a combination of diffuser design and an absorptive core section. Our designs are guaranteed to meet the noise attenuation required and this guarantee extends to all workmanship.

Atmospheric vent and inline silencers

Atmospheric vent silencers are the essential component when venting steam, air, nitrogen or other gases, and are designed to reduce valve noise to whatever level the customer requires. There are two types of Ventx inline silencers: the first is for used with a control valve and offers pressure and noise reduction; the second type offers minimal pressure loss and is used on compressors’ inlets.

Silencers for pipes, vessels and steam, gas and air ejectors

Ventx also designs and supplies a cost-effective silencer solution that can be fitted inside customer pipe work or vessels, along with silencers for steam, gas and air ejectors.

Industrial silencer design

Ventx designs each industrial silencer to reduce the noise level to the required sound pressure level specified by the customer. Silencer design is constrained by the flow conditions and the overall performance required. Ventx’s industrial silencers have a basic design principle that enables us to supply the best solution for the customer.

Atmospheric vent discharge silencer

Atmospheric vent discharge silencers (VDS) from Ventx are manufactured using a combination of diffuser designs and an absorptive core section. The gas and noise enter the silencer through a multi-hole diffuser and then expand through many holes into the expansion chamber.

These units can be designed to be mounted vertically or horizontally, and are available with optional bird screens and weather-hoods.

Control valve silencers

The design of Vendx’s control valve silencers (CVS) employs the same principle of acoustic design as a vent silencer. This type of silencer is usually designed to a pressure code. If requested, Ventx can design to ASME B31.3, ASME VIII or PD5500.

Direct in-line silencers

Direct in-line silencers from Ventx are designed to produce as little pressure loss as possible, but achieve the required attenuation using only an absorptive section.

These units are often found on compressor inlets and outlets, and can be designed to a suitable pressure code. Direct in-line silencers can be supplied as a simple acoustic core for inserting into the customers pipe work or vessel.

Steam or gas ejector silencers

Ventx provides steam ejector silencers (SES) or gas ejector silencers (GES), which are specifically designed for use with steam or gas ejectors. Ventx calculates the ejector noise and flow mixture.

As customer requirements vary, Ventx is always available to discuss any specific requirement.

Silencers that meet relevant noise standards

Ventx’s industrial silencers meet the relevant noise standards, including the Control of Noise at Work Regulations 2005 and Environmental Noise (England) Regulations 2007.

About Ventx
