Where do I position my silencer?

We all experience loud noises at some point during the day. However, too much at once leads to serious damage. Thankfully, we have a range of solutions that can help. Our discharge silencer is especially popular. This isn’t just some standard product; our team designs each unit so that it meets the exact requirements.
First-time users of silencers won’t know exactly where to put them. Ideally, you must position them as close to the noise source as possible. This shall aid you in stopping the sound at its origin. Additionally, it’ll cap noise breakout points along your system. Yet, turbulent airflow typically occurs near noise sources. This includes dampers, valves, and fans. Consequently, users need to assess aerodynamic system effects.

Improved flow conditions

A discharge silencer can actually enhance flow conditions near the fans. This is especially likely if the design is correct. Discharge and special fan inlet silencers lower aerodynamic system effects. Inlet box silencers do the same but they also suppress noise at its source. Their efficient added pressure drop can be moderately negative. This is if the silencer boosts the flow out of or into the fan. As a result, the fan’s performance increases.

Acoustic spots

The mechanical room wall might be the ideal acoustic spot for a duct silencer. The purpose here is to minimise break-in/breakout and duct-borne noise. Nonetheless, you usually find fire dampers here. To compromise, users tend to place silencers within the mechanical room. You may have to put the silencer outside this room though if there isn’t enough space.
At Ventx, one of our most valuable tools is our modern computer software. We use it to produce predictive acoustic models for systems in the design stage. This permits us to fashion a discharge silencer for your operations. As a result clients get fantastic results.

Predicting noise levels in industrial settings

Our team is one of the leading providers of industrial silencers in the country. They can aid you if you’re struggling with a discharge vent. Other applications we cater for include discharging an air compressor vessel as well as silencing a steam boiler. There’s also plenty more our merchandise can help you with.
You may be an engineer that’s tasked with purchasing a vent silencer. There’s a lot you need to think about here. Because of this, things can seem overwhelming at times. It doesn’t have to be like this though. What we’re going to do is talk about the details you must consider. In the end, you should be able to select a suitable product without much difficulty.

How much noise?

The main area you have to look into here is the noise created by the high-pressure discharge vent. For years, researchers have contributed to calculating the noises that come from the high-pressure venting of gases. As a result they have been able to identify key factors they can use to predict the sounds. Below, you can find several examples of these details.

The factors

Firstly you need to look at the mass flow. The greater this is, the more noise the system will generate.
The molecular weight and type of gas is important as well. If your gas is relatively light, the noise will be louder.
Speaking of light gases, high temperatures lead to lighter gas flows. Consequently, everything becomes noisier.
There’s also the matter of upstream pressure vs. downstream pressure. The more excessive the former is relative to the latter, the louder the noises.
At Ventx, we go to great lengths to ensure your silencer performs to acceptable standards. We will start by looking at your unique requirements. Afterwards, we’ll use what we’ve learned to create your product.
If you have a noisy discharge vent to deal with we can be of assistance to you. Please get in touch with us to discuss your needs and find a reliable solution.

Vent and blow down silencer designs are comparable

Depending on your profession, you may need to work in a noisy environment. This isn’t an ideal situation to be in. The longer you’re exposed to loud sounds, the more likely it is that you’ll suffer negative effects such as hearing damage. Our company happens to have the perfect solution. This comes in the form of a bespoke blow down silencer. You can use one to keep noises to a minimum.
Noise is what we use to describe those sounds that we don’t want to hear. One of the largest contributors of unwanted sounds is the lack of suitable maintenance. Equipment that you don’t look after becomes ineffective in time. As part of this it could get very noisy. You need to find the perfect solution if this issue arises.
Two of the most important noise management tools out there are the blow down and vent silencers. You’ll want to make certain that you maintain them properly. That way they will work effectively and make workspaces safer.


We use the terms blow down and vent silencer when referring to the relative application we use them for. The design is comparable for both. This is because we refer to vent silencers when we’re venting at a continual run speed for a set amount of time.
There will be points when the vents are blowing down a limited volume of gas. During these instances, we refer to them as blow down. The gas starts at a high pressure but ends at a lower one when enough time passes.
We size vent silencers for sustained flow. For blow down, the sizing focuses on maximum flow.
At Ventx, we use a combination of experience and quality materials to deliver top calibre merchandise. We serve customers in the UK and abroad. In fact, we distribute almost half of our silencers to clients outside the country. That shows just how excellent they are.
If you would like to discover more or want to order a vent or blow down silencer, feel free to contact us anytime. We look forward to hearing from you.

All About Our Silencers

We often hear a lot about industry’s impact on the environment in reference to lowering our carbon footprint. What is not always given as much attention is the issue of noise pollution. For this problem, at Ventx we have the perfect solution with our industrial silencer design. Particularly considering noise levels in the petro-chemical and service industries, the best way to deal with this issue is through a custom design for individual applications.
Innovative Technology
By using advanced computer software, we are able to craft predictive acoustic models within the design phase, so that silencers can be designed prior to the building of the infrastructure. On the other hand, we can also work with existing machinery in order to plan the necessary measures for noise reduction. Typically, we are able to produce gas ejector silencers, direct line silences, vent discharge silencers, and control valve silencers.
Gas Ejector Silencers
A gas ejector silencer uses either hydrocarbon gas or steam, which can be both vented into the atmosphere or in a closed system in order to reduce any noise being produced. This works by attenuating air-born sound waves circulated in a flowing medium. We calculate the ejector noise and flow mixture in order the determine your specific requirements.
Direct Line Silencers
A direct line silencer differs in that it uses absorption rather than pressure variation to reduce any noise created by machinery. Often used with compressors, they can be offered as a complete unit. Alternatively, an acoustic core can be supplied, which would be inserted into existing pipe work.
Vent Discharge and Control Valve Silencers
Finally, vent discharge and control valve silencers are able to lessen the pressure of the gas flow at the same time as absorbing as much sound as possible. This method makes use of both an expansion camber, and an absorptive core. A vent discharge silencer is design to attenuate the noise level to a required sound pressure level, considering the distance from the silencer. They can be used in high pressure vents, steam vents, safety relief valve outlets, system blow downs, purge outlets and so on.
