At some point, as an engineer, you might need to come up with a specification in order to purchase a blow down silencer. Due to everything it involves, it may seem overwhelming initially. We are here to tell you that it does not have to be however. Moreover, we want to assist you with making the right choice.


People use these types of silencers for blow down applications. We define these as where your objective is removing high pressure gas. This is from a set volume. Usually, there are time limits and one last blow down pressure. This will be near to the atmospheric pressure, which is typically 50 psig. The most recurring use of our special silencers is on natural gas pipelines and compressor stations. Before you purchase one however, there are certain details you have to know.

The necessary details

Firstly, we have pressurised volume. This is essential because larger volumes demand bigger silencer models.

Maximum blow down time is also important. Longer times allow you to employ compact silencers. In emergency blow down circumstances, the total acceptable blow down could be 60 or 180 seconds.

There is the final blow down pressure as well. You might end up specifying a pressure of 50 psig. If you do, it will become harder to match the time specification using an economic silencer selection.
