Silencer Types|Principles

Print PDF

AXCES has a wide range that covers all applications and engine sizes. These silencers are divided in series depending on the application, damping technique and the desired damping levels.


Absorption Type

 

The noise is absorbed by specific acoustical fibre inside the silencer. The Absorption Type silencer is most effective in the middle and high frequency range.

 

Reflection Type


The noise is reduced by creating a gas flow through separate chambers in the silencer. The Reflection Type silencer is most effective in lower and middle frequency range.

 

Reflection|Absorption Type


The Reflection | Absorption Type silencers are based on a combination of absorption and reflection damping techniques in order to reduce the noise in the complete frequency range.


 

Silencer Types With Integrated Spark Arrestor


Axces silencers can be equipped with an internal spark arrestor. Axces spark arrestors are DNV and RMRS type approved.


 

Spark Arrestor with damping


Axces has a wide range of Spark Arrestors with Damping which can be mounted in the exhaust gas system. Axces spark arrestors are DNV and RMRS type approved.

 

Spark Arrestor



Axces has a wide range of separate Spark Arrestors which can be mounted in the exhaust gas system. Axces spark arrestors are DNV and RMRS type approved.

Pipe Diameter

The silencer size is important as well as the pipe diameter of the exhaust system. We will calculate the optimal diameter and silencer for your engine.

Damping Level

  • The noise reduction varies from 18 dB (A) until 45 dB (A).

Frequency

  • The frequency range on which this silencer is most effective.

Application

  • Some silencers have a specific application where others can be used for more purposes.

Custom Made

  • AXCES can also produce specific Silencers. Custom made silencers are not described here.

Fully Integrated Exhaust systems

You can find all of our products in the "Complete Exhaust System and Emission Technologies Webshop". This online facility gives AXCES’ clients direct access to more then 2.500 parts related to the exhaust gas system. This site enables exhaust parts to be searched for and selected by goods and  direct quotes can be done online.
 

3D Model - Item Finder

Axces is trying to make it easier for you to find the item / part of the exhaust system you are looking for, with a new Flash application. The base of this application is a interactive 3D Model of a complete exhaust system. Simply roll over the part in the system you want to know more about and more information will be directly presented to you. Launch the 3D Exhaust System Flash application.
