What an exhaust silencer does

An engine expels the exhaust gas in short pulses. This creates noise in the exhaust line. The silencer reduces this noise before the exhaust gas reaches the open air. At the same time the back pressure for the engine should stay low.

When a new silencer is needed

An exhaust silencer is exposed to hot exhaust gas and condensate. Over the years the shell and internals can rust through. Then the noise at the site increases. A new silencer is also needed when an engine is replaced and the old one no longer fits.

Replacement made to measure

We source the new silencer to the dimensions of the old one: overall length, diameter, position of inlet and outlet as well as connections. So it fits the existing exhaust line.

For the same exhaust line we also supply expansion joints, flanges and catalysts.

Frequently asked questions

Does the new silencer fit the existing line?

Yes. We source it to the dimensions of the old one: overall length, diameter, position of inlet and outlet as well as connections.

What material is the silencer made of?

Stainless steel, usually 1.4301 or 1.4404. We follow the old silencer or your specification.

How fast do I get a quotation?

Within 2 working days you receive a quotation, a question about missing data or the date of our quotation.

Do you deliver throughout Switzerland and abroad?

Yes. Eurolog delivers exhaust silencers to the installation site throughout Switzerland and abroad, for example to Germany, Italy or France. We arrange transport, customs clearance on import into Switzerland and export documents.

Do you also supply silencers that are not listed here?

Yes. The details on this page are examples. We also source other sizes, materials and makes, replacements for older plants and special designs to drawing. For a first enquiry a photo, the nameplate or a sketch is enough.

What we need for a quotation

Engine type and output, the dimensions of the old silencer or a photo of the nameplate, as well as the required attenuation or the sound level at the site. Exhaust gas flow, exhaust gas temperature and permissible back pressure help us, if known. If your part is not on this page, ask us anyway.

We supply customers in Switzerland and abroad. Every export enquiry is checked against Swiss export control and sanctions regulations.
