We manufactured our first Blow-Off-Silencer in 1950. In 1970 we changed our design to the diffuser principle, which shows certain advantages compared to the earlier absorptive design.

The left picture shows the early absorptive design.

The right picture shows the Glaunach diffuser design, with substantially smaller dimensions and also a less weight.

Glaunach silencers are designed to allow uninhibited thermal expansion, without putting uncontrolled stress on its rigidity. The compact and round construction suppresses possible vibration which would cause damage to the silencer after certain time.
