Vent Silencers – From Glaunach

During the expansion of gas, steam or air, noise pollution develops.  Vent Silencers are mounted after relief valves to reduce the levels of noise pollution. Such equipment is needed in power stations, petrochemical, chemical or similar plants.

Glaunach is only engaged in the design, production and marketing of the blowoff silencers.  Glaunach uses diffuser technology, which allows for compact construction in a small and lightweight design while still allowing for optimum noise reduction. Special equipment had been provided to permit a quick production of prime quality. Today over 6000 Glaunach silencers in more than 80 countries are in use, with no reported failures.

Glaunach Industrial Silencers


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 early 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.

The Glaunach diffuser design

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.
