The silencers are designed to reduce the noise level.

They allow the noise level of the fluid to be attenuated so as to reach acceptable levels in civil and industrial environments.

To reduce noise pollution Mirolli Srl offers two series of silencers:

Circular Silencers

There are two constructive versions, silencers with ogive and without ogive

The first version has a better attenuation capacity as they have a greater sound-absorbing surface than the version without ogive.

They are made with an external casing in galvanized or painted sheet metal flanged at the ends.

The materials can be defined according to the specific requests from the customer.

Rectangular silencers

They are made with an external casing in galvanized or painted sheet metal flanged at the ends.

The sound-absorbing partitions consist of a galvanized sheet frame with mineral wool inside, protected by fiberglass and galvanized perforated metal-mesh.

The materials can be defined according to the specific requests from the customer.
