Modular Acoustic Rectangular Silencers

Description

Modular Acoustic Rectangular Silencers for industrial noise control

If you have an acoustic enclosure to reduce unwanted machine plant noise then you are likely to need these.

When suitably chosen they allow for adequate airflow, both in and out, which most machines require.

To provide sound damping they have acoustically lined cells to help absorb the unwanted noise.

This in turn means they impede the airflow somewhat so they need to be rated large enough to maintain both acceptable pressure drops and airflow.

Options can include:

Mouths
Anti-bird mesh
Rain hoods
Flat rain covers
Swan neck rain covers
