Rectangular mufflers

Rectangular mufflers are designed to reduce the aerodynamic noise propagating through the air ducts of ventilation systems. Such noise is generated by fans and other elements of the system.

Muffler body and plate frame are made of galvanized steel.

Plates are filled with non-combustible sound-absorbing material with a coating, which prevents material particles from entering the air duct.

Recommendations for use

In order to achieve maximum noise reduction efficiency, it is recommended to provide a straight-line plot of at least 1 m in front of the muffler.

The maximum air speed between the backstage should not exceed 20 m / s.

For a more effective noise reduction, it is recommended to install two mufflers one by one.
