​In order to maintain noise control performance during operations it is often necessary to include noise abatement technology such as Donkin silencers in the process. Key Features Rectangular inline sound attenuators. Increased low frequency attenuation. High noise insertion loss for maximum sound attenuation. Manufactured from pre-galvanized material with the option of heavy casings for high pressure applications. Low pressure drop due to aerodynamic splitter caps. Units are manufactured from pre-galvanized material. Infill material kept in place with galvanized wire mesh. Special construction material grades. Heavy welded construction. Units are also available in clean seal and Melinex lined. Outer casings are also available in other material grades. Benefits ​The pressure drop through the units are marginal and can be assumed as the same equivalent on a straight duct. ​More uniform attenuation over the acoustic spectrum. ​Low pressure drop due to aerodynamic POD design. ​Various internal linings to suit a wide range of applications. Applications ​​Noise reduction and control.
