Donkin Circular/Rectangular Silencers
In order to maintain noise control performance during operations it is often necesssary to include noise abatement technolgy such as Donkin silencers in the process.

Key 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

Standard 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.

Optional features
  • 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.
