Noise attenuation section

Design and application

- The sound attenuator section consists of sound attenuating couplings and a casing.
- The sound-absorbing elements (couplings) are 140 mm thick; the filling of the couplings is sound-absorbing non-combustible mineral wool with a density of 60 kg/m3 and 80 kg/m3.
- Wicket body: galvanized steel frame.
- Outer surface: thin fabric which prevents mineral wool particles from getting into the air flow.
- Number of couplings in the sound attenuator section: 2÷13 depending on the unit size


Features

- Maximum air flow rate: 5m/s.
- Operating temperature: -40 ÷ +70°C.
