Broad band silencer

The acoustics of the system are improved by reducing inlet noise and sound radiation from the ducts. On the inlet side, the compressor and flow noise from the stack and humidifier are the noise sources.



The MANN+HUMMEL broad band silencer dampens the intake noise caused by the compressor and reduces flow noise from the stack and humidifier. Various technical solutions and acoustic measures are used to improve the acoustics of the system.

Product benefits

  • Damping of compressor generated inlet noise
  • Pressure loss optimized product design for low energy consumption 
  • Design adaptable to customer-specific needs and requirements of the project
  • Acoustic function can be integrated in parts like the water separator or air intake system
