Multiflow Attenuators - MFB / SIL Series

Multiflow Attenuators Series


  • Silencer overall length includes a 300mm long plenum section which should be fitted to the fan flange when silencers/fans are coupled.
  • This aids the airflow entering/exiting the fan unit and minimises flow disturbance and losses.
  • Alternative silencer lengths are available to special order, together with Melinex lining to baffles.
  • The illustrated insertion losses will vary under such cases - please consult Elta Fans.


  • The units are rigidly constructed and consist of a galvanised sheet metal casing containing a series of centre and side splitters.
  • End flanges are of the Ductmate type to allow easy fixing to the Multiflow Series, of fans and ductwork.
