Multiflow Attenuators Series

Features

Silencer overall lenght 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 lenghts are available to special order, together with Melinex lining to baffles. The illustrated insertion losses will vary under such cases - please consult Elta Fans.

Construction
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.
