Model DF Discharge Silencer

Model DF Fan Discharge Silencers

We have designed a series of fan discharge silencers for use when the fan inlet is connected to the process and the discharge is to the atmosphere.

The pressure drop at the rated flow is 1.00" of water. This pressure drop has been corrected for the pressure recovery from the fan discharge velocity. A 50% diffusion efficiency is assumed for the transition from the fan to the silencer.

Model DF silencers can be supplied, at extra cost, with removable internals for cleaning. This is recommended when the silencer is used with dirty gasses.

The silencers are generally larger than the fan discharge requiring a transition from your fan discharge to our silencer. This transition can be ordered with the silencer.
