DF3 Silencer

The DF3 silencer is compact and is used to discharge to the steam trap outlet of the inlet condensate return line. It reduces the noise and water hammer problems caused by rapid cooling of flash condensate at the trap discharge outlet.
The main body of the silencer is made of SS304, the inner part is stainless steel, and a filter device is installed at the inlet.
