Applied Vacuum vent and blowdown silencers find application in noise reduction of steam and other gases discharging to the atmosphere.
The source of the discharge is usually a relief valve venting to atmosphere or continuous emission of waste steam or other gases to atmosphere. The silencers can be fabricated to any required construction code and in any required materials of construction. The standard version is extremely robust.
The silencers are of the reactive, absorptive type. The incoming fluid stream enters a plenum chamber and passes through a number of perforated plate tubes set into a tube sheet. Each tube is surrounded by a fine stainless steel mesh whose function is to prevent the surroundings acoustical packing material from being dragged through the tube perforations.
The tubesheet bundle is removable to replace sound medium if required. A rainhood is supplied as standard. The rainhood is also removable.
Our silencers are mostly designed with a slip-ring configuration which allows for free movement of the incoming steam pipe in both horizontal and vertical direction. This allows for zero load of the inlet pipe under thermal expansion.
The advantages of our silencers include:

The advantages of our silencers include:
- The stainless mesh provides an extra long working lifetime.
- The mineral wool is temperature suitable.
- An extremely robust construction.
- Both the rainhood and the tube bundle are removable.
- A slip ring entry flange prevents problems with thermal expansion.
