Cilencer with ogive

COD. 150/duct diameter.

Circular silencers made with an external cylinder in suitably thick galvanised sheet metal and with an internal element in expanded sheet metal.
In between the external cylinder and the internal element there is a sound absorbent pad with a thickness of 50mm, the external diameter of the cylinder is therefore around 100mm greater than the diameter of the connection tube.
When a greater sound reduction efficiency is required, the silencers are made with a sound sound absorbent ogive placed at their centre, see art. 150.
The silencers are built to a standard height of 1500mm, but can be bulit to any height on request.
