SICI series circular silencers are absorption silencers available in two versions: with pod and without pod. The presence of the pod increases the surface sounproof area of the silencer, and therefore its acoustic absorption ability. This solution also generates an increase in pressure losses that must be considered in the design of the aeraulic network.
SICI can also be used to reduce noise emissions of the ejection ducts to the outside, wherever the environmental condition claims this by law.
