Through-wall penetration silencers

The STM silencer, entirely made of polystyrene, is installed in all the linings after a circular hole has been made in the wall and a PVC sleeve Ø 125 mm has been sealed. Installation can be done inside the lining with an adjustment sleeve or a front side that can be inspected and removed to facilitate maintenance.

It is associated with an MG 22, 30 or 45 m³/h self-regulating or ISOLA HY humidity-controlled air inlet.
