Silencers are made with galvanised bent sheet metal containing sound absorbing, incombustible and rot-proof materials, remaining intact over time. They are protected by dust-proof glass cloth and held in place by stretched sheet metal. Among the primary features of our silencers is their ability to allow airflow with minimal pressure drops while at the same ensuring reduction of noise generated by systems or the flow itself due to the speed of the air. They are therefore used to silence system fans and in air ducts, extraction chimneys, or other similar air systems.
