Other characteristics


SQUARE SILENCERS RAS silencers are used in aeraulic systems to reduce the noise generated by fans and carried along by the airflow. They have galvanised steel casings, with perimeter flanges drilled in all four corners and contain noise absorption panels, sized accordingly and of a thickness that will depend on the noise requirements, made from a galvanised steel frame enclosing mineral fibre panels coated with a glass veil, inflammable with reaction to fire class A1. The panels have aerodynamic edges on the air intake side, to ensure lower pressure drops. This is the only range of silencers available in 18 different models, with units from 275 to 700 mm and ranging in length from 600 to 3000 mm.
