Manufactured with METU 20 type profile and rock-wool panel filled baffles with black veil on the face exposed to the passage of air to prevent the insulating material from being dragged by the air flow, and with an arrowhead termination for a better aerodynamic behavior. The circular silencers are manufactured with perforated helical inner tube and helical outer tube. The separation between the tubes is filled with acoustic mineral wool with fiberglass veil on the face exposed to the passage of air to prevent the insulating material from being dragged by the air flow. Available in different diameters and in lengths of 600, 900 and 1,200 millimeters.
