Ventilation silencer

for air ducts

Silencers for circular and rectangular ducts made of sheet steel. CIRCULAR SILENCER Manufactured with perforated helical inner tube and helical outer tube. The separation between the tubes is filled with acoustic mineral wool with a fiberglass veil on the face exposed to the passage of air, to prevent the insulating material from being carried away by the air flow. We advise you on the calculation and selection of the circular silencer that best suits your needs. RECTANGULAR SILENCER Manufactured with a METU 20 type profile and baffles filled with rock wool panel, with a 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. All our rectangular silencers have technical data, extracted from the test report according to the UNE-EN ISO 11691: 2010 standard to which they have been submitted in the Applus laboratories.
