The PREMIUM+ range silencers with circular connection are designed to optimize acoustic attenuation in circular ductworks and minimize silencer size.
Intended for commercial building and residential applications, they are equipped with a sound-proofing splitter which decreases ventilation noise level and enhances acoustic performances.
Their aeraulic and acoustic performances have been tested and approved by an independent laboratory (CTTM) according to the standards ISO 7235 : 2009
- Casing : galvanized steel Z 275
- Sound proofing : rot-proof and water-repellent mineral wool
- Connection : male circular connection with EPDM gasket
