OCTA with Baffle
OCTA with Baffle
The OCTA with baffle sound attenuator strongly attenuates mid and high-frequency acoustic propagation in circular ducting.
OCTA with Baffle
The OCTA with baffle circular sound attenuator very strongly attenuates noise transmitted in the ventilation ducting and therefore ensure acoustic comfort inside commercial and multi-occupancy residential buildings while delivering good airtight performance. A wide range of diameters from Ø 250 to Ø 630 mm.
The + products
- high-performance acoustic attenuation,
