OCTA with seals
OCTA with seals
The sealed Octa sound attenuator strongly attenuates mid-frequency acoustic propagation in circular ducting, with low leakage.
OCTA with seals
The sealed Octa circular sound attenuator 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 125 to Ø 1000 mm .
