ECTA RECTANGULAR SOUND ATTENUATOR
Fresh air intake
The ECTA rectangular sound attenuator strongly attenuates low, mid and high-frequency noise propagation in rectangular ducting.
ECTA RECTANGULAR SOUND ATTENUATOR
The ECTA rectangular sound attenuator attenuates noise transmitted in the ventilation ducting and therefore ensures acoustic comfort inside non-residential and multi-occupancy residential buildings. The baffle is 100 mm or 200 mm thick and its L x H dimensions may be between 300 and 2400 mm.
The ECTA comprises a single-piece panel made of 100 mm or 200 mm thick mineral wool which strongly absorbs noise. To maximise attenuation, several should be installed in series inside a ducting element.
