Sound Attenuator & Acoustic Louvre

Overview

Efficient have undertaken rigorous R&D on the products to ensure that they are fit for purpose. Attenuator casings
have been pressure tested up to 2500 Pa to ensure that flanges do not deflect beyond the limits specified within DW/TM1. Our largest spliter elements have been stacked in modules more than 6 m high to ensure they do not deform under their own weight. Splitter attnuators have been tested with airway velocities up to 25 m/s to ensure splitter facing deformation and mineral wool fibre egress is within acceptable limits.
