DucoGrille Acoustic N 150
- Recessed mounting louvre without flange
- Sound absorbing up to 11 dB
- High airflow
The DucoGrille Acoustic N 150 is a sound attenuating built-in wall grille, crafted from extruded aluminium profiles. The louvre blades are locked into place fast and easily on plastic blade holders, and are fitted with sound-attenuating, inflammable mineral wool on the inside. Thanks to its solid construction, the DucoGrille Acoustic N 150 has a high damping value and a low resistance factor (and consequently a better flow rate).
