Air diffuser LDB 12 Clean

Product overview
Slot diffuser designed for high occupant comfort and accurate airflow distribution. Adjustable for constant or variable volume flow; outlet elements allow regulation from 100…20% of nominal flow without additional mechanics. Discharge direction is adjustable by 180°, factory-set with reproducible positioning; subsequent in-situ adjustment and nearly closed settings are possible.

Air diffusion
Roller-shaped outlet elements with an air-optimized inner contour produce high induction, quickly reduce outlet velocity and minimise temperature differences in the occupied zone.
