Air diffuser LDB 50 maxx

Overview
Slot diffuser LDB 50 maxx designed for particularly high ceilings and large air volumes. Adjustable for constant or variable volume flow with a range of 100–20% without additional mechanics. Blow-out direction adjustable by 180°, factory-preset and reproducible; adjustment possible after installation, including near-closed positions. Roller-shaped outlet elements (Ø50 mm) and an air-optimized inner contour provide high induction and rapid reduction of outlet velocity and temperature difference.
