Air diffuser LDB 12style

Overview
The slot diffuser LDB 12style (LTG System clean) supplies rooms with fresh air by generating highly inductive individual jets for rapid mixing of supply and room air. The diffuser is made entirely of metal for improved fire protection, vandalism resistance and sustainability. Its narrow profile suits high architectural demands and is suitable for rail vehicles and integration into system ceilings.
