Diffusers are most important for the performance of A/C and ventilation systems in the room Application The Displacement Diffuser DLQ was specially designed for: - Foyers and entrance areas Sports arenas and crowded areas Work areas where ventilation from above is not possible Areas where inductive ventilation is not wanted Work areas with extreme heat loads and elevated levels of contaminants The LTG Displacement Diffuser type DLQ can be installed at a height of up to 3- 4 m, or on the floor. The airflow connection can be from below or from above. With the Displacement Diffuser type DLQ, LTG...
