Description and function

The DRTX is a supply air diffuser featuring a square design with integrated, manually rotatable plastic nozzles positioned in a square arrangement across the front plate. By simply rotating the aerodynamically shaped nozzles, the airflow can be adjusted from a swirl-like horizontal pattern to unidirectional, bidirectional, or vertical distribution patterns. When properly designed and deployed, the DRTX operates draught-free at low acoustic levels, ensuring a comfortable indoor environment. The recommended maximum temperature difference (Δt) for cooling applications is 10°C.

For DRTX 400 and 500 sizes, where the outer frame dimension of the diffuser plate is smaller than 595x595 mm, we recommend using the SI type adapter, to match the standard suspended raster ceilings dimensions of 595x595 mm.

Applications

The DRTX diffuser is recommended for comfort ventilation purposes, such as office building, schools, retail stores, hospitals, warehouse and more.
