Description and function

The PRQX is a supply air diffuser featuring a square front plate with integrated, manually adjustable air deflectors positioned in a circular arrangement. By changing the angle of the deflectors, the airflow pattern can be adjusted from swirl-like horizontal to vertical, without changing the overall pressure drop through the slot openings. This ensures consistent balance across the system. For extract air applications, the PRQX diffuser is supplied without air deflectors. The recommended maximum temperature difference (Δt) for cooling applications is -10°C.

For PRQX 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 600x600 mm.

Applications

The PRQX diffuser is suitable for comfort and light industrial ventilation purposes, such as office building, schools, retail stores, hospitals, storage facilities and more.
