Description

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.

Standard sizes

400, 500 and 595

Airflow range

100 - 700 m³/h

Materials and finish

The front plate and the SI adapter are made of galvanized steel, powder-coated in RAL9003 white color. The nozzles are made of polypropylene.

Optional accessories

• TLS: A compact commissioning box with a circular connection, specially developed for DRTX, PRCX, PRQX and PRNX type supply air diffusers. The solution is ideal for ceiling installations, integrating well into monolithic and raster ceilings, as well as for suspended, free-hanging systems.
• SI adapter: The external dimensions of the optional SI adapter are the same as the standard 595x595 mm ceiling insert. On request, we can also provide a 620x620 mm SI adapter for a 625x625 mm grid ceiling.
