Supply and return air systems can be used in comfort rooms, such as offices for cooling up to Δt= – 10K. Mounting height 2.6 – 4m.

The high induction of the swirl jet produced by the louvre layout reduces the end velocity of jet and the temperature difference very quickly. This allows the air to be blown into the room without causing draughts. The air jet direction can also be adjusted manually later on. The free cross-section is the same in all louvre positions, so that pressure loss and volume level do not change when the throw pattern is adjusted.

• Combined ceiling diffuser for supply air and return air.
• Square faceplate made of sheet steel with powder coating in RAL 9010 (white).
• Suitable for VAV systems with variable volumetric flows.
• Outer area for bringing supply air into the room.
• Inner area for extracting return air from the room.
• Supply air is introduced with high inductance via blades arranged in a circular pattern.
• Suitable for cooling to -10 K.
