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 pulsating air jet which enters the room horizontally reduces despite the low induction the end velocity of jet and the temperature difference very quickly. This allows the air to be blown into the room without causing draughts.

• 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 using inductance.
• Air throw, horizontal, radially pulsing.
• Suitable for cooling to -10 K.
