Slot diffusers direct air from the air conditioning system into the room horizontally or at an angle. The air flow obtained at the outlet of the diffuser allows one to achieve high ejection values, thereby quickly reducing the flow rate and leveling out the temperature difference between the supply air and the air in the room. As a result, there is a mixing of air flows in comfort zones, with a good distribution of air jets throughout the room and a small turbulent vortex in the area where people are present.

Slot diffusers of the VSD50-1-LT series have adjustable guide drums. The direction of air flow can be changed if necessary. The temperature difference between the supply air and the room can range from –10 to +10 K.

Flap blade (optional) to balance air flow simplifies operation.

To create an attractive, holistic room design, the VSD50-1-LT series diffusers can also be used for extract ventilation or supply/exhaust combinations.
