Ceiling swirl diffusers with a round front panel, with manual or motorized air flow control for optimal air distribution in the work area in cooling and heating modes

• Standard sizes 315, 400, 630, 800
• Air flow level 65 – 1080 l/s or 234 – 3888 m³/h
• Front panel made of powder-coated galvanized sheet steel and aluminum
• For supply air
• For systems with variable and constant air flow
• Rapid equalization of temperatures and reduction of air flow speed is achieved due to the high level of ejection
• The direction of air supply is changed manually or using a drive
• Diffuser face with streamlined contours for better aerodynamics
• Ideal for rooms with high ceilings

Description

Ceiling swirl diffusers in air conditioning systems create a vortex supply of air for good mixing with the room air. 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. Ceiling swirl diffusers are used for high air flows. 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.

The position of the guide vanes of the VDL series ceiling swirl diffusers can be adjusted. The ability to change the direction of air flow ensures operation in heating and cooling modes or when changing the air flow range. Horizontal air supply is carried out in all directions. Vertical air supply is possible in heating mode. The temperature difference between the supply air and the room can range from –12 to +15 K.

The drive (optional) adjusts the position of the blades if necessary.
