Description
Swirl diffusers for installation in stages in air conditioning systems create swirling supply air for supply to rooms. 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. Swirl diffusers for installation in stages supply air directly to the work area, as well as individually to the persons located in this area. The result is ventilation mixing in comfort zones and excellent air quality in the work area.
Swirl diffusers for installation in stages of the SDRF series have fixed guide vanes. Air supply parallel to the mounting surface. The temperature difference between the supply air and the room can range from –6 to +6 K.
Standard sizes 1, 2, 3, 4, 5, 6 air distribution holes
Min. air flow level 2 – 12 l/s or 7 – 43 m³/h
Max. air flow level 5 – 25 l/s or 18 – 90 m³/h
Temperature difference between supply air and room –6 to +6 K
