BB SERIES
Ceiling swirl diffusers in round and square shapes for high air flow rates. The position of the guide vanes of the BB series ceiling swirl diffusers can be adjusted. The direction of air flow can be changed if necessary. Horizontal air supply in one direction, in two or all directions. Vertical air supply is only possible for heating. The temperature difference between the supply air and the room can range from –12 to +10 K.
- Standard sizes 300, 400, 500, 600, 625, 825
- Air flow range 7 – 470 l/s or 25 – 1692 m³/h
- Front panel made of galvanized sheet steel with powder coating
- For supply and extract air (for systems with variable and constant air flow)
- Suitable for all types of ceilings, also suitable for free hanging when fitted with an edge panel
- Rapid equalization of temperatures and reduction of air flow speed is achieved due to the high level of ejection
- Diffusers can provide 35-fold air exchange when arranged in a row with a minimum pitch of 0.9 m (from center to center)
- Ideal for comfort zones
Additional equipment and accessories
- Diffuser front panel can be painted in RAL CLASSIC colors, guide vanes in white or black
- Horizontal or vertical duct connection
- Plenum box with measuring point and valve flap with flexible rod
To create an attractive, holistic room design, diffusers from the BB series can also be used for exhaust ventilation. For exhaust systems, guide vanes are not required. The metering point and damper blade with flexible rod (optional) allow you to adjust the air flow when the front panel is installed. Flap blade (optional) to balance air flow simplifies operation.
- 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.
