Swirl diffuser

RC15 is a circular swirl diffuser with adjustable bars. The diffuser can be used for both supply and extract air. The swirl pattern ensures high induction and a large dynamic range, and is therefore ideal for the horizontal supply of very cold air.
The diffuser can also be set to a vertical supply air pattern, enabling supply of heated air.
Installing a RC15 diffuser in a plenum box type MB can help to achieve a stable flow of air to the diffuser as well as realise the potential for individual adjustment.
Damper type B is an unique linear cone damper which allows to use the full operational area (0-100%) and allows to balance with a high pressure drop over the box with low sound generation. Furthermore the construction of the damper gives an accurate and reliable measurement.
Damper type C and E are with rotating blade dampers for respectively supply and extract. Typically used in applications that don’t require a high balancing pressure in the plenum box
