Swirl diffuser

RC14 is a circular diffuser with integrated swirl insert with fixed bars. The diffuser is suitable for the horizontal supply of very cold air. The integrated swirl insert ensures optimum distribution and high induction.
Installing a RC14 diffuser in a plenum box type MB can help to achieve a stable flow of air to the diffuser as well as real-ise 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 is with a rotating blade damper for supply air. Typically used in applications that don’t require a high balancing pressure in the plenum box.
