Multi-cone diffuser lindab | we simplify construction Dimensions Vertical Ød Aluminium Galvanized FKD Max. 15 mm H 8 ØU ØD Description FKD is an adjustable circular multi-cone diffuser, which is typically used for supply air. The diffuser can be switched between horizontal and vertical supply air and is therefore ideal for the supply of both heated and cooled air. Installing an FKD diffuser up to size 400 in a plenum box type MB can help to achieve a stable airflow 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 genera- tion. Furthermore the construction of the damper gives an accurate and reliable measurement. Damper type C has a rotating blade damper for supply air. Typically used in appli- cations that don’t require a high balancing pressure in the plenum box. • Suitable for supply air • Vertical or horizontal supply air pattern • Plenum box with several damper options Maintenance The multi-cone insert can be removed to enable cleaning of internal parts or to gain access to the duct or box. The visi- ble parts of the diffuser can be wiped with a damp cloth.
