lindab | we simplify construction Plain diffuser Dimensions Ø U Ød CRL C B Ø E Ø A Description CRL is a circular diffuser with an unperforated adjustable face plate and can be used for both supply and extract air. The diffuser can be switched between horizontal and verti- cal supply air, and is therefore suitable for the horizontal supply of cooled air or vertical supply of heated air. The CRL can be equipped with accessories of various types in order to achieve optimal function. Installing a CRL diffuser 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 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 applica- tions that don’t require a high balancing pressure in the ple- num box. • Suitable for both supply and extract air. • Suitable for horizontal or vertical supply air pat- terns. • Plenum box with several damper options.
