Plenum box Dimensions D lindab | we simplify construction MB L B H Description MB is a plenum box for supply and extract air, intended to achieve a stable airflow into diffusers, air flow measurement and balancing and also to attenuate sound from the duct system. MB is available with several damper options and has small overall dimensions to ease up installation and handling. Damper type B is an unique linear cone damper which 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 B is available for both supply and extract and has a readable K-value scale and can therefore be pread-just- ed before the final balancing. Also available as VAV damper in plenum box type MBV. Damper type C and E are with rotating blade dampers for respectively supply and extract. Typically used in appli- ca-tions that don’t require a high balancing pressure in the plenum box. If the MB box is used without damper for supply air, it is nec- essary to install distribution filter PP. This distribution fil-ter is standard in the MBC box. • Small dimensions and simplified installation. • High capacity and low sound. • Several damper options for all applications. • Prepared for future system changes.
