PKAL can be used for both supply and extract air. PKAL is suitable for horizontal supply of cooled air and can be equipped with accessories of various types in order to achieve optimal function. Installing a PKAL 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 plenum box. • Suitable for both supply and extract air • Suitable for horizontal supply of cooled air • Option of 1, 2 and 3-way supply air • Plenum box with several damper options Maintenance The face plate can be removed to enable cleaning of internal parts or to gain access to the duct or box. The visible parts of the diffuser can be wiped with a damp cloth. Order code Product Type PKA L Connection dim.
