PKA 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 PKA 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 A x A PKA Ød A U * Free area A m mm mm mm m 2 2 kg 1 1 2 2 5 5 2 2 3 3 5 5 2 2 0 0 0 0 0 0 . , 0 0 1 1 8 8 0 0 . , 9 9 1 1 6 6 0 0 2 2 9 9 5 5 2 2 6 6 0 0 0 0 . , 0 0 2 2 3 3 1 1 . , 4 4 2 2 0 0 0 0 3 3 9 9 5 5 3 3 6 6 0 0 0 0 . , 0 0 3 3 2 2 . , 2 2 2 2 5 5 0 0 4 4 9 9 5 5 4 4 6 6 0 0 0 0 . , 0 0 4 4 3 3 3 3 . , 0 0 3 3 1 1 5 5 5 5 9 9 5 5 5 5 6 6 0 0 0 0 . , 0 0 5 5 7 7 4 4 . , 3 3 4 4 0 0 0 0 5 5 9 9 5 5 5 5 6 6 0 0 0 0 . , 0 0 7 7 5 5 4 4 . , 4 4 * U x U = Ceiling grid opening.
