PCALPerforated diffuser

PCAL is a circular diffuser with perforated face plate and is adapted for lay-in T-bar ceiling 595 x 595. PCAL can be used for both supply and extract air. PCAL 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 PCAL 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 applications that don’t require a high balancing pressure in the plenum box.
