PCV/LCV is a circular PCA/LCA type diffuser with integral motor intended for supply air of varying volume flow (VAV). The integral motorized damper ensures a constant throw so the Coanda effect always is maintained. The damper setting can be controlled by a room regulator, BMS or other 0-10 V control signal.

  • Can vary the volume flow between 0-100 %
  • Preset min. and max. volume flow *)
  • Settings can be changed with Belimo PC-tool
  • VAV zone pressure must be controlled (see pages 518-525)
  • The diffuser should be installed together with an MBAV type plenum box
  • For exhaust PCA / LCA should be used (see pages 69/93)

*) Settings are made from a pre-defined, accessible constant pressure in the air duct immediately before the diffuser. The diffuser is typically used at a constant pressure of 30-50 Pa.
