The PRC/PRCI ceiling diffuser is best suitable for comfort ventilation. The small air slots arranged in a circular pattern ensure a proper air distribution, and keeps a horizontal airstream even with lower airflows. The unit consists of a front panel and a back box with a round air connection. Correctly dimensioned PRC/PRCI operates in a draught-free mode, at a low noise level. The diffuser can be connected directly to a TLM plenum box. Recommended max. ∆t: -10°C.
