4-way ceiling cassette

Compact and ultra-quiet

They are ideal for installation in suspended ceilings thanks to their low installed height. Installation is also simplified by the lightweight design of the unit. The PLFY series is characterised by its whisper-quiet operation – only 27 dB(A) for models P32 to P50. A large-diameter turbofan ensures this low sound pressure level. Impellers with a low air resistance also play a key role in noise reduction. The special ventilation control, which immediately increases the speed steplessly when the thermostat is switched on or in dehumidification mode, avoids sudden noises.
