Ultra-quiet 19 dB Operation Our indoor units are some of the quietest in the industry, operating at a noise level of as low as 19 dB. To put that into perspective, consider that background noise in a library is 30dB. Innovations like the multi-angled heat exchanger, modified fin shape and large-diameter fan have increased efficiency while allowing greater airflow volume to be pushed through at lower speeds. The introduction of an uneven fan-blade pitch and a remote-controlled vane add further significant reductions to air resistance as well.

The FD Series is designed for optimum cooling/heating performance as well as operational comfort. Quiet, energy-saving operation is supported by some of Mitsubishi Electric's latest technologies. Advanced functions such as i-see Sensor temperature control and the Plasma Duo air filtering and purification system raise room comfort levels to new heights.
