Quiet Operation
A factor contributing to HITACHI's development of the
quietest air conditioner yet, is the multi-blade centrifugal
fan used in these special two-way cassette type indoor
units.
Unlike conventional units, the noise level has been
reduced to an exceptionally low 30dB-A (1.0HP unit, Low
position). Ideal wherever quiet operation is important.
