By minimizing the surface pressure of the fan blade when
in contact with the air, the peak noise is reduced to a level
that is among the lowest in the world.

With a unique design that reduces the vibration of the
twin rotary compressor while simultaneously applying
double cam, the torque variation is reduced by 40%
compared to a single rotary compressor.

With strong torque and powerful Neodymium magnetism
inside the rotor, the BLDC motor provides large air volume
and high static pressure.
Precise speed control provides 13 different steps which
makes operation smoother. Both electrical and mechanical
noise is more silent, and high speed operation is available.
The balanced stability of a twin rotary compressor keeps
the vibration minimal.
