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.

Heat pump products have been receiving a considerable amount of attention recently for their
energy-saving effects. In fact, inverter heat pump products have signicantly higher energy
efciency than constant-speed, non-inverter units. As a result, LG Inverter products can help
you save up to 74% more energy when heating. Use of an energy efcient inverter system can
also help decrease your carbon footprint by reducing overall energy consumption.

The LG air conditioning units can auto-

LG’s new larger fans allow you to feel

you feel warm sooner.
