Excellent efficiency

Midea DC FCU adopt the brushless DC motor, the DC motor efficiency is up to 90%. The power consumption of

DC FCU can be reduced by more than 30% in contrast to the corresponding AC FCU.

DC brushless motor

The motor adopts fully enclosed structure design, it is energy-saving , of high operating efficiency and durable

motor. The motor bearing can operate 80,000 hours continuously, and easy for maintenance.

Low noise

Advanced 3-D spiral fan design reduces air resistance and operating sound. The motor bearing with unique

design makes less operation vibration.
