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.
