Backward curved impeller
Performance introduction
The fan consists of outer rotor asynchronous motor, aluminum impeller or iron impeller or
plastic impeller.The motor has unique feature of low temperature rise of the motor, which can
prolong the life and reliability. The fan has the backward curved impeller. Also, the fan has the
characteristic of a big configuration, low vibration, low noise and easy to installation. With the
above feature, it can work with some refrigeration equipment to clean the staging, apartment,
airconduit, to purify the ventilate, to protect the environment and to control the pollution.
