Do you want to save electricity, reduce carbon emissions and improve ventilation effect? If so, you must know our company’s EC backward centrifugal fan, which is a high-efficiency and energy-saving ventilation equipment that uses EC brushless external rotor motor and backward inclined impeller. It has the following features:
-
EC motor technology: EC stands for “electronic commutation”, which means that the current is transferred from one branch to another in a clear way in power electronics. This can avoid the friction and sparks caused by brushes and commutators in traditional AC motors, thus reducing energy loss and noise and extending motor life.
-
Energy saving and environmental protection: EC motor can achieve more than 70% of power efficiency in ventilation systems, saving more than 50% of energy than traditional AC motors. This means that you can get more air volume and air pressure with less power, thus saving your electricity bills and reducing carbon emissions.
-
Intelligent and controllable: EC motor can also achieve precise control, stepless speed regulation and duty cycle output speed regulation. Some models have RS485 network communication protocol function, which can realize group control of fans. This allows you to flexibly adjust the operating state of the fan according to your actual needs, optimize ventilation effect and energy consumption.
-
Backward inclined impeller: The flow channel of the backward inclined impeller is relatively narrow and long, and the change of the cross section of the flow is gentle. The fluid can get better guidance in the backward inclined blade. The flow velocity is low, the energy loss is small, so the noise is low. The backward inclined impeller can also effectively prevent dust accumulation on the blade, maintain the cleanliness and performance of the fan.
EC backward centrifugal fan is widely used in data centers, precision air conditioning, FFU/EFU, air purifiers/fresh air units, rail transit, refrigeration equipment, medical industry, charging piles and other fields. It provides you with comfortable, healthy and safe ventilation environment, saves your electricity and maintenance costs, improves your work efficiency and quality of life.
