If you are looking for a high-efficiency and energy-saving ventilation solution, then EC backward centrifugal fan is your best choice. EC backward centrifugal fan is a centrifugal fan that uses electronic commutation three-phase AC permanent magnet synchronous external rotor motor, which has the following advantages:
- High energy efficiency: Compared with conventional AC fans, EC fans can reduce energy consumption by 30%-60%.
- Wide voltage range input: single-phase 200-230V, three-phase 380-480V, 50/60Hz universal, and the fan speed does not depend on the frequency of the grid.
- Wide stepless speed regulation range: stepless speed regulation function can be realized by 0-10V.DC/PWM, current control, integrated PID regulation and other methods, and high motor efficiency can still be guaranteed at ultra-low speed operation.
- Intelligent and controllable: The fan can be set and adjusted for the highest and lowest speed, maximum power, maximum current, resonance point avoidance and other parameters through data interaction between the computer and the fan. The fan can also be adjusted and controlled according to the changes of temperature, humidity, wind pressure and other parameters of the working environment.
- Small and compact: The external rotor structure + embedded controller design makes the fan structure more compact.
- Multiple protection functions: soft start, adjustable acceleration, stepless speed regulation. Protection functions: under-voltage, over-voltage, over-current, over-temperature, phase loss, stall and other protection functions to ensure safe and reliable operation of the fan.
- Various impeller materials: plastic + glass fiber, galvanized sheet or aluminum alloy and other impeller materials can be selected according to different application occasions to adapt to different temperature and environmental requirements.
- Various sizes and specifications: various industry standard universal sizes such as 133mm-630mm can be provided to meet different air volume and wind pressure requirements.
EC backward centrifugal fan is widely used in refrigeration technology, building ventilation, energy and environment, mechanical and industrial production process, clean room technology and medical technology, mobile applications and vehicles, IT and telecommunications, food chain and other fields.
