EC (Electronically Commutated) Backward Centrifugal Fans represent the latest advancement in air moving technology. They integrate EC motors with backward-curved impellers to deliver superior performance, energy efficiency, and controllability.

1.Product Features:

  • EC Motor Technology:

Utilizes brushless DC motors with integrated electronics for precise speed control and efficient operation.

  • Backward-Curved Impellers:

Optimize airflow and pressure generation while minimizing noise and energy consumption.

  • Variable Speed Operation:

Allows for seamless adjustment of fan speed to meet varying airflow requirements, resulting in energy savings and enhanced comfort.

  • Integrated Control Options:

Compatible with various control methods, including PWM (Pulse Width Modulation), 0-10V analog signal, and Modbus communication protocols.

  • Low Maintenance:

Maintenance-free operation with long service life due to the absence of brushes in the motor design.

2.Application Scenarios:

  • HVAC Systems:

Ideal for use in heating, ventilation, and air conditioning systems in commercial buildings, offices, hospitals, and hotels.

  • Data Centers:

Critical for cooling and ventilation in data centers to maintain optimal operating temperatures and airflow for sensitive equipment.

  • Indoor Air Quality (IAQ) Solutions:

Suitable for air filtration, ventilation, and exhaust systems in cleanrooms, laboratories, and manufacturing facilities.

  • Energy Recovery Ventilation (ERV):

Used in ERV systems to recover heat or coolth from exhaust air and transfer it to incoming fresh air, improving energy efficiency and indoor air quality.
