EC Centrifugal Fans

Smarter Cooling, Sustainable Future
As worldwide green policies become more stringent, there is an increasing demand for improved power efficiency in ventilation and air conditioning systems. The most recent generation of ventilation solutions employs advanced frequency conversion techniques and aerodynamic design to reduce power consumption, enabling green transformation.

Green EC Centrifugal Fans For high-efficiency HVAC systems
The latest generation of SUNON Green EC fans has enhanced fan structure and noise cancellation to increase overall fan performance. Smart control in fans allows for remote control of commercial high-efficiency HVAC systems , automated airflow modification, and accurate speed change.

2 versions of Green EC Centrifugal Fans
SUNON offers two types of Green EC centrifugal fans: motorized impeller with a support bracket (CBA series) and without a support bracket (CBI series) to suit clients' ventilation systems.



✔️Smart Speed Control
Built-in 0-10 VDC, PWM control; supports RS485 MODBUS protocol to precisely control airflow.

️✔️Protected against the elements
Fans are rated against IP44-IP55 dust, water, and even explosions.

️✔️️Customizable for your system
Green EC fans can be customized to meet your unique HVAC needs. For example, you can adjust the fan speed, size, voltage, connector, protection level and other requirements according to your HVAC system.



Smart Control, High Performance Thermal and Ventilation Solutions Large-size Green Centrifugal Fan Series, featuring high airflow, silence, and smart controls, are suitable for applications such as HVAC&R, industrial, renewable energy, and data centers where ventilation requires 100-480 voltage designs and smart speed controls, as well as ErP 2026 for clients who prioritize power-saving and sustainability in their systems.
