Applications
The core advantages of EC/DC/AC backward-curved centrifugal fans are: high static pressure, high airflow, adjustable speed, energy efficiency, low noise, and suitability for continuous operation. Therefore, they are mainly used in HVAC and industrial ventilation scenarios that require ducted air supply, variable air volume control, and overcoming relatively high system resistance.
