Tips: What is a double inlet centrifugal fan?

A double inlet centrifugal fan is a type of fan that uses two inlets to draw air into the fan casing. This design improves airflow efficiency and increases the fan's capacity compared to single inlet models. In a double inlet centrifugal fan, air enters the fan from both sides of the impeller, which is located centrally within the casing. As the impeller spins, it accelerates the air outward and directs it through a volute or diffuser, which converts the kinetic energy into static pressure and directs the airflow out of the fan outlet. This configuration provides higher airflow rates and more balanced air distribution, making it suitable for applications requiring substantial air movement, such as in HVAC systems, industrial ventilation, and large-scale cooling systems. The double inlet design helps reduce noise and improve overall performance in demanding environments.

Existing reviews of EC Double Inlet Centrifugal Fan, 146mm, 230V

High-quality and low-noise fan

I’ve been using this 146mm EC double inlet centrifugal fan for an HVAC project, and it has performed exceptionally well. The airflow is steady and strong thanks to the 115W EC motor, and the fan runs much quieter than I expected—even at around 2000 rpm. Installation was simple, and it works flawlessly on both 50Hz and 60Hz mains voltage. What really stands out is the energy efficiency; the EC motor keeps power consumption low while still delivering reliable performance. After continuous operation in a ventilation setup, the fan has stayed stable with no vibration or overheating. Overall, it’s a high-quality, low-noise fan that’s perfect for HVAC systems and other applications needing consistent, efficient airflow.
