Delefun DFB12032 DC centrifugal fan: high-efficiency ventilation solution

The DFB12032 is a compact DC centrifugal fan designed for targeted airflow where duct resistance is present. With a flange mount for easier installation and a side outlet airflow path, it’s a practical choice for equipment ventilation and cooling projects.

DFB12032 size (120×120×32mm) with flange mount and side outlet.

Core performance of DFB12032 DC centrifugal fan

This model uses a centrifugal impeller design with axial air intake and radial air exhaust, helping generate focused airflow to overcome moderate resistance. In typical configurations, it is described as a 12V DC centrifugal fan 41.2 CFM 35mmAq that balances airflow and static pressure for ventilation tasks.
