China Factory 4-72C Industrial Centrifugal Fan - High-Quality Suppliers with Customizable Outlet Positions

The fan series is available in models ranging from 2.8C to 12C. Airflow (traffic) ranges from as low as 1,131 m³/h for the smallest model (2.8C) up to 75,552 m³/h for the largest model (12C), covering a wide spectrum of industrial ventilation requirements.

All models across the entire parameter range support dual voltage operation at 220V and 380V, with a standard operating frequency of 50 Hz. This makes them compatible with most international power supply standards.

Power options range from 0.75 kW for smaller models such as the 3.2C at lower speeds, up to 75 kW for the 12C model. Each model offers multiple power configurations to match different operational demands and energy efficiency requirements.

Higher fan speeds generally result in greater airflow (traffic) and total pressure output. For example, within the same model, a higher RPM setting delivers significantly more m³/h and Pa compared to lower speed configurations. Selecting the appropriate speed allows precise control over ventilation performance and energy consumption.

Total pressure across all models ranges from approximately 356 Pa (model 8C at low speed) up to 3,213 Pa (model 5.6C at high speed). Total pressure is a critical parameter for overcoming duct resistance and ensuring effective air distribution throughout a ventilation system. Higher pressure ratings are suited for longer or more complex duct layouts.

Selecting the correct model depends on your required airflow volume (m³/h), system static pressure (Pa), available power supply, and installation space. Match your required traffic and total pressure values against the parameter table above, then choose the model and speed combination that best fits your system design. For complex applications, consulting with a technical specialist is recommended.
