Centrifugal Fan
BC310 Series
Applications
The core advantages of EC 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.

EC Backward Curved Centrifugal Fan,100-3500 m³/h,Impeller size： 133-355mm，What industry and specific equipment is this type of fan mainly used for?
EC backward-curved centrifugal fans in the 133-355mm (100-3500 m³/h) range are the high-efficiency workhorses for systems demanding high static pressure, space-saving footprints, and precise airflow control.
These fans typically utilize an external rotor motor design, where the electronically commutated (EC) motor is nested directly inside the impeller hub. This eliminates the need for an external motor shaft and drive belt, drastically reducing the physical footprint. Their backward-curved blades have a "non-overloading" power characteristic, meaning the motor will not burn out even if the system pressure drops suddenly.
Because of their ability to push air through high-resistance pathways while maintaining energy efficiency, they are primarily integrated into the following industrial and commercial equipment:
| Industry | Specific Equipment | Core Function & Advantage |
|---|---|---|
| HVAC & Air Purification | Heat Recovery Ventilation (HRV), Air Handling Units (AHU), Commercial Purifiers | Pushes high volumes of air through dense HEPA filters and complex ductwork. The backward-curved design prevents stalling under high filter resistance. |
| Smart Agriculture & CEA | Containerized Plant Factories, Greenhouse Climate Control | Overcomes the high static pressure created by dense, multi-tier plant canopies (such as high-density tomato or strawberry racks). The EC motors easily integrate with Modbus/MQTT sensor networks for automated, recipe-driven climate control. |
| Precision Cooling & IT | Data Center CRAC units, Telecom Cabinets, Server Rack Exhausts | Provides continuous, high-reliability cooling. The EC motor's stepless speed control responds dynamically to thermal loads, saving significant energy during off-peak hours. |
| Cleanroom Technology | Fan Filter Units (FFU), Biological Safety Cabinets, Clean Benches | Delivers stable, uniform laminar airflow across strict filtration barriers while adhering to stringent European and international energy efficiency directives. |
| Industrial Automation | Inverter Cabinets, CNC Machine Cooling, High-Power UPS Systems | Efficiently extracts waste heat from densely packed electrical enclosures where the compact outer-rotor profile maximizes available cabinet space. |
The 100 to 3500 m³/h airflow range perfectly covers the transition from high-end residential systems (like whole-house ventilation) up to medium-scale industrial machinery, making this specific size bracket one of the most widely specified components in modern air handling.
