Product Introduction
The EC motor used in EC ahu centrifugal fan adopts a high-efficiency permanent magnet design. Compared with traditional AC motors, permanent magnet motors provide smoother magnetic field synchronization and faster response speeds. Speed adjustment can be completed within milliseconds, allowing the fan to quickly respond to changing ventilation demands.
Motor efficiency can exceed 90%, significantly improving electrical energy conversion efficiency and reducing energy waste. Because less energy is lost as heat, the motor generates less thermal buildup and typically does not require additional cooling systems.
Permanent magnet motors are also smaller and lighter, which helps reduce the overall size and weight of the fan, making installation easier in compact spaces while lowering transportation and installation costs.

To meet the cooling needs of compact equipment and installations with limited space, the EC ahu centrifugal fan series has been developed. The nominal diameters range from 133 mm to 225 mm, featuring a compact structure that can be easily embedded inside electronic cabinets or small instruments.
The impeller is made from PA66 reinforced plastic with 30% glass fiber (PA66+GF30%), providing lightweight construction and low rotational inertia. Combined with compact EC motors, the input power ranges from 30W to 500W, resulting in extremely low energy consumption.
Despite its small size, the fan offers excellent heat dissipation performance, quickly removing heat generated by internal electronic components and preventing overheating damage.
The fan supports two installation options: bracket-free installation or customized sheet-metal mounting brackets. Brackets can be made from galvanized steel, cold-rolled steel, or aluminum, with optional electrophoretic coating for enhanced corrosion resistance.
The mini series has passed CCC and CE certifications and is widely used in rail transit equipment, small instruments, and residential fresh-air ventilation systems.

FAQ
1. What control methods are supported by EC fans?
EC fans typically support analog control such as 0–10V signals. Some models may also support PWM or digital interfaces. These control options allow precise speed regulation. Compatibility depends on the specific fan model and controller configuration.
2. Can EC centrifugal fans operate at low speed continuously?
Yes, EC centrifugal fans can operate at low speed for extended periods. Efficiency remains high even at reduced speed. The motor controller manages torque and temperature automatically. This makes EC fans suitable for continuous low-load operation.
3. How does EC technology align with future regulatory trends?
EC technology aligns well with trends toward higher efficiency standards. Demand-controlled operation supports regulatory direction. Reduced energy consumption supports future compliance. EC fans are considered a future-proof 4. Are EC fans suitable for cross-border engineering projects?
EC fans are commonly used in cross-border engineering projects. Flexible configuration supports different regional requirements. Proper coordination ensures compliance. They are suitable for international system integration.
5. Is customization available for specific project requirements?
Customization may be available for voltage, control, or mounting options. Project-specific requirements can often be accommodated. Custom solutions help meet unique system needs. Details should be discussed before production.
6. How does EC technology support sustainability goals?
EC technology reduces energy consumption and operational waste. High efficiency contributes to lower carbon emissions. Demand-based control avoids unnecessary power usage. This supports sustainability and energy-saving initiatives.
