High-Efficiency EC Axial Fan for Heat Pump Systems
As the global demand for low-carbon, energy-efficient heat pump systems continues to surge, every component inside the unit faces growing scrutiny—from the compressor to the fan. Among these, the axial fan plays a pivotal role in defining system efficiency (COP), noise level, and user experience.
AFL Motor has developed a purpose-built, high-performance EC axial fan specifically for integrated heat pumps:
Model Series: A3P500-EC102-*
This smart, quiet, and energy-optimized fan solution helps heat pump manufacturers elevate their product energy ratings, meet stringent ERP & Ecodesign regulations, and improve end-user satisfaction.
Key Features of AFL EC Axial Fan for Heat Pumps
✅ Whisper-Quiet Operation
Advanced low-noise blade geometry and flow-optimized impeller design ensure silent airflow—even during peak performance—making it ideal for residential or commercial indoor installations.
✅ Stable, Consistent Airflow
Designed for low-static-pressure environments in external units, this fan delivers steady airflow to keep the COP stable across different ambient temperatures.
✅ High-Efficiency EC Motor
The core EC motor achieves IE4+ level efficiency, reducing power consumption while offering soft start, overload protection, and superior lifespan.
✅ Smart Control Compatibility
Integrated support for 0–10 V, PWM, and RS485/Modbus allows seamless communication with your BMS or inverter system. Enables variable-speed operation, remote diagnostics, and real-time load matching.
Designed for Heat Pump Integration
This fan was purpose-built for HVAC R&D teams designing air-to-water, split-type, and all-in-one heat pumps. Its compact form factor, intelligent electronics, and thermal stability make it easy to integrate.
