Delta Electronics / Fans High-Efficiency Non-Frost DC Refrigerator Fans

Delta Electronics / Fans High-Efficiency Non-Frost DC Refrigerator Fans feature a dedicated bearing system that will not freeze in temperatures below -40°C. A novel blade design provides sufficient airflow with lower noise in the system tunnel and keeps the uniform temperature inside the refrigerator. With advanced motor driver circuit technology, these fans can achieve high efficiency and low vibration at the same time. Delta Electronics / Fans High-Efficiency Non-Frost DC Refrigerator Fans also feature a PWM function for wide speed range adjustment.
