The AC External Rotor Axial Fan for Weiguang YWF4E-350S operates at 220V and 1400RPM, delivering consistent airflow for industrial ventilation and cooling systems. This fan features an external rotor design, which integrates the rotor directly into the impeller hub, reducing overall size while enhancing heat dissipation efficiency. The motor housing is constructed from heavy-duty aluminum alloy, providing robust protection against dust, moisture, and mechanical stress. Precision-balanced blades ensure smooth operation with minimal vibration, contributing to extended service life and quieter performance.

The unit is engineered with high-quality copper windings and sealed ball bearings, supporting continuous duty in demanding environments. The external rotor configuration allows for more compact mounting and improved air circulation, making it suitable for use in electronic enclosures, HVAC units, and machinery cooling. The fan’s IP54-rated enclosure guards against ingress from splashing water and solid particles, ensuring reliable operation even in workshop or outdoor settings. Rigorous quality control during assembly ensures consistent torque and airflow output across units.

At 1400RPM, this fan provides a balanced combination of static pressure and volumetric flow, effectively moving air through ducted systems or across heat sinks. The 220V AC input is compatible with standard industrial power supplies, simplifying installation. The fan includes pre-wired leads and a mounting flange for straightforward retrofitting onto existing equipment. Its robust build and efficient motor design contribute to low power consumption relative to airflow delivered, reducing operating costs over time.

Constructed with corrosion-resistant materials, the unit withstands exposure to oils, coolants, and humidity. The external rotor motor also aids in self-cooling, as airflow passes directly over the motor surface. This design reduces thermal stress on internal components, further improving reliability in long-run applications.

The fan’s compact footprint allows integration into space-constrained setups without sacrificing performance. This fan represents a cost-effective solution for replacing or upgrading existing units in the Weiguang YWF4E-350S series. Its combination of durable construction, efficient airflow, and straightforward installation offers practical value for industrial maintenance departments and equipment manufacturers seeking a dependable ventilation component.
