What Is the WEIGUANG YWF4D-350S Rotor Axial Fan 380V?

The WEIGUANG YWF4D-350S Rotor Axial Fan 380V is a precision-engineered industrial DC axial fan designed for forced-air cooling in industrial automation systems. With its robust bearing system and optimized blade geometry, it delivers high static pressure and low-noise operation — a combination that makes it well-suited for both factory-floor equipment and laboratory instrumentation. It is manufactured by Weiguang and distributed worldwide through KOEED.

In short: The WEIGUANG YWF4D-350S Rotor Axial Fan 380V is a 380V industrial industrial cooling fan that delivers reliable forced-air thermal management for electronic enclosures, automation cabinets, and power conversion equipment — engineered for continuous-duty operation with long service life.

Key Features and What They Mean for Your Equipment

1. High-Temperature Rated Materials

What it means: The fan frame, impeller, and internal insulation are manufactured from materials rated for sustained exposure to elevated ambient temperatures.
Why it matters: Standard plastic fans can soften or deform above 70°C; this fan uses grades that maintain structural integrity well beyond that threshold.
Result: Suitable for deployment inside industrial ovens, foundry control panels, and outdoor enclosures in hot climates without premature degradation.

2. Low Power Consumption

What it means: The 380V motor is wound for efficiency, drawing minimal current while delivering its rated airflow.
Why it matters: In large installations with dozens or hundreds of fans, a small per-unit efficiency gain compounds into significant energy savings.
Result: Reduced electrical operating cost and lower heat contribution from the fan motor itself — a virtuous cycle for enclosure cooling.

3. Finger Guard Compatible Mounting

What it means: The frame includes integrated mounting holes on standard spacings that accept industry-standard finger guards and filter assemblies.
Why it matters: Safety regulations in many jurisdictions require finger guards on accessible fans in equipment; pre-drilled holes eliminate adapter plates.
Result: Faster assembly and compliance with OSHA / EU Machinery Directive guarding requirements without custom fabrication.

Key Specifications

Note: Always verify specifications from the product label or manufacturer datasheet before placing an order.

Typical Applications

• Industrial Oven and Furnace Control: Cooling electronic controllers and HMI panels mounted on or near high-temperature process equipment in heat-treatment facilities.
• Food & Beverage Processing Lines: Washdown-area panel cooling for PLCs and VFDs controlling conveyor, filling, and packaging machinery in food-grade production environments.
• Water / Wastewater Treatment: Enclosure ventilation for SCADA RTUs, pump controllers, and chlorine analyzer electronics in treatment plant buildings.
• Oil & Gas Field Automation: Remote terminal unit (RTU) and flow computer cooling in wellhead enclosures exposed to high ambient temperatures in desert operations.
• Railway Signaling Bungalows: Ventilation fans for trackside equipment cases housing interlocking controllers, axle counter evaluators, and level-crossing predictors.
• Semiconductor Fab Sub-Fab: Cooling vacuum pump controllers, abatement system monitors, and gas panel electronics in the sub-fabrication support level of wafer fabs.

Frequently Asked Questions

"What do the different numbers in the model code mean?"

Each manufacturer uses a proprietary numbering system. Generally, the model code encodes frame size (e.g., 120 = 120mm), voltage (12 = 12V, 24 = 24V), bearing type, speed grade, and special features like PWM or tachometer output. We recommend checking the manufacturer datasheet for a full decoding table. If you cannot find the datasheet, KOEED can help cross-reference the model number — contact us with your full part number.

"Can you supply a compatible fan guard or filter for this model?"

Standard metal wire finger guards and foam dust filters are available for most fan frame sizes. The common sizes — 40mm, 60mm, 80mm, 92mm, 120mm, 140mm, 172mm — all have industry-standard mounting hole patterns. KOEED can include matching guards and filters as part of your order. Specify your needs when you send your BOM or inquiry to Moritta@KOEED.COM.

"What if the fan is too loud for my application?"

Fan noise is primarily a function of RPM and blade design. If the noise level is too high, consider: (1) using a PWM controller to run the fan at a lower speed when maximum airflow is not needed, (2) selecting a lower-RPM variant of the same frame size, or (3) increasing the frame size (e.g., 120mm instead of 80mm) to move the same airflow at lower RPM and lower noise. We stock fans across the full speed spectrum — tell us your airflow and noise requirements and we will recommend the best match.

Why Source Cooling Fans Through KOEED?

Cooling fans are consumable components — they wear out, and when they do, your equipment is at risk of thermal shutdown. KOEED maintains stock of industrial cooling fans across multiple brands, frame sizes, and voltage ratings. If the exact model you need is not listed on our site, we can source it from our global supplier network. We support single-unit replacements and bulk BOM orders alike.

• Multi-brand inventory: SANYO Denki, Nidec, NMB, Delta, Sunon, and more — one purchase order covers all your fan requirements.
• Hard-to-find models: Discontinued series, odd frame sizes, special voltage variants — we locate what others cannot.
• BOM consolidated quoting: Send your complete fan list and receive a single quotation with availability and lead time for every line item.
