High efficiency & Low noise Axial Fan
YWF series are external rotor axial flow fans
Rated voltage is 220-240V,50/60Hz or 380-400V,50/60Hz.
Usually used in exhaust ventilation, equipment heat dissipation, refrigeration equipment, air conditioning and heating and ventilation industries.
Large air volume and low wind, suitable for projects with small system resistance.
Axial fan voltage has a single-phase 220V,three-phase 380V.
There are two kinds of direction of the wind: blowing, from the direction of the wind blade; Suction air, air from the direction of the net cover.
Outgoing mode can be with terminal junction box or output lead.
Product Details
Domi Refrigeration supplies High efficiency & Low noise fan blade for OEM buyers who need a drawing-driven component, stable repeat production, and a supplier that can discuss size, material, testing, and packaging before release.
For fan projects, diameter, pitch, hub shape, rotation direction, and balance target should be checked before sample approval.
Where this product fits
This product is used wherever the cabinet needs controlled airflow, quieter operation, and repeatable fan performance.
- freezer fan assemblies
- cabinet ventilation
- replacement airflow components
Materials and build options
Fan blades are usually specified by material choice, blade profile, hub shape, and balance target. The correct material depends on speed range, noise target, and whether the blade will run in a humid cabinet.
Diameter, pitch, hub opening, blade depth, and rotation direction must all be confirmed from the drawing or sample. Blade balance matters as much as outer size.
Specification guidance
| Item | Guidance |
|---|---|
| Main materials | Blade material and hub structure selected to support airflow, noise target, and balance. |
| Dimensions | Confirm diameter, pitch, hub opening, blade depth, and rotation direction from the sample. |
| Refrigerant / medium | This is not a pressure-bearing refrigerant component. Confirm the cabinet environment, airflow path, and moisture exposure instead. |
| Pressure / electrical note | Not applicable as a pressure-bearing part; balance, speed, and running environment are the key control points. |
| Testing | Testing should cover appearance, balance, rotation, and noise performance where the project requires it. Packaging should prevent blade deformation in transit. |
| MOQ | MOQ depends on the blade size and finish. Small sample checks can be discussed before a larger commitment. |
| Lead time | Lead time depends on mold or tooling status, quantity, and the level of balance confirmation required. |

Testing and release checks
Testing should cover appearance, balance, rotation, and noise performance where the project requires it. Packaging should prevent blade deformation in transit.
If the blade is a replacement part, the old sample should be kept as the reference for the next production run.
FAQ
Can you confirm the size from a sample or photo?
Yes. A blade sample or a measured sketch is enough to begin the size confirmation process.
How do you confirm refrigerant, pressure, or operating conditions?
For blades, the useful checks are material, diameter, pitch, rotation, and noise target rather than refrigerant.
What is needed for MOQ and lead time confirmation?
Quantity, sample condition, and tooling status are the main MOQ and timing inputs.
