SXDE7025HB evidence reconciliation for compact EC cooling
Engineering summary: The photographed label identifies SXDE7025HB at AC 115/230V, 50/60Hz and 4W. The controlled 70x70x25mm catalog provides the H, M and L performance grades. This page publishes the H-grade values while keeping the exact bearing, wiring and installed operating point tied to the approved quotation and sample.
| Exact photographed model | SXDE7025HB |
|---|---|
| Fan size | 70 x 70 x 25 mm EC axial fan |
| Product-label input | AC 115/230V, 50/60Hz |
| Product-label power | 4W |
| 7025 catalog working range | 100-264VAC; final wiring and input behavior must follow the approved model drawing |
| Catalog high-speed H grade | 0.05A, 4.0W, 3500 RPM, 27.6 CFM, 3.8 mmH2O, 33 dBA |
| Catalog-family weight | 70 g |
| Frame and impeller material | Plastic (UL94V-0) |
| Lead wire | UL type; conductor assignment, length, connector and termination require the approved wiring specification |
| Operating environment | -10°C to 70°C and 35% to 85% RH |
| Storage environment | -40°C to 80°C and 35% to 85% RH |
| Bearing evidence boundary | The exact HB SKU media identifies a dual-ball-bearing configuration, while the 7025 catalog lists sleeve and ball bearing as family options. The quotation and approved sample must bind the final bearing code. |
| Performance evidence boundary | Catalog values are typical at nominal voltage. Noise is measured one meter from the fan intake. Confirm the operating point against the equipment resistance curve and approved sample. |
| OEM release evidence | Approved SXDE7025HB drawing, controlled datasheet, wiring diagram, label revision, connector, tolerance, bearing code and representative equipment validation |
| Manufacturer and quality review | SENSDA ELECTRONICS LIMITED / SXDOOL. Source Factory Direct project review, ISO 9001:2015 quality-management documentation, Dynamic Balancing, OEM/ODM Customization and 100% End-of-Line Testing can be reviewed against the approved production control plan. |
70x70x25mm EC fan catalog grades
| Grade | Catalog model | Current | Power | Speed | Airflow | Static pressure | Noise |
|---|---|---|---|---|---|---|---|
| High-speed H grade | SXDE7025HX | 0.05A | 4.0W | 3500 RPM | 27.6 CFM | 3.8 mmH2O | 33 dBA |
| Medium-speed M grade | SXDE7025MX | 0.04A | 3.0W | 3000 RPM | 23.7 CFM | 3.1 mmH2O | 28 dBA |
| Low-speed L grade | SXDE7025LX | 0.03A | 2.0W | 2500 RPM | 19.7 CFM | 1.9 mmH2O | 24 dBA |
Release boundary: The H, M and L values are catalog-grade references, not a substitute for a signed model drawing. The removed 3300 RPM / 67 g graphic conflicts with the controlled catalog and is not used as release evidence. Confirm voltage, bearing code, wire definition, connector, airflow curve and acceptance test before production.
SXDE7025HB engineering FAQ
Can 27.6 CFM be used as the installed airflow of SXDE7025HB?
No. The 27.6 CFM catalog value is a typical free-air value for the high-speed 7025 grade at nominal voltage. Installed airflow is the intersection of the fan curve and the equipment resistance curve. Use the 3.8 mmH2O maximum-pressure reference and validate the selected operating point in the actual enclosure.
Does the 115/230V label mean the fan can be wired in any AC system without review?
No. The label identifies the input class and the 7025 catalog lists a 100-264VAC working range, but the final wiring method, grounding, conductor colors, connector, protection and regional supply conditions must follow the approved SXDE7025HB wiring specification.
Why does the controlled catalog speed differ from the 3300 RPM shown in an older SXDE7025HB graphic?
The controlled 70x70x25mm catalog lists the high-speed H grade at 3500 RPM, 4.0W and 27.6 CFM. The older 3300 RPM graphic conflicts with that source and has been removed from the product gallery. Production release should use the current approved datasheet and sample label revision.
How should a buyer specify the SXDE7025HB bearing before sample qualification and production release?
The exact HB product media identifies a dual-ball-bearing configuration, while the catalog also shows that the 7025 family can be supplied with sleeve or ball bearing options. State the required bearing code, expected duty, orientation, temperature profile and acceptance evidence on the RFQ so the quotation and sample cannot be substituted with a different family option.
Continue with the fan selector, review the EC fan family, review the control-cabinet application guide, or submit a model-specific RFQ.
