- Damage caused by improper installation, incorrect electrical connection, or operation outside the rated voltage, frequency, or temperature range
- Physical damage from accidents, mishandling, unauthorized modification, or tampering with safety devices
- Damage from exposure to corrosive chemicals, extreme humidity, or environments beyond the rated IP protection class
- Consumable components (filters, gaskets, cable glands) unless defective upon delivery
- Products operated beyond the rated duty cycle or without recommended maintenance intervals

- Acknowledgment: Our after-sales engineering team responds within 3 business days with a claim reference number and initial assessment
- Remote Diagnosis: Where possible, we attempt remote troubleshooting via email, video call, or Fan Selector diagnostic tools to resolve issues without product return
- Physical Inspection: If remote diagnosis is inconclusive, we issue a Return Authorization (RA) number. Ship the defective product to our Suzhou service center, freight prepaid, with the RA number clearly marked.
- Engineering Review: Our laboratory team will perform a failure analysis within 10 business days of receipt. We will provide a written report with a root-cause determination.
- Resolution: Approved claims will be resolved according to the table in Section 5.
5 Warranty Resolution Options
| Defect Type | Our Obligation | Timeline |
|---|---|---|
| Confirmed manufacturing defect - repairable | Repair at no charge + reimbursement of return shipping costs | 15–20 business days |
| Confirmed manufacturing defect - beyond repair | A replacement unit of the same or an equivalent model | 20–30 business days |
| Performance non-conformance (lab confirmed) | Replacement or full credit note | 20 business days |
| Defect caused by external factors | Repair quotation provided; warranty not applicable | Assessment within 10 days |
We reserve the right to use reconditioned parts of equivalent specification for warranty repairs. Replaced or repaired units carry the remaining warranty period of the original product, or 6 months from the repair date, whichever is longer.
6 Product Lifespan & Maintenance
Blauberg EC fans are engineered for a rated operational lifespan of 40,000–45,000 hours under specified conditions. This significantly exceeds the warranty period and reflects our commitment to long-term performance.
Recommended Maintenance Intervals
| Interval | Maintenance Action |
|---|---|
| Every 3 months | Visual inspection, check for unusual vibration or noise |
| Every 6 months | Clean impeller and housing, check mounting fasteners, inspect cable condition |
| Every 12 months | Full performance check, verify operating parameters against the datasheet, inspect motor temperature |
| Every 3–5 years | Bearing inspection and replacement (for non-sealed bearing models) |
