Great support team

I had many questions before sending our rotors. The support team explained the process clearly and helped us prepare the components correctly. The final balance quality met our strict G2.5 requirement.

Professional service, quick turnaround

The team was very professional and completed the dynamic balance testing faster than expected. The only minor issue was communication time zones, but the technical results were spot on.

Excellent precision for our large industrial fans

We sent three large centrifugal fans to the Jinan facility for balancing. The vibration levels dropped significantly after their service. The report was detailed and easy to understand. Highly recommended for heavy machinery.

5 FAQ

Q: Can you balance assembled impellers or do they need to be stripped?

A: We prefer testing assembled impellers to account for fitment variances, provided the assembly is safe to rotate at test speeds. However, we can also balance individual components if required.

Q: What is the maximum speed you can test at?

A: Our current rig supports testing speeds up to 3000 RPM for standard industrial fans. For high-speed applications, please contact us with your specific rotor specifications for a feasibility assessment.

Q: Is the calibration certificate included in the price?

A: Yes, all testing includes a calibrated measurement report traceable to national standards. A formal calibration certificate for the machine itself is available upon special request.

Q: Do you provide pickup and delivery services for the fans?

A: Yes, we can arrange logistics for pickup and delivery within Shandong province. For national shipping, we can coordinate with third-party freight carriers upon request.

Q: How long does the actual testing process take once received?

A: Once the item is checked in, the actual balancing process typically takes 24 to 48 hours depending on the complexity and weight of the rotor. Total turnaround including reporting is usually 3 days.
