What should I do if the impeller is severely worn?

A: For abrasive dust, we can apply tungsten carbide hard-facing treatment on the impeller blades.

Do you conduct dynamic balance tests before delivery?

A: Every fan undergoes 3-axis vibration analysis and dynamic balancing at actual operating speeds.

Does installation require professional personnel?

A: We provide detailed guides. The fan is skid-mounted, so general mechanical staff can handle installation.

Can you provide fan system design?

A: Yes, our engineers can assist with duct pressure loss calculations and selection optimization.
