Product Q&A

Q:What is the application of this FBD7.1/2*30kw fan?

It is professional mine local forced ventilation equipment, widely used for air supply and harmful gas exhaust in coal mine roadways, tunnel excavation and underground engineering working faces.

Q:What are the core parameters of this ventilator?

This fan features a 710mm impeller diameter and adopts dual 30kW motors. The counter-rotating double-impeller structure provides larger air volume and higher wind pressure for long-distance ventilation.

Q:Is this fan safe for gas-containing underground environments?

Yes. It adopts standard mine flameproof structure and strict explosion-proof processing, which fully meets underground safety requirements and is suitable for sites with low-concentration flammable gas.

Q:What are the advantages of counter-rotating design?

The dual counter-rotating impellers work without guide vanes, realizing higher ventilation efficiency, stronger air pressure and more stable air output than ordinary axial fans.

Q:Can the fan run continuously for a long time?

Absolutely. It adopts low-vibration optimized structure and thickened steel casing, supporting stable 24-hour continuous operation under harsh underground dusty and humid conditions.
