A coal Mine Explosion-proof Blower is a fan used in explosion hazard occasions, which must meet explosion-proof requirements in addition to the fan characteristics required by working conditions.

On the one hand, Coal Mine Explosion-proof Blowers must adopt explosion-proof motors; On the other hand, the overcurrent parts of explosion-proof fans (impellers, volutes, etc.) must be made of soft and hard materials, generally speaking, that is, between rotating parts and fixed parts, one soft and one hard to prevent sparks caused by friction or collision between components in the event of failure. The more common material combination is that the blades, front disc, rear disc and blade rivets of the impeller are duralumin made of 2A01 material, and the volute is made of galvanized sheet.

If the impeller is made of duralumin and does not meet the strength requirements, the galvanized sheet impeller can also be used, and the surface of the volute is covered with a thin duralumin lining.


With many years of industry experience, strong market adaptability, stable and reliable product performance, and rich and complete product line, we have won a good reputation in the Low Voltage Explosion Proof Universal Blower Motor industry, and our products have a strong competitive advantage in industry competition. In order to adapt to the new requirements of the global low-carbon economy, our company is constantly committed to research and development, production and sales of energy-saving environmental protection products. We continuously carry out model innovation and continue to promote technological progress.
