Product Description

YFB3 series dust explosion-proof three-phase asynchronous motor is fully enclosed self-fan-cooled squirrel cage three-phase asynchronous motor. It is characterized by small volume, light weight, reliable operation and beautiful appearance. 
It also has the advantages of high efficiency, low noise, low vibration, large temperature rise margin, good performance, advanced and reasonable explosion-proof structure, safe and reliable use, and so on.
 
Dust explosion-proof motor is mainly used in pharmaceutical, textile (such as cotton fiber, flax fiber, chemical fiber, etc.), metallurgy (magnesium powder, aluminum powder, carbon powder, etc.),  grain processing (such as wheat, corn, grains, etc.), feed processing (blood meal, fish meal), fertilizer, Tobacco, paper making, synthetic materials (such as plastics, dyes), building materials and other places where combustible dust exists.

Explosion proof products have obtained domestic explosion-proof certification, energy efficiency certification, CCC certification, international IECEx certification, ATEX certification, CUTR certification, etc., and have strong domestic and international competitiveness.
