explosion proof motor can be used in inflammable and explosive places, which does not produce sparks when the motor is working.
Be widely used in fields and industries, such as coal, mine, petroleum, petrochemical, chemical, textile, metallurgy, city gas, transportation, grain & oil processing, paper making, medicine and others.
At the same time, as major drive equipment, this is often used to drive pumps, fans, compressors and other mechanical transmission and other machines.
With the advantage of higher efficiency, long working life, energy saving, high starting torque, low noise, small vibration, big breakaway torque, reliable operation performance, and convenient  maintenance.
It can be equipped with re-greasing system when the motor frame size is 160MM and above.
