Frequent question: How do I know if my motor is explosion proof?

How do you know if something is explosion proof?

To meet the criteria for the explosion proof rating, an enclosure must be able to contain any explosion originating within its housing and prevent sparks from within its housing from igniting vapors, gases, dust, or fibers in the air surrounding it.

Is a Class 1 Div 2 motor explosion proof?

While Division 1 motors in Class I locations must be explosion-proof, Class II, Division 1 motors must be dust- ignition-proof. … One important distinction is that the enclosure of a dust-ignition- proof motor is designed to exclude hazardous materials.

Where are explosion proof motors used?

Explosion proof motors are designed for use in hazardous environments having certain explosive gases or materials present, like those found in the chemical, coal mining, textile, and petrochemical industries.

What is the difference between flameproof and explosion proof?

Explosion proof is an American Word. EExd is used by all EU. There is no difference except term. Flameproof design is one of the explosion protection technique extensively used for light fittings, JBs, motors in hazardous areas.

What makes an exhaust fan explosion proof?

The reason: explosion proof design requires isolation from the potentially explosive air. By nature of the way a fan operates, a potentially explosive air stream will always be in contact with the interior of the fan housing and the fan impeller.
