Are the purged and pressurized motors explosion proof?
No. The term “explosion proof” means that the motor is capable of withstanding and containing an internal explosion. The concept of the purged and pressurized motor is to eliminate the explosion risk by keeping the hazardous materials outside the motor. Empire Magnetics purged and pressurized motors are designed to work within a system that meets the National Fire Protection Agency (NFPA) requirements for class I, II, and/or III environments (see NFPA 496, “Purged and Pressurized Enclosures for Electrical Equipment in Hazardous Locations”).
