Motors • Explosion Proof Motors

Explosion-proof motors are designed for a use in applications where hazardous fumes or dust may be present  to prevent damage to equipment.

A type of AC or DC electric motor, an explosion-proof motor is used within industrial hazardous locations where fumes and dust are present. Typically available in three-phase and single-phase configurations, the motors are used in fans, blowers, pumps, and air compressors.Designs available include standard foot mounted, C face with base, C face less base, 60 Hz and 50 Hz, jet pump, and inverter drive. Explosion-proof motors typically range in horsepower from ¼ HP to 300 HP.
