Oil mist and smoke produced EP cleaner for oily mist cutting fluid purification and recovery process when, for a variety of pure oil mist fumes machining: Bolt cold heading machine, thread rolling machine, CNC lathes, machining centers, CNC grinding machines, hobbing machine, walk-core machines. EP oil mist cleaner electrostatic principle, inhaled fumes from industrial pollution in the air mist contaminants, after pre-filter larger particles are separated from the pre-filter, then through the ionizer ionization corona discharge is contaminated charged particles in the air, charged pollution particles in the air and then into the collector industrial pollution when charged particles in the air by the electric field will be Coulomb force generating steering and is adsorbed to the metal plate, thereby separating the particles from the polluted air out through the rear air filter, and the charged particles escaping air, clean air is formed by the fan discharge.
