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 discharge fan ESP series industrial smoke purification device utilizing mechanical filters and electrostatic separation technology, purification of smoke collected 0.01um minimum filtration accuracy level, due to the equipment low resistance, high purification efficiency, especially for heavy smoke large amount of wind occasions. Long-term use of non-consumable equipment, low energy consumption, low cost. Industrial smoke purification equipment is widely used in fasteners, heat treatment, metal processing, plastic processing, machine processing industry smoke purification. For example: cold heading machine, mesh belt furnace heat treatment, centralized purification of CNC machine tools, grinder bearing industry concentrated purified.
