1.Ingenious design Unique range hood design, incorporating extraction functions of normal ventilation hoods and purification functions of Electrostatic Precipitator (ESP), or Cottrell precipitator, where high voltage electrostatic fields are applied to generate more then 100 millions per cubic centimeter of electrons to capture airborne cooking oil fume & grease particulates. Patented cylindrical honeycomb electrostatic fields and optional PLC controlled spray-style humidifier, maximizing the filtration and purification efficiency of cooking oil fume and grease particles for commercial kitchens. Modular design, ensuring easy assembly of our Exhaust Hood with Air Purification Electrostatic Precipitator for total operation and easy removal of the hood, the cover, the control panel, the electrostatic precipitator, and other major components for maintenance and cleaning. 2. Remarkable purification efficiency An average purification efficiency of above 95%, based on 2 stages of electric field applied in our exhaust hood ESP air purifier, is guaranteed. 3. Broad-spectrum applications Our Exhaust Hood with Air Purification Electrostatic Precipitator is ideal exhaust ventilation & air purification equipment for large commercial kitchens in restaurants, hotels, supermarkets, shopping centers, business centers, enterprises and business organizations, etc. 4. Strict Quality Control ISO9001:2000 tested quality control system. CE (certificate of safety conformity) granted, UL867, UL710 and IEC60335 tested, ensuring the internationally standard safety and reliability of our exhaust hood ESP air purifiers. 5. Cost Effective Can be installed directly above the cooking stoves, no additional purifying equipment needed to dispose the secondary air pollution, saving your kitchen space and overall cost. PLC controlled flame detection device and water fire-suppression system, plus the optional self-cleaning device, easy to realize remote control and mmonitoring, ensuring considerable savings in maintenance cost. PLC controlled multi-choice operational modes, secure and reliable high-efficiency high-voltage power supply, complemented with the sophisticated system of self-diagnosis of malfunction, enssuring considerable energy savings. Spare electrostatic fields are seldom needed for replacement, adding much to the savings in maintenance cost. 7. Hassel-free One year free repair and lifelong maintenance of our exhaust hood ESP air purifier guaranteed. Low altitude emission of the processed air guaranteed, no complain will be incurred. No ozone generated during the operation of our Exhaust Hood with Air Purification Electrostatic Precipitators.
