New Air Purifiers Ionizer Airborne Negative Ion Anion Generator Module DIY Tool Description: Working Principle: By using pulses and vibration of electric appliances, rise the original low voltage to DC high negative pressure. Making use of DC high voltage of carbon brush tip to produce high corona, emitting large amounts of electronic at a high speed. Electronics can not remain in the air for a long time, therefore,after reacting with oxygen molecules in the air , negative ions will form. Features: 100% brand new and high quality Air purification, dusts coagulation, smoke elimination. Odor removal (most of), release from fatigue, prevent from air-conditioner disease. Adjust sleeping level. Specification: Type: Double-headed with bracket PK-A22F Power Supply: Car Power Applicable Area: 11-20 Air Purifier Volume: 50m/h Input voltage: AC220V Output voltage: DC-3.5KV1.0KV Negative ion concentration: 6x106PCS/cm(Test at 100mm) Insulation resistance: 40M(500V DC) Dielectric Strength: AC3000V 50Hz 5mA Rated Power: 1W Input Current: 10mA Ozone Concentration: 0.05PPM Working Temperature: -10~50 Working Humidity: 35%~85% Storage Temperature: -20~50 I/P: AC110-220V O/P: -DV2.0~6.0KV Material: ABS+Silicone Line Dimensions: 32x15x20mm/1.26x0.59x0.79''(approx) Color: Black Quantity: 1 pc Note: Transition: 1cm=10mm=0.39inch No retail package.
