The main structure of the air purifier: In general, indoor air purifier is the case, the purification section, fans, electric appliances in four parts. The main structure of the air purifier: clean parts: the main function of a variety of filters, by combinations in different ways for different air pollutants to achieve air purification. APS-628, Basic configuration instructions: 1. Japan Shibaura DC; 2. State standard filter configurations: 4-5 layer standard filters (pre-filter, formaldehyde activated carbon filters, cold catalyst, photocatalyst, thick 4CM HEPA filter); 3. Imported negative ion generator; 4. The United States GE (OW) sensors; 5.LED touch screen (switches, air volume, pattern, ultraviolet, negative ions, timing); 6. Acrylic control panel; 7.5 stall speed control ; 8.PM value is displayed; 9. anion purification, ultraviolet disinfection ⑥ anion purification; 10. intelligent child lock design (no operating within a one-minute, enter the child lock mode; wind 5 seconds to unlock the key press) 11. Infrared remote remote control design (with LED panel key functions correspond exactly); 12. Air quality four-color display (blue - very good, green - good, purple - in general, red - poor); APS-628 type basic parameters: Rated working Voltage: AC 220V / 50HZ operating voltage range; AC 180V ~ 250V / 50HZ Working temperature: -20 ℃ ~ 80 ℃ Operating humidity; ≤85% rated power: 30W purify air volume: 80-360 cubic meters / hour Power cord length : 1.6m Weight: 6.4kg Application area: 60 square meters six filters: ① pre-filter activated carbon filter ③ ② cold catalyst filter ④HEPA efficient ultraviolet disinfection filter ⑤ ⑥ anion purification Dimensions: 650 * 340 * 250 (mm) PM2.5 removal: 99.9% germs Purification rate: 97.6% particle removal rate: 99.9% formaldehyde removal rate: 99.9% APS-628-type main structure Description: Motor: Brushless DC motors: high reliability, no commutation spark, mechanical noise low, long life, energy saving and other advantages. Dust sensors: is detected dust in the air (such as PM2.5, PM10) concentration sensor using optical methods. Use Brand: GE negative ion generator: a means for generating aeroanion imported from Japan.
