With the clinical application of new diagnosis and treatment of medical instruments and new drugs, so that nosocomial infections growing, not only resulted in patient days lengthen and increase spending in the economy, but also a direct threat to the patient's life and health, affecting the quality of care, according to It reported that the US air because hospital infections spending $ 10 billion a year ducted air purifiers offer, in our country, about a quarter of hospital deaths are the direct and indirect causes of death and hospital air infection. Our health care environment of human traffic is very large, which carry the virus population is much higher than in other public places, the traditional spray disinfectant, ozone sterilization and other methods can not fully meet the needs of the new era of health care institutions need to be able to efficiently Wei, a virucidal disinfection purification equipment ducted air purifier, to ensure the health and safety of health care, and the need to enhance the air quality within the health care environment, the medical staff to provide a safe and healthy environment clean. Wei, a return air air purification systems Profile: ◆ broad-spectrum bactericidal, effectively kill harmful microbes, bacteria, viruses ◆ decomposition of volatile organic compounds: benzene, formaldehyde, alcohol, TVOC and other chemical organics; ◆ eliminate odor: it can effectively be eliminated by the body breathing, sweat, urine, body mildew, rot and other chemical reactions odors; the elimination of waste, sewage pumping stations, chemical plant odors. Wei, a central air purifier VBK-H return air type air cleaner device product functions and features ◆ patented semiconductor disinfection purification technology: air conditioning by the National Testing Center, and the drag of only 6.3Pa ducted air purifier supply, in line with < > standards; ◆ high disinfection efficiency: patented technology: The Chinese Center for Disease Control ducted air purifier Which is good, one natural bacteria killing efficiency of 72%, continuing the cycle kill rate of 99%, in line with national health and Family Planning Commission, "disinfection technical specifications"; ◆ broad-spectrum bactericidal, effectively kill harmful microbes, bacteria, viruses ◆ decomposing volatile organic compounds: benzene, formaldehyde, alcohol, TVOC and other chemical organics; ◆ eliminate odor: can effectively be eliminated by human breathing, sweat, urine, body mildew, rot and other chemical reactions odors; the elimination of waste, sewage pumping stations, chemical plant odors. ◆ Settlement of respirable particulate matter: dust containing negative ions functional settlement, the settlement of various respirable particulate matter, dust, smoke, dander, the solid sulfide, Solid Carbide, etc., to 0.01 micron particles. ◆ air volume based on customer requirements, can be flexibly combined size flexible, can be installed in different positions. ◆ automatic operation, constant high pressure, and air conditioning linkage.
