Wei, a central air purifier fan coil air purifiers, light hydrogen ions purification devices, a product flexible, capable of the duct air flow dynamic disinfection, reducing the possibility of bacteria and viruses spread through the air to cross, but also through static light disinfection to prevent excessive bacterial spores filter and heat exchange coil surface, the propagation of mold. 2. The product is equipped with working lights, real-time monitoring of the operational status of core electrical components to ensure that the product is effective working condition. 3. Using high-performance anti-jamming electronic ballasts, through a national mandatory product EMC EMC monitored. 4. According to on-site installation space, the flexibility to adjust the product installation hole location and orientation, can open manhole at the side of the duct, if necessary, to ensure that the installation and maintenance are very simple. 5. fully enclosed structure design product, box joints are equipped with flexible seal to ensure leak wind, no UV leakage, the use of absolute safety. 6. Optional new generation of nano photocatalyst air purifier equipments hotel fan coil air purifiers, odor and organic contaminants for significant purification. 7. Since there is no duct box, product installation more flexible. Products equipped with a module to strengthen the board as a reference hole in the wall, so opening the operation easier and more standardized fan coil air purifiers offer, the installation process easier.
