Power system dynamic part of the fresh air ventilator is used in high-efficiency, lower noise fan. The filtered, purified and heat exchange process mandatory outdoor fresh air into the room, while the filtered indoor harmful gas purification and heat exchange process after mandatory exhausted to the outside. Filtration system filtration system into fresh air ventilator early effect, in effect, sub-efficient and highly efficient four filters. Ventilator settings were both at the inlet air filter can effectively filter the air of dust particles, fibers and other impurities, effectively prevent outdoor airborne dust and other impurities into the interior achieve the purpose of purification, and to ensure that the host's hot exchange member is attached dirt affect device performance. Features five new wind ventilators, safe and reliable low-noise fan and internal noise reduction processing, to prevent interference to the scene, the whole fan with no moving parts except for the smart new wind ventilators, can ensure long-term stability of the best smart new wind change qi, once and for all. 6, filter automatic alarm device (optional) when the air filter to accumulate a lot of dust smart new air ventilator professional providers, need to clean or replace the filter, the machine automatically display alarm. 7, intelligent control (optional) advanced liquid crystal display technology, intelligent control, indoor air quality status at a glance, intelligent control ventilation mode; winter using a heat exchange 'Spring using bypass type. 8, application equipment inside the main components of the materials used flame-retardant materials are used in new fire-retardant materials, precautionary measures to not "burn." 9, silver ion antimicrobial mold filter using the most advanced nanotechnology, the silver surface parcel carrier or adsorbed in a carrier branded smart new wind ventilators, slow release of silver ions, resulting in long-lasting, efficient and safe antimicrobial effect . Reusable, safe, non-toxic environmental pollution, good thermal stability. 10, the new air filtration and purification filtration purification compliance with building regulations. Equipped with different levels of purifying filter can effectively prevent dust and harmful gases and other pollutants into the interior.
