1. it can automatically remove dust and the filter can be clean automatically. The efficiency of removing dust can be stabilized for long time. This is very helpful to provide clean air, also can save lots of fees to clean the ventilated pipeline.
2. Oxygen anion can reach to 80,000-500,000/ cm3. this can accelerate metabolism, remove tiredness, improve immunity abilily and so on.
3. Both new wind and circle wind are clean and sterilizating synchronously, this can radically sterilizate the virus and bacteria, and is effective to obstruct spread of micororganism. Otherwise, formaldehyde, toluene, ammonia, smoke and other life odour can be removed.
4. it can save energy and protect central air condition effectively. This can increase the efficiency greatly.

1. NCL initially create the sterilization and clean system in the mixed range of new wind and circle wind of central air condition, this system did not include the equipments, such as ultraviolet radiation and static removing dust et al. it mainly include abstersion to remove dust, and also adds biology enzyme et al in the abstersion liquid. This can quickly remove some polluted gaseous. After that, nickel-titanium-aluminium catalyst filter and given light are also used to sterilizate the virsus, bacteria, and polluted gases.
2.we can design sterilization and clean equipment or alteration of central air condition according to the requirements of different clients.
3.The indoor air quality guaranteed to reach the related national criterion.
4.we will provide free upgrade scheme of sterilization when new virus or epidemic breaks out.
