The purification type fresh air ventilator of this specific embodiment adopts metal G3 primary effect, the core body with the highest heat exchange efficiency, electronic electrostatic dust removal and gas filtration and adsorption technology to effectively control indoor PM2.5 particle pollutants, bacteria and gaseous pollutants . It has the following functions:

1.95% removal of fine dust in the air: using the principle of high-voltage electrostatic adsorption, it is still effective for pollutants as small as 0.01 microns (1/1000-1/10000 of the diameter of a hair, which can only be seen under an electron microscope), The effect of cigarette smoke and lampblack is particularly obvious.

2. The product design of large air volume and large capacity ensures that the use environment can achieve a considerable number of air changes and improve air quality.

3. A large amount of air vitamins --- light negative ions: the concentration is as high as 106/cm3, keeping the air in the air-conditioned room in a healthy state.

The first G3 metal primary filter of the fresh air ventilator has a metal frame structure and a large dust holding space of 20mm, which can effectively retain particle pollutants above 5 microns. The first two-stage electrostatic precipitation filter makes the particles in the air charged and captures particulate pollutants in a high-efficiency way; the first stage: ionization area: most of the large particles are intercepted by the pre-G3 metal primary effect; more Small particles arrive at the first section of the dust collection chamber with the airflow - the ionization section, and are ionized through a series of high-energy ionization wires - the working voltage is greater than 8000V. The second stage: dust collection area, the charged ions reach the dust collection area, and the charged particles are adsorbed on the dust collection plate with the opposite polarity - the working voltage is greater than 4000V, and the filtered clean air enters the gas filter.

The first activated carbon gas filter uses impregnated coal-based granular activated carbon. The impregnated activated carbon is a filter that can remove acid and alkali substances at the same time, permanently remove gaseous pollutants, and gaseous pollutants are absorbed and irreversible through chemical reactions. be removed.
