About the characteristics and principles of the resident electrode purifier


Design Features of Resident Electrode Purifier

1. It is a good solution to balance the filtering power and pressure difference.

2. Open channel micro-imitation structure, electrostatic electret material.

3. Pure synthetic fiber, resistant to moisture and general chemicals.

4. Self-supporting filtration, no need for additional brackets.

5. After making protrusions and grooves on the surface of the film, our unique fiber imitation skills ensure that the SEAP filter has a huge external volume, which can more effectively capture and carry particles.

6. The unique electrostatic technology can make the static electricity on the filter material durable, and the charge density is extremely large, which can effectively use electrostatic attraction to capture particles.

The basic principle of the resident electrode purifier:


The pre-filter is very thin, with a thickness of 10mm, and the selected material can be cleaned with low resistance.

Particle charge

A thin metal plate and an alloy electrode are used. The needle-mounted electrode is located at the center of each round hole. The needle tip and the edge of the round hole produce a corona discharge. The dust particles and bacterial particles in the air are charged when flowing through the hole.

Particulate adsorption

The charged air particles flow into the honeycomb-shaped dust collection area, which is a dense strong electric field with a dielectric as a carrier. The pre-charged dust particles and bacterial particles are adsorbed on the inner and outer surfaces of the hollow wall under the action of a strong electric field.

Planning features

Safe and harmless: From raw material selection, process preparation to terminal purification, the entire chain has clear ingredients to ensure safety and harmlessness;

Purification: The purification rate of indoor main gaseous pollutants has reached more than 95%;

Long service life: the adsorption capacity of the main gaseous pollutants in the room reaches more than 5‰ (mass percentage), and some gases reach 10‰ (mass percentage);

Broad-spectrum purification: can simultaneously remove formaldehyde, TVOC, benzene, benzene, ozone, hydrogen sulfide, etc.;

High strength: The compressive strength of the active composite module in multiple dimensions reaches more than 2Mpa;

Low attenuation: strong resistance to environmental disturbances, the performance attenuation value is lower than 10% at a temperature scale of -20℃~80℃ and a relative humidity scale of 0~95%.
