Principle and characteristics of high efficiency filter

High efficiency filter is a popular purification equipment and an indispensable part of industrial environmental protection. As a new type of purification equipment, the characteristics of high efficiency filter is that it can trap 0.1 - 0.5um fine particles, even for other pollutants also have a good filtering effect, so that because of our environment to increase a safety guarantee.

The role of the filter layer of the high efficiency filter to trap particles are mainly 4 kinds.
First, the interception effect: when a particle size movement to the fiber surface near the center line to the fiber surface distance is less than the particle radius, the particles will be intercepted by the filter fiber and deposited.

Second, the inertia effect: when the particle mass or speed is larger, due to inertia and collision to the fiber surface and deposited.

Third, the electrostatic effect: fiber or particles may have an electric charge, the electrostatic effect of attracting particles and particles will be adsorbed.
Fourth, diffusion movement: small particle size example of Brownian motion is stronger and easy to collide with the surface of the fiber and deposited.
With the increase in the amount of filter particles, the filtration efficiency of the filter layer will decline, and the resistance increases, when the increase to a certain value should be replaced in time to ensure cleanliness.
Most of our common high-efficiency filter equipment is made of aluminum alloy outer frame without partition, so that the equipment is not only well sealed, but also the filtration is not allowed to leak. The industrial high efficiency filters are better resistant in structure, corrosion and heat resistant. The filter material of high efficiency filter is made of ultra-fine glass fiber paper, which does not spare any tiny particle material, making our environment cleaner and industrial production safer.
The high efficiency of the high efficiency filter can reach 99.999%0.3um, and it is under normal working condition. Because of the high efficiency work, the high efficiency filter has been widely used in many industries, especially pharmaceutical filtration, food filtration, electronic filtration, etc.
