The history of air filters

- Dec 21, 2017 -

Glass fiber is used for filter material of high efficiency filter,The range of filter materials used in chemical fiber is also gradually increasing. The outer frame is mainly used: aluminum alloy profile, multi-laminated frame, aluminum plate frame, galvanized steel plate frame,The most used is aluminum alloy section frame,main product formation structure.

The main use of hot sol as the separator of filter core is easy to mechanize production. In addition, it has the advantages of small size, light weight, easy installation, stable efficiency and uniform wind speed. In addition, compared with the rectangular channel with baffle filter, the v-shaped channel of the no-baffle filter further improves the uniformity of the dust and extends the service life. Ventilated with no baffle filter can avoid the use of metal parts, easy to waste treatment, meet the increasingly strict environmental protection requirements. In addition to some special occasions for high temperature and high safety requirements, no baffle filters can replace the filter.

No diaphragm filter works mainly dust particles in the air for inertial movement, when encounter arranged disorderly and fibre, air change direction, because of inertia swerve, and bumped on fibre by adhesive. The bigger the particle, the better the impact.

Small particle dust is a no-rule Brownian motion. The smaller the particle, the greater the unrulable motion, and the more chance of bumping into an obstacle, the better the filter effect will be. Particles smaller than 0.1 micron in the air are mainly Brownian motion, with small particles and good filtering effect. Particles larger than 0.3 microns are mainly used for inertia, and the larger the particle is, the more efficient it is. Diffusion and inertia are not known to be the most difficult to filter out. When measuring the performance of high efficiency filters, it is often prescribed that the measurement of the most difficult to measure the efficiency of the dust.
