The filter principle of F9 medium effect bag filter is explained in detail

F9 efficiency bag filter is needed in many occasions, especially in the production of high requirements for the filter, can filter out impurities, retain the better quality of the part, so as to bring help to the subsequent production, of course, the choice of filters is also very important, now on the market there are many types of filters, for different types in the role of different, Nature has also brought different effects to the actual use, and today I will take you to detail the filtering principle of the filter:

F9 Medium effect bag filter

The inertia and diffusion of particle dust in the air flow for inertial movement, when the arrangement of cluttered fibers, the direction of the air flow changes, the particle due to inertia deviate from the direction, hit the fiber and be bonded, the larger the particle the easier the impact, the better the effect.

Small particles of dust for irregular Brownian motion, the smaller the particles, the more violent the irregular movement, the more chance of hitting obstacles, the better the filtration effect will be, particles less than 0.1 micron in the air mainly for Brownian motion, small particles, good filtration effect.

Particles greater than 0.3 microns are mainly used for inertial motion, the larger the particle efficiency is higher, the diffusion and inertia are unknown, the particles are the most difficult to filter out, when measuring the performance of high efficiency filters, people often specify the most difficult to measure the dust efficiency value.

Electrostatic effect of bag filter in F9 For some reason, fibers and particles may be charged, resulting in electrostatic effects. The filtration effect of the filter material with static electricity can be significantly improved.

Cause: static electricity makes the dust change the movement trajectory and hit the obstacle, static electricity makes the dust stick more firmly on the medium, the material with long-term static electricity is also called "electret" material, the resistance of the material with static electricity is unchanged, the filtration effect will be significantly improved, static electricity does not play a decisive role in the filtration effect, only plays an auxiliary role. In the future, there are new topics about filter expertise to share with you!

F9 Medium effect bag filter

Air filters are recognized by more and more people, it improves air quality and ensures people's health, and has been widely used, such as medicine, food and other industries are inseparable from all kinds of efficiency filters.
