People nowadays are becoming more and more delicate. When it's too hot, stay indoors in air-conditioned rooms, and when it gets cold, the heating system takes root and sprouts. The demand for air conditioning is increasing. Many public places install central air conditioning, but few people know about it. Not to mention the medium efficiency bag filter. In fact, it is an indispensable part of central air conditioning. Below, the editor will introduce it to everyone.

The working principle of a medium efficiency bag filter: inertia and diffusion: particles and dust move in an inertial motion in the airflow. When encountering cluttered fibers, the airflow will change direction, causing the particle inertia to deviate from the direction, impact the fibers, and bond together. The larger the particles, the easier they are to collide and the better the effect. Small particles of dust undergo irregular Brownian motion. The smaller the particles, the more severe the irregular motion, the greater the possibility of encountering obstacles, and the better the filtering effect. Particles smaller than 0.1 microns in the air mainly undergo Brownian motion, with small particles and good filtering effects. Particles larger than 0.3 microns mainly undergo inertial motion, and the larger the particle, the higher the efficiency. Both diffusion and inertia are unknown, and particles seem to be the most difficult to filter. When measuring the performance of high-efficiency filters, people often specify the most difficult dust efficiency value to measure.

The electrostatic effect of medium efficiency bag filters: Due to certain reasons, fibers and particles can carry charges, resulting in electrostatic effects. The filtering effect of filter materials with static electricity can be greatly improved. Reason: Static electricity can cause dust to change its trajectory. When encountering obstacles, static electricity can make dust adhere more firmly to the medium. Materials that can sustain static electricity for a long time are also known as polarizable materials. The material has static electricity, the resistance remains unchanged, and the filtering effect is significantly improved. Static electricity does not play a decisive role in the filtering effect, only an auxiliary role.

Regularly check if there are any debris blockages on the inlet surface of the filter and if the filter surface is damaged. If something blocks the surface, it should be removed. If the surface of the filter is severely damaged, a new filter needs to be replaced or reinstalled. When installing the filter, it should be well sealed with the pressure edge of the frame to prevent air leakage, and ensure that the length direction of the filter pocket is perpendicular to the ground to ensure the filtering effect of the air supply and extend the service life.

Under rated air flow conditions, the filter should be replaced within 3 to 4 months. When cleaning a filter, it can be rinsed with a solution containing clean water or neutral detergent, cooled, and then replaced. You can clean it up at most twice. That is to say, a new filter needs to be replaced. If the dust concentration is high in the usage environment, the service life cycle will also be reduced.

At present, the utilization rate of central air conditioning is increasing, but few people understand its working principle. The above is the information about medium efficiency bag filters. Including its working principle, precautions during use, replacement cycle, etc. We hope that after understanding these, it can be helpful to everyone!
