Something About Medium Efficiency Bag Filter Efficiency

People are getting more and more squeamish now. When it`s too hot, you stay in the air - conditioned room, and when it`s cold, you [take root" around the heating, and the demand for Filter Media For Air Conditioning is growing. Central air conditioning is installed in many public places, but few people know about it. Not to mention medium efficiency bag filters. In fact, it is an indispensable part of central Air Conditioner Filter Media.

The working principle of the medium - efficiency bag filter: Inertia and diffusion: The particle dust performs inertial motion in the airflow. When encountering a messy fiber, the airflow will change direction, and the particle inertia will deviate from the direction, hit the fiber, and bond together. The larger the particle, the easier it is to collide, and the better the effect. Small particles of dust do irregular Brownian motion. The smaller the particle, the more severe the irregular motion, the greater the probability of encountering obstacles, and the better the filtering effect. Particles smaller than 0.1 microns in the air mainly undergo Brownian motion, and the particles are small and the filtering effect is good. Particles larger than 0.3 microns mainly perform inertial motion. And the larger the particle, the higher the efficiency. Both diffusion and inertia are unknown, and the particles seem to be the most difficult to filter. When measuring the performance of high - efficiency filters, people often specify the most difficult to measure dust efficiency values.

Electrostatic effect of medium - efficiency bag filter: For some reason, fibers and particles are charged, resulting in electrostatic effect. The filtering effect of electrostatic filter materials can be greatly improved. Reason: Static electricity will make the dust change its trajectory, and when encountering obstacles, static electricity will make the dust adhere to the medium more firmly. Materials whose electrostatic energy lasts for a long time are also called electret materials. The material has static electricity, the resistance remains unchanged, and the filtering effect is obviously improved. Static electricity has no decisive role in the filtering effect, only an auxiliary role.
Regularly check whether the inflow surface of the Air Filter Material is blocked by debris and whether the surface of the filter is damaged. If something is blocking the surface, remove it. If the surface of the filter is badly damaged, it will need to be replaced with a new filter or replaced with a new filter to reinstall. 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 of the filter pocket should be perpendicular to the ground to ensure the filtering effect of the air supply and prolong the service life.
Under the condition of rated air volume, the filter should be replaced within 3 to 4 months. When cleaning the filter, it can be washed with a solution containing water or neutral detergent, cooled and then replaced. It can be cleaned up to twice. That is, the filter needs to be replaced with a new one. If the dust concentration in the use environment is high, the service life cycle will also be reduced.
