Common high temperature resistance on the marketAir FilterHow does it work? What are the characteristics?

There are a lot of filtration equipments around us, with them, we will gain better filtration effect. So next I will introduce to you about high temperature resistantAir FilterThe use of the product and the characteristics of the product is introduced, I hope it can help you.

High temperature resistant air filter is a partition structure, using high temperature resistant glass fiber or ultrafine glass fiber filter paper, aluminum foil partition, stainless steel frame, special high temperature resistant sealant sealing assembly, each unit has been rigorously tested. Efficiency up to F9-H14. currently used materials are glass fiber, polypropylene fiber, polyester fiber, plant fiber, etc.. With the dust hitting the filter media to explain the law of motion, the common filtration mechanism is divided into the principle of inertia, diffusion principle, electrostatic force. Large particles of dust in the airflow for inertial movement. Airflow encounter obstacles around, dust due to inertia deviates from the direction of airflow and hit the obstacles. The larger the particle, the stronger the inertia force, the greater the possibility of hitting the obstacle, so the better the filtration effect. Small particles of dust for irregular Brownian motion. The smaller the dust, the more violent the irregular motion, the more chances to hit the obstacles, so the better the filtration effect.

There are some fine particles of dust in the air, mainly to do Brownian motion, the smaller the particles, the higher the efficiency of the filter; large particles of dust mainly for inertial movement, the larger the particles, the higher the efficiency of the filter. Diffusion and inertia effect is not obvious in that part of the dust is difficult to filter, the filter performance, filtering efficiency of the efficiency of the low point of the representative value. If the filter material with static electricity or dust with static electricity, the filtration effect can be significantly improved. There are two main reasons: electrostatic dust to change the trajectory and hit the obstacle; electrostatic force to make the dust in the media to stick more firmly.

Filter resistance The captured dust creates an additional resistance to the airflow, and the resistance of the filter increases gradually during use. The captured dust and the filter media become one and form additional obstacles, so the filtration efficiency of the high-temperature air filter in use will also be increased. Most of the captured dust is gathered on the windward side of the filter material. The larger the area of the filter material, the more dust it can hold and the longer the service life of the filter. The more dust that accumulates on the filter material, the greater the resistance. When the resistance is unreasonably high, the filter is scrapped. Sometimes, too much resistance can cause the dust that has been captured on the filter to fly away, and when there is a danger of this, the filter should also be scrapped.

The product characteristics of high temperature resistant air filters are as follows:

(1) Made of glass long fibers, uniformly laminated in a non-textile manner.

(2) It can be cleaned repeatedly and the filtration efficiency is not affected.

(3) Good chemical resistance, low moisture absorption and long service life.

(4) Protective prefiltration for air conditioning and ventilation systems.

(5) The outer frame can be selected from galvanized iron frame and stainless steel frame according to demand.

(6) Specification size: can be customized according to the customer's needs for the purpose.

(7) Flame retardant, high temperature resistance up to 450°C.

(8) General coarse dust filtration, and hot air type high temperature oven.
