Waterproof and oil resistant seven ear quick detachable dust filter cartridge 200 * 500The filtration mechanism of filter media mainly includes interception effect, gravity effect, inertia effect, diffusion effect, electrostatic effect, etc. Interception effect: The arrangement inside the filter material is intricate and intertwined, with a small average pore size. Particles larger than the pore size of the filter material cannot be intercepted through the gaps between the filter layers. Gravity effect: Large particles of dust have a high gravity and may settle directly without passing through the filter material, or particles attached to the filter material may agglomerate and experience increased gravity, causing them to detach from the filter material after vibration. Inertia effect: Powder particles move with the airflow, and the airflow encounters obstacles and detours. Dust deviates from the direction of the airflow due to inertia and collides with the filter layer, and is collected. The larger the particles, the stronger the inertia force, and the greater the possibility of being filtered out. Diffusion effect and electrostatic effect: Fine dust collides with the filter layer, and the attraction between the dust and the surface of the filter material causes it to stick to the filter material and be filtered out. Particles with smaller diameters undergo Brownian motion and collide with each other. Small particles collide with each other or are charged by friction with the filter material, attracting and capturing the particles. Large particle dust is mainly dominated by the first few filtration mechanisms, while smaller particle sizes are mainly used by the latter few. Multiple filtering mechanisms work simultaneously, so that most of the dust will be filtered out, and the dust removal efficiency of the dust collector will also be higher.

The most critical factor for a dust removal filter cartridge is the filter material. Domestic 240g polyester long fiber filter material is one of the widely used filter materials in the dust removal industry. Jiangxi Guoqiao and Silep are currently the manufacturers of domestic products. Filter materials from other manufacturers must be used with caution, and of course, 220g or 200g cannot be used as substitutes, as this will shorten the service life of the filter cartridge. It is best to choose a thick pure cotton material for fixing the straps between paper folds. The adhesive used to fix the straps cannot be bonded with ordinary hot melt glue, otherwise your filter cartridge will be blown out like a balloon. In addition, you also need to understand the properties of dust: ordinary dust, ultrafine dust, humid dust, or flammable and explosive dust. We will perform different post-processing on the filter media according to the needs of dust properties, such as metal aluminum coated anti-static filter media, chemical layer oil and waterproof filter media, PTFE coated filter media, flame retardant filter media, etc. This is an important choice, otherwise it may cause trouble or even major accidents for you. Of course, even better options are 260 grams from Japan's Dongli and 270 grams from South Korea's Kelon, as the production process of filter materials from overseas is still superior to that in China. Once the filter material is set, it is necessary to determine the number of folds or effective filtering area of your filter cartridge, which will determine whether the processing air volume of the filter cartridge matches that of the entire dust collector. Otherwise, either the dust removal effect of the dust collector is poor or the filter cartridge has a short lifespan. Next is the end cap and support net. The end cap should be made of high-quality sheet metal with a thickness of 0.7-0.8 millimeters to increase the overall strength of the filter cartridge. The support net should not be careless, and a diamond shaped support net with a thickness of 0.8 millimeters should also be selected to ensure that the filter cartridge will not be sucked down during reverse blowing. Next is the adhesive. The adhesive for the dust removal filter cartridge must be selected from high-quality specialized adhesive, and the injection amount must be sufficient. Unlike the air filter cartridge in cars, which has relatively lower strength requirements, the dust removal filter cartridge will have a continuous pulse cleaning pressure of 6 kilograms running through the filter cartridge during operation. Therefore, if the adhesive is not good or the injection amount is too small, the end cap of the filter cartridge is prone to falling off. Finally, there is the sealing strip and packaging. Sealing strip is also crucial. Poor sealing strip can cause poor sealing between the filter cartridge and the flower plate, resulting in dust leakage directly without passing through the filter cartridge. Dust removal filter cartridges are generally bulky, and if the packaging box is not secure, it can cause damage to the filter cartridges during transportation.
