The rapid development of the cartridge filter housing is closely related to the development of military industry and electronic industry. During the first world war, due to the use of cartridge filter housing of various chemical agents, the asbestos fiber filter paper as cigarette filter layer military gas mask arose at the historic moment. Glass fiber filter medium for air filtration in October 1940 in the United States got the patent. In the 50s, the United States made a deep research on the production process of glass fiber filter paper and made the cartridge filter housing improved and develop. In the 60s, HEPA filters were available. In the 70 s, using fine glass fiber filter paper as filter medium, HEPA filters' filtering efficiency had achieved 013 microns in diameter as high as 99.98%. Since the 80s, with the emergence of new test method, evaluation improved the filtering performance requirements. People found the HEPA filter a serious problem, so cartridge filter housing had a higher performance. At present, countries are still trying to study and it is estimated that soon there will be a more advanced air filter.
The design of cartridge filter housings working principle itself also has made significant progress. And the most important of these is a partition. No diaphragm filter can not only eliminate the risk of damage of division plate filter medium, but also effectively increase the filter area and improve the filtering efficiency. Besides, cartridge filter housing can reduce the air resistance, thereby it can reduce the energy consumption. In addition, the cartridge filter housing equips with high temperature resistance, corrosion resistance and waterproof to prevent bacteria, which also takes a lot of progress and meets some special needs.
About the cartridge filter housings working principle, there are also some disadvantages. The compressed air out of the air source contains excessive amounts of water vapor, oil as well as solid impurities such as rust, sand, pipe sealant, etc. It will damage the piston sealing ring, plug components on the small vent or shorten the service life of components. The role of the cartridge Filter housing is to separate liquid water from compressed air and liquid droplets and to filter the dust in the air and solid impurity, but it is unable to get rid of gas oil and water.
