Classification of air filter elements

At present, the filters on the market can be roughly divided into three categories according to different filter types: oil filtration, water filtration, and air filtration. Among them, air filtration is mainly used in the air compressor industry. Its function is to remove impurities in the air and protect The normal operation of the equipment and the cleanliness of the air. The operation process is that after the air passes through the filter element of a certain precision, the impurities are blocked by the filter element, and the clean air flows out of the filter element. The following editor will give you a general introduction to the classification and characteristics of air filters.


1. The wire-wound filter element is refined by winding the textile fiber yarn with good filtering performance on the porous skeleton. The yarn materials include polypropylene fiber, acrylic fiber, absorbent cotton fiber and so on. By controlling the tightness and density of the yarn during winding, filter elements with different precisions can be made. Features: It can effectively remove suspended solids and particulate impurities in various liquids, and has a high purification effect on various liquids.


2. Folding filter element The folding microporous filter element is a precision filter device made of polypropylene thermal spray fiber membrane, nylon polytetrafluoroethylene microporous filter membrane and other filter media. It has the advantages of small size, large filtering area and high precision.


3. PP filter element PP filter element is also called PP melt-blown filter element. The melt-blown filter element is made of polypropylene ultra-fine fiber thermally entangled. The filter element fiber randomly forms a three-dimensional microporous structure in space, and the dimensional pore size is distributed along the filtrate flow direction. , Integrating surface, deep, and fine filtration, it can intercept impurities of different particle sizes. Features of PP cotton filter element: The accuracy range of the filter element is 0.5-100μm, and its flux is more than 1.5 times that of the peak room filter element of the same accuracy. Different types of end cap connectors can be configured to meet the needs of various engineering installations.
