What does the test of media migration in the filter mean? High efficiency air filter (HEPA filter) is widely used in rooms that require cleaning and sterility (manufacturing sites for electronic products and medicines, operating rooms) and other applications such as air purifiers, vacuum bag dust collectors and masks ).All kinds of media such as ultra-fine glass fiber mat, melt spray (MB) fiber mesh, electrostatic spinning fiber mesh and ePTFE film can meet the filtration requirements of HEPA.The filter medium is made of microfiber or microfiber,Or have a fiber structure,In order to have a large fiber surface area or there are many pores in the original fiber structure.The surface density, dust collection and service life of the filter media are different,Materials with different components and structures have different pressure drops.Compared with sub-micron microfiber and nano-fiber electrostatic spinning mesh,The diameter of the microfiber mesh is thicker,It is necessary to go through resident polarization

The air compressor has a filter. how can it be sprayed with water? I don't know what filter you are talking about.In general, air compressors have air filters, oil filters, oil and gas separatorsThe air filter mainly filters the solid dust in the air before inhaling, usually between 5-20 μm,The oil filter mainly filters the lubricating oil before entering the fuel injection port after the cooler (heat exchanger), mainly filtering the solid impurities in the lubricating oil, such as metal debris, etc.The oil and gas separator mainly separates the oil and gas mixture before the outlet, separating more than 99% of the liquid lubricating oil from the compressed air into the lubrication system for repeated recycling.Filters outside the air compressor are generally called post-processing equipment, with air-water separators, filters of various accuracy grades, and some special filters such as deodorization filters and oil removal filters.There is also condensed water in the compressed air, because the conte
