What are the test methods for efficient filters ??? From Britain,China,Some countries in Europe 70-Implemented in 1990s.The source of the test dust is sodium chloride salt spray.'Quantity' is the light intensity of the hydrogen flame characteristic light when it contains salt spray.The main test instrument is a luminosity meter.Salt water splashed under the stirring of compressed air,Dry to form a tiny salt spray and enter the air duct.Sampling before and after the filter,The salt mist samples blue and increase the brightness of the hydrogen flame.Judging the salt spray concentration of air by flame brightness,And then determine the filter efficiency of the filter for salt spray.Relevant standards: GB6165-in China-85,At present, relevant domestic departments are revising the standard,Whether to abolish or continue to be inconclusive.The method is no longer used in Europe.Original West Germany,The Soviet Union,And China has adopted this method.The source of dust is oil mist.The 'quan

Working Principle of compressed air filter Introduction: Compressed air filter may not be understood by many people in daily life,Not a professional will certainly not know much about compressed air filters.Today, let's learn how the compressed air filter works.1. the Air generally contains harmful substances such as dust, rust and moisture,Compress these air with harmful substances into the first set of filtration devices for compressed air or filters.Compressed air will have a agglomeration effect when the first filter device is used,That is, when you pass this channel, you will condense some particles,The larger particles will remain on the filter,Because the particles are large, they are adsorbed by the filter material,After these small particles are condensed for a long time, the water will become a relatively large water drop.2. the compressed air will enter the separation room after that,The flow of air will naturally slow down after entering the separation chamber,When the flow of air slows dow
