What are the specifications of the intermediate filters for each filter accuracy, the air volume per unit area, or the air flow speed, and how to calculate the pressure loss? There are also some so-called national standard specifications: 484*484 *?Generally, there are some detailed requirements,The amount of ventilation is related to the flow rate,Generally, one Shanghai index is required,Loss of pressure,The initial pressure is generally 200,The end pressure is not big,There are also hundreds of Pa, which have national standards,
Where is the KLC filter produced-what are the KLC efficient filter detection methods? KLC filter manufacturers can enter in Baidu: KLCFILTER's first website is!From Britain,China,Some European countries in the 20 th century 70 ~ Implemented in 1990s.The source of the test dust is sodium chloride salt spray.'Quantity' is the brightness of the hydrogen flame when it contains salt spray.The main instrument is the spectrometer.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.The average diameter of salt spray particles stipulated by the national standard is 0.4mm,However, the measured results of the existing domestic devices are 0.5mm.The measurement results of the actu
