Excuse me, the experience range of dust particles in grade 100 and grade 10000 clean areas in the sterile API workshop ~ Level 100 and level 10000 are 0 according to the US standard.The number of dust in 5um is below 100 and 10000.The 100000-grade polymer material factory I have handled,The number measured in the workshop is nearly 70000;Circuit board factory of grade 10000,The number I measured at many measurement points is generally 3000-4000 or so,There are nearly 7000 locations.We use the dust particle counter produced in Jiangsu,The results of the measurement are a little different from the data measured by other detectors in the factory,But the impact is not big.Boss,You are a pharmaceutical factory;New norms must be followed.First, correct it,There is no saying of level 100 and level 10000 now;Only A \ B \ C \ D.Standards for dust particles,Also in the new GB;Haven't you bought the medicine factory yet?Two, as for the scan you said,This has something to do with the device you use.Look at the equipmen
What are the standards when using compressed air filters in power plants? Compressed air is an important gas source, which is widely used in purge parts, thermal pneumatic instruments, thermal protection devices and actuators by power plants.Requirements of air equipment for power plant for compressed air qualityAccording to the provisions of GB/T13277-91 'general compressed air quality grade', compressed air quality shall meet the following requirements:1. the dew point of the working pressure is-40 ℃;2. the dust-containing particle size of the purified gas is not greater than 1um, and the maximum mass concentration is not greater than 1 mg/m3How can this be met? Of course, compressed air precision filters and drying equipment are used.Choice of precision filter for compressed air of power plant:Dpc recommends that the particle size of the gas containing dust should not be greater than 1um, and the maximum mass concentration should not be greater than 1 mg/m3.
