Air filterCompressed air is a kind of very important energy source in modern industry, but under most of conditions, the original compressed air source cannot meet our normal produce, as inside contained many kinds of impurity. For example, besides water content, there are corrosive content like carbon-hydrogen component and solid particles (one hundred and forty millions particles per cubic meter) in the atmosphere. After processing by the compressor filter, these mixed air will be input into air compressor to get compressed, which will reduce the quality of compressor's lubricating oil and lead to part of oil become oil vapor to go into air pipe directly. Because of the effect of high-temperature and oxidation caused during compressing air, the mixed compressed air will become acidic with much high corrosive capacity. If it was inputted into air pipe, it will rust the pipe and pneumatic element greatly to cause malfunction, reduce the finish product's quality and increase the maintenance cost. ------------------------------------------------------------http://www.chinariway.com/Auxiliary_Equipment/Auxiliary_Equipment_Air_filter_AF001.asp-----------------------------------------------------
