Compressed air generated by air compressors contain inherent impurities that are detrimental to compressed air conveying and the end application. Some common contaminants of compressed air can be water, dirt, small wear particles, bacteria and sometimes even degraded lubricating oil. All these impurities mix together and often form an acidic sludge that might increase the wear and tear of end applications like pneumatic tools, machineries, valves orifices and electro pneumatic controls like relays etc.,
