The guide explains three key characteristics: compressed air is always wet, always contaminated, and composed of other gases. It details how liquid water, oil aerosols, dirt, microorganisms, trace gases, and unwanted oxidation/oxygen or inert nitrogen behaviors are formed, and how they damage equipment, increase costs, cause corrosion, ice buildup, micro-organism growth, and poor product quality. It also describes compressed air drying concepts such as saturation, condensation, dew point, and pressure dew point, and introduces adsorption dryers as a solution.",{"@graph":69,"@context":122},[70,84,105],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":30,"@type":76,"position":81},"https://docshare.wps.com/document/technology/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/adsorption-dryers-air-treatment-guide/652334/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/adsorption-dryers-air-treatment-guide/652334.png","ImageObject",300,407,{"name":92,"@type":93},"Hazel","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-28","2026-10-24",true,{"@type":102,"interactionType":103,"userInteractionCount":19},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"Why is air treatment necessary for compressed air?","Question",{"text":112,"@type":113},"Untreated compressed air contains contaminants due to how air is produced and compressed.

The need for air treatment basically results from 3 characteristics of compressed air.  \n4 | Adsorption dryers  \nCompressed air is always wet  \nContaminants  \n• Liquid water-water aerosols-water vapor  \nHow are the contaminants formed?  \nAs water is incompressible, the amount of moisture perm³ increases when air is compressed. The maximum amount of moisture per m³ air1 is however limited for a certain temperature. Condensation will thus be formed when air is compressed.  \nVapour  \n8 m3 ambient air  \n Compression  \nLiquid  \n1 m3 compressed air at 7 bar(e)  \nWhat problems can the contaminants cause?  \n• Corrosion of pipe lines  \n• Bad quality of the end product  \n• Malfunctioning of controls  \n• Build-up of ice  \n• Cultivation of micro-organisms  \nThe Pneumatech solution  \n• Water separators  \n• Drains  \n• Refrigeration dryers  \n• Adsorption dryers  \nCompressed air is always contaminated  \nContaminants  \n• Liquid oil-oil aerosols-oil vapor  \n• Dirt-microorganisms-pipescale  \n• Trace gases: carbon monoxide, sulfur dioxide, nitrous oxide  \nCompressed air composes of other gases  \nContaminants  \n• Oxygen: contaminant if oxidation is unwanted  \n• Nitrogen: contaminant if oxidation is wanted  \nHow are the contaminants formed?  \nAdded by the compressor installation through oil lubricated compressors (oil), adsorption dryers and activated carbon filters (dirt), piping network and vessels (pipescale) .  \nTrash in, trash out: oil vapors from car exhausts and industrial processes, atmospheric dirt and microorganisms get sucked in by the compressor. As with water, their concentration – and thus importance – increases significantly after compression.  \nHow are the contaminants formed?  \nDry air is mainly composed of nitrogen (78%) and oxygen (21%) . Air will keep the same nitrogen/oxygen ratio after compression, so additional treatment is needed to change this gas mix.  \nCarbon dioxide  \n0.03%  \nCO2  \nOther gases  \n0.01%  \nOther gases  \nNitrogen  \n78.08%  \nWhat problems can the contaminants cause?  \n• Damaged production equipment, leading to inefficiencies and increased costs  \n• Air pollution, creating unhealthy work environments  \n• Pollution of the condensate  \nThe Pneumatech solution  \n• Oil coalescing filters  \n• Oil vapor filters  \n• Particulate filters  \n• Oil-water separators  \n• Breathing air units  \nWhat problems can the contaminants cause?  \n• Oxygen causes oxidation, leading to explosions or fire of flammables (fast oxidation) or to rotting processes and corrosion of metals (slow oxidation) .  \n• Nitrogen is an inert gas that can prevent oxidation to happen.  \nThe Pneumatech solution  \n• PSA nitrogen generators  \n• Membrane nitrogen generators  \n• PSA oxygen generators  \nAdsorption dryers | 5  \nCompressed Air Drying  \nMoisture is a fundamental element of atmospheric air, where it is present in the form of water vapor. The maximum moisture holding capacity of air (the maximum amount of moisture air can hold per m³ / ft³) is limited for a certain temperature; and increases as the temperature increases. At and above this line the air is 100% saturated (relative humidity of 100%), meaning that the excess moisture will condense as liquid water, and will in cold environments even transform to ice.  \n6 | Adsorption dryers  \nAs it is not possible to compress water, the moisture content of compressed air increases in relation to the pressure of the compressed air. As a result the moisture content will exceed the maximum moisture holding capacity of air (which is only dependent on temperature) and the excess amount of moisture will condense into ","cbCail8z8fKMGkAP","https://ap.wps.com/l/cbCail8z8fKMGkAP","pdf",723970,24,"English","# Air treatment guide\n## Compressed Air Treatment\n## Compressed Air Drying\n## Types of compressed air dryers\n## Operating Principle\n## Features and benefits explained\n## Compressed Air Purity","[{\"question\":\"Why is air treatment necessary for compressed air?\",\"answer\":\"Untreated compressed air contains contaminants due to how air is produced and compressed.
