COMPRESSED AIR IS NOT WITHOUT IT’S PROBLEMS, WITH ALL SYSTEMS SUFFERING FROM PERFORMANCE AND RELIABILITY ISSUES. ALMOST ALL OF THESE CAN BE DIRECTLY ATTRIBUTED TO CONTAMINATION, THE MAIN SOURCES OF WHICH ARE : There are 10 major contaminants found in a compressed air system, these are: Contaminant removal Failure to remove this contamination can cause numerous problems in the compressed air system, such as: • Corrosion within storage vessels and the distribution system • Blocked or frozen valves, cylinders, air motors and tools • Damaged production equipment • Premature unplanned desiccant changes for adsorption dryers In addition to problems associated with the compressed air system itself, allowing contamination such as water, particulate, oil and micro-organisms to exhaust from valves, cylinders, air motors and tools, can lead to an unhealthy working environment with the potential for personal injury, staff absences and financial compensation claims. Compressed air contamination will ultimately lead to: • Inefficient production processes • Spoiled, damaged or reworked products • Reduced production efficiency • Increase manufacturing costs Purification Equipment Technologies Bulk Condensed Water Water Vapour Water Aerosols Atmospheric Dirt & Solid Particulate Micro-organisms Oil Vapour Liquid Oil & Oil Aerosols Rust & Pipescale Water Separator 3 7 7 7 7 7 7 7 Coalescing Filter 7 7 3 3 3 7 3 3 Adsorption Filter 7 7 7 7 7 3 7 7 Adsorption Dryer 7 3 7 7 7 7 7 7 Refrigeration Dryer 7 3 7 7 7 7 7 7 Dust Removal Filter 7 7 7 3 3 7 7 3 Microbiological Filter 7 7 7 3 3 7 7 7 CONTAMINANTS The largest quantity of contamination introduced into the compressed air system originates from the atmospheric air drawn into the compressor and not as often believed, introduced by the compressor itself. The most prolific and problematic of the contaminants is water which accounts for 99.9% of the total liquid contamination found in a compressed air system. High efficiency compressed air filtration is not only used to remove particulate and oil, but more importantly it removes water aerosols and is key to operating an efficient and cost effective compressed air system. Regardless of what type of compressor is installed, the same level of filtration is required. The table below highlights each of the purification technologies required to remove the different contaminants present in the compressed air system. • THE AMBIENT AIR BEING DRAWN INTO THE COMPRESSOR • THE TYPE AND OPERATION OF THE AIR COMPRESSOR • Atmospheric Dirt • Rust • Pipescale • Liquid Oil • Oil Aerosols • Oil Vapour • Water Vapour • Condensed Water • Water Aerosols • Micro-organisms • COMPRESSED AIR STORAGE VESSELS • DISTRIBUTION PIPEWORK Purification Equipment Technologies Bulk Condensed Water Water Vapour Water Aerosols Atmospheric Dirt & Solid Particulate Micro-organisms Oil Vapour Liquid Oil & Oil Aerosols Rust & Pipescale Water Separator 3 7 7 7 7 7 7 7 Coalescing Filter 7 7 3 3 3 7 3 3 Adsorption Filter 7 7 7 7 7 3 7 7 Adsorption Dryer 7 3 7 7 7 7 7 7 Refrigeration Dryer 7 3 7 7 7 7 7 7 Dust Removal Filter 7 7 7 3 3 7 7 3 Microbiological Filter 7 7 7 3 3 7 7 7 CONTAMINANTS The largest quantity of contamination introduced into the compressed air system originates from the atmospheric air drawn into the compressor and not as often believed, introduced by the compressor itself.

COMPRESSED AIR PURIFICATION EQUIPMENT IS ESSENTIAL TO ALL MODERN PRODUCTION FACILITIES. IT MUST DELIVER UNCOMPROMISING PERFORMANCE AND RELIABILITY WHILST PROVIDING THE RIGHT BALANCE OF AIR QUALITY WITH THE LOWEST COST OF OPERATION. TODAY, MANY MANUFACTURERS OFFER PRODUCTS FOR THE FILTRATION AND PURIFICATION OF CONTAMINATED COMPRESSED AIR, WHICH ARE OFTEN SELECTED ONLY UPON THEIR INITIAL PURCHASE COST, WITH LITTLE OR NO REGARD FOR THE AIR QUALITY THEY PROVIDE OR THE COST OF OPERATION THROUGHOUT THEIR LIFE. WHEN PURCHASING PURIFICATION EQUIPMENT, THE DELIVERED AIR QUALITY, COST OF OPERATION AND THE OVERALL COST OF OWNERSHIP MUST ALWAYS BE CONSIDERED. ...
