Catalog 0722-E Air Preparation Systems Warning, Offer of Sale ! CAUTION: Polycarbonate bowls, being transparent and tough, are ideal for use with Filters and Lubricators. They are suitable for use in normal industrial environments, but should not be located in areas where they could be subjected to direct sunlight, an impact blow, nor temperatures outside of the rated range. As with most plastics, some chemicals can cause damage. Polycarbonate bowls should not be exposed to chlorinated hydro-carbons, ketones, esters and certain alcohols. They should not be used in air systems where compressors...

Compressed air and its purification from generation to application Compressed air is an essential power source that is widely used throughout industry. This safe, powerful and reliable utility can be the most important part of your production process. However, your compressed air will contain water, dirt, wear particles and even degraded lubricating oil which all mix together to form an unwanted condensate. This condensate often acidic, rapidly wears tools and pneumatic machinery, blocks valves and orifices causing high maintenance and costly air leaks. It also corrodes piping systems and can...

Types of contamination found in a compressed air system Atmospheric dirt Atmospheric air in an industrial environment typically contains 183 million per yd3 (140 million per m3) of dirt particles. 80% of these particles are less than 2 microns in size and are too small to be captured by the compressor intake filter, therefore passing directly into the compressed air Water vapor, condensed water and water Atmospheric air contains water vapor (water in a gaseous form). The ability of compressed air to hold water vapor is dependent upon it's temperature. The higher the temperature, the more water...

Up to 99% of the total liquid contamination found in a compressed air system is water. Oil is perceived to cause the most problems as it is seen emanating from open drain points and exhausting valves, however, in the majority of instances, it is actually oily condensate (oil mixed with water) that is being observed. How much water can be found in a typical compressed The amount of water in a compressed air system is staggering. A small 100 SCFM (2.8m3/min) compressor and refrigeration dryer combination, operating for 4,000 hours in typical climatic conditions can produce approximately 2,200 gallons...

Purification Technologies Having identified the different types of contamination that can be found within a compressed air system, we can now examine the purification technologies available for it's Particle and coalescing filters Coalescing filters are probably the most important items of purification equipment in any compressed air system. They are designed to remove oil and water aerosols using mechanical filtration techniques and have the additional benefit of removing solid particulate to very low levels (as small as 0.01 micron in size). Installed in pairs, most users believe one to be...

catalog 0722-E Air Preparation Systems Quality Standards Compressed air quality standards - ISO 8573 standards relating to the quality of compressed air and consists of nine separate parts. Part 1 specifies the quality requirements of the compressed air and parts 2-9 specify the methods of testing for a range of contaminants. document used from the ISO 8573 series and it is this document which allows the user to specify the air quality or purity required at key points in a IS08573-1 lists the main contaminants as Solid Particulate, Water and oil. The purity levels for each contaminant are shown...

PDRD Series What is refrigeration drying? The use of refrigeration drying for compressed air treatment is tested and proven for many industrial applications. Dewpoints of 35°F (1.7°C) to 50°F (10°C) are suitable for many indoor applications where a general removal of bulk water and some vapor is sufficient for the end user's process. Refrigeration dryers use a set of heat exchangers or a single heat exchanger (with chambers) first to pre-cool the air; second, to refrigerate the airto condense out moisture vapor; and last, to re-heat the air to prevent pipe sweating downstream. Direct Expansion...

PlusPack heat exchanger (patent pending) The revolutionary PlusPack features a 3-in-1 aluminum design with integral air connections. All models include an air-to-air freecooler, while the unique "slowflow" demister ensures perfect dewpoints whatever the operating Demister separator A high capacity demister separator is employed for the removal of condensed liquids. This lowers the air velocity which maximizes the condensate separation from the air, even when the dryer is not operating at maximum flow. This design also ensures the differential pressure across the dryer Refrigerant condenser Oversized...
