Available at parker.com/gsfe Simple guidelines for the selection of purification equipment 1. Purification equipment is installed to provide air quality, therefore you must first of all identify the quality of compressed air required for the compressed air leaving the compressor room and for each point of use on the compressed air system. 2. The air quality required at each point of use may differ dependent upon the application. 3. Using the quality classifications shown in ISO8573-1 will allow easy selection of purification equipment. 4. ISO8573-1:2010 is the latest edition of the standard, however some facilities may still be operating on older revisions. 5. Specifying air quality as ISO8573-1, ISO8573-1:1991 or ISO8573-1:2001 refers to the previous editions of the standard and may result in a different quality of delivered compressed air. 6. Ensure any ISO8573-1 air purity classifications are written in full and include the revision year to allow for correct product selection. 7. Remember - Oil-free compressor installations require the same filtration considerations as oil lubricated compressor installations.
