Air supplied from compressors is used throughout the industry for various applications such as manufacturing, painting, shot blasting, vessel entry and air diving. When ambient air is compressed it becomes contaminated with oil, water vapour, particulates, and other gases such as carbon monoxide. Before the air is used for critical process purposes it has to be filtered and dried using specially designed purification units. The quality of the air has to be tested to validate the performance of the purification equipment and prove that the air is safe to use in the process in accordance with internationally accepted quality class standards as defined in ISO 8573. This course will provide a completely holistic approach to help companies manage the process performance risks associated with compressed air. Experience has shown that there is a great need for awareness generation. To facilitate education and awareness, we have developed a training course. The course has been designed to help employers and employees fully understand the potential risks associated with compressed air quality, the legislation, and air quality guidelines, methods of air purification, how to test compressed air quality, interpret results and maintain records. The vital importance of life cycle service and maintenance of the air purification equipment is also discussed and highlighted. This course has been delivered throughout the UK and internationally.
