Compressed air is not pure. The compressed air contains inherent impurities that are detrimental to the end application. Some common contaminants of compressed air are water, dirt, small wear particles, bacteria, and sometimes even degraded lubricating oil. These impurities mix and often form an acidic sludge that might increase the wear and tear of end applications like pneumatic tools, machinery, valves orifices, and electro-pneumatic controls like relays. For increased reliability and energy savings, compressed air must be absolutely clean and dry.

ELGi offers a wide range of pneumatic downstream accessories that ensure application-specific air quality norms are met per the ISO 8573 standards. The air treatment downstream & condensate management solutions offered by ELGi are called AIRMATE systems, and energy conservation systems are classified as ELGi CONSERVE.
