Air quality

Air quality High quality compressed air reduces the need of maintenance, increases operating reliability of the pneumatic system, control system and instrumentation at the same time as wear to the air-powered machines is reduced. If the compressed air system is adapted for dry compressed air from the outset the installation will be less expensive and simpler, as the pipe system does not need to be fitted with a water separator and so-called, swan-necks. When the air is dry it is not necessary to discharge air to the atmosphere to remove condensation. Condensation drainage on the pipe system is also not required, which means lower costs for installation and maintenance. The best economy can be gained by installing a central compressed air dryer. Decentralizing air treatment, with several smaller units placed in the system, is more expensive and makes the system harder to maintain. It is normally calculated that the reduced installation and maintenance costs for a system with dry compressed air cover the cost of the drying equipment. Profitability is very good, even when it is a question of supplementing existing installations with drying equipment. Oil-free compressors do not need an oil separator or cleaning equipment for condensation. At the same time filters are not needed and therefore the cost for filter replacement is avoided. Consequently, there is no need to compensate for the pressure drop in the filter so compressor?s working pressure can be lowered, which improves the installation?s economy yet further.
