Compressed air is generated by a Compressor compressing ambient air. If impurities in the compressed air come into contact with the end product, this can lead to higher rejects. This often turns what at first glance appears to be a cost-effective solution into a very expensive way of generating compressed air. It is therefore essential for the user to treat the compressed air after it has been generated, as this air contains water, Oil, dust particles and other impurities. Depending on the required Compressed air quality, these ingredients can cause problems during production and increase operating costs.
