Air quality and life of a dry compressor
The life of dry compressors
The life of dry compressors has always been thought to be shorter than the life of lubricated compressors. This sounds like an evident truth: the oil fills empty spaces, dampens noise, reduces wear and the temperature of rubbing surfaces. However Cattani can now demonstrate that the opposite is true: it is just a matter of material selection and accurate workmanship. The compatibility of rubbing materials (also defined as self-lubricating) and accurate workmanship eliminate the wear of rubbing parts even without lubrication.
Cattani have tested their pistons for up to 10,000 hours without reporting any size reduction; we have received compressors for servicing which had worked for 25 years without any considerable wear. No wear means preserving compressed air from contamination. This kind of results require careful research and commitment supported by a special passion.
