Impurities in the oil can cause damage to the compression element's rotors and housing, resulting in reduced performance and higher operational costs. They can also harm the bearings, leading to rotor contact, possible element failure and production downtime. Finally, they shorten the lifetime of components and of the oil itself.
The oil filter captures dust, deposits and other foreign particles, ensuring a clean oil flow to the compressor element. Apart from protecting the bearings and other mechanical components, it prevents premature clogging of the air/oil separator.
