Air lubricators are responsible for ensuring proper operations of moving parts and contrivances. Oiling reduces friction of sliding parts, thus providing an increase in efficiency and reducing damage caused by constant interaction of parts. Providing sufficient lubing prolongs the life cycles of components, and reduces the need for regular maintenance. In terms of supplying oil into the systems more doesn't mean better. Excessive lubricating can clog up the system and be simply wasteful, while insufficient lubrication may seriously affect the performance and the state of internal mechanisms.
