What is the primary function of the purifier?

The primary function of the purifier is to remove water from oil through the process known as stripping. In many engineering applications, especially in the context of fuel and lubricating oil systems, it is essential to maintain the quality of the oil by eliminating impurities such as water. Water in oil can lead to corrosion, reduced lubrication properties, and other operational issues.

Purifiers typically work by utilizing centrifugal force to separate contaminants from the oil, allowing for effective separation of water and other particulates. This process is vital in ensuring that the oil maintains its optimal performance characteristics and extends its service life. By removing water, the purifier helps maintain the integrity and efficiency of systems that rely on oil, thus supporting overall operational reliability. Other options, while relevant to oil management in some context, do not capture the essential function of the purifier as effectively as the removal of water.
