What is the function of a purifier in fuel oil systems?

The main idea is that a purifier’s job is to remove both water and solid contaminants from fuel oil to improve combustion and engine reliability. Purifiers use centrifugal separation to throw the heavier water and sludge to the bottom while the cleaner fuel exits for use in the engine. This removes emulsified water and fine solids that can cause injector wear, clogged filters, and unstable combustion, all of which threaten engine performance and longevity. Removing water alone wouldn’t address solids that can cause wear, and purifiers aren’t just simple filters or meant to remove air from the fuel supply.
