- One Micron Polishing Filtration
- Decrease Engine Wear
AXIAL FLOW DEPTH ROLL FILTERS
Engine oil doesn’t wear out, it just gets dirty. The longer it is kept uncontaminated, the longer time between changes. With Hoff Engineering’s axial flow depth roll filters, the intervals between oil changes can be safely maximized while reducing engine wear, costs, and the environmental impact.
Standard oil filters are full flow, designed to filter 100% of an engine’s oil in a single pass. Usually rated at 25 microns, they pass large volumes of oil at high flow rates. But, it is the fine particles (generally 1-15 micron, often soot and carbon deposits) that generate the majority of the contamination associated with engine wear. This contaminated oil gradually increases particle build-up, sludge deposits, mechanical wear, oxidation, and additive depletion.
Hoff Engineering’s axial flow depth roll filters polish small volumes of oil at slow flow rates, down to one micron. As a bypass filter, they can be plumbed onto virtually any engine. Any pressure point at the filter head or the pressure switch, or along the oil gallery can be accessed. Installation of auxiliary systems, such as the “Generation 2” LP Series, can incorporate these bypass filters without affecting overall engine oil flow or pressure. As long as the engine is running, they continually remove the fine particle contamination missed by standard full flow filters.
Full flow filters also do not efficiently remove the water produced in normal engine combustion. This water causes acid formation in the engine’s oil, which accelerates the depletion of the additives, which, in turn, accelerates corrosive action inside the engine. Hoff Engineering’s axial flow depth roll filters remove the water missed by standard full-flow filters. Their ability to constantly remove water makes for a virtually acid free engine. The result is a reduction in the breakdown of additives and a decrease in the related corrosive action. Bottom line: fewer oil changes and a better running engine.
To sum up the benefits of these one micron polishing filters:
- Prolongs the oil’s service life
- Minimizes wear
- Reduces close-in costs: waste oil disposal, downtime, purchase of new replacement full flow filters
- Helps create an acid-free environment which significantly slows the additives’ breakdown cycle
