Bypass Oil Filters

How Bypass Filters Works

Bypass oil filters function as a secondary filtration with the purpose of eliminating soot and small particle contaminants from motor oil. AMSOIL filter elements offer high holding capacities with a service life of one to two years, continuously removing soot and other particles too small for the full-flow filter. Continuously clean engine oil means oil lasts longer in service and engines remain in like new condition longer. Bypass filters work with a higher flow restriction to returning analytically clean oil to the engine and work in conjunction with a full-flow filter.

AMSOIL Bypass Oil Filter

Bypass filters operate by filtering oil on a “partial-flow” basis. They draw approximately 10 percent of the oil pump capacity for collecting the extremely small contaminants which are too small for the full-flow filter. Bypass filters have a high pressure differential, causing the oil to filter very slowly allowing for the removal of soot and small particle contaminants. It is called bypass filtration because the oil flows from the engine oil pressure to bypass filter and back to the sump, temporarily bypassing the engine. This continual process eventually cleans the entire oil system making it analytically clean with an absolute efficiency of 98.7 percent at two microns.

Bypass Filters Provide Three Basic Functions

  • Remove smaller particle contaminants beyond the ability of the full-flow filter
  • Higher filtration efficiency, contaminants remain trapped in the bypass filter
  • Element is able to remain in service for extended time or mileage

Bypass Oil Filter

Engineered for Outstanding Oil Filtration Efficiency

Higher Efficiency

AMSOIL Bypass Filters have an absolute efficiency of 98.7 percent at two microns. This highly efficient filter provides exceptional filtration performance, removing all the particles known to reduce engine life.

Superior Construction

AMSOIL Bypass Filters have a marine powder-coated exterior and an anti-corrosion coated base plate to provide excellent corrosion protection. AMSOIL Bypass Filters feature a nitrile HNBR gasket, an orange silicone anti-drain valve and proprietary high-efficiency media

Soot Removal

AMSOIL has designed a high-efficiency bypass filter element that is also a soot removal device. AMSOIL Bypass Filters use proprietary high-efficiency media. This media removes soot particles two microns and larger, eliminating abrasive wear from soot agglomeration.

Increased Oil Capacity

The increased fluid system capacity and filtration life provides improved oil cooling and ensures that equipment constantly runs on highly filtered oil. Engine efficiency is increased, providing extended engine life.

The primary benefits of an AMSOIL Bypass Filter System is to reduce mechanical wear, remove soot, control cylinder deposits and reduce lubricant replacement cost. Adding a bypass oil filter is a simple and most effective solution to keep any brand of engine oil clean. Clean oil can not only remain in service longer but also maintain engine efficiency and performance.
