THE AMSOIL Ea SPIN-ON BY-PASS OIL FILTER

  • Absolute Protection from Engine Dirt
  • Assurance of Analytically Clean Oil

WHY ANOTHER FILTER?  Even the best full flow-filter can't do it all.

Any full flow filter must allow oil to pass through it quickly to keep the engine from starving for oil.  Advances in auto technology and more compact engine designs place increasing demands on these filters; to keep from creating a circulation bottleneck they filter out only the coarser particles, and feature relief valves that open when the engines demand for lubrication can't be ignored.

But the smallest grit that passes through-   road dust, manufacturing scarf, and engine metal-flake in the 5- to 20-micron range - accounts for up to 60% of all engine wear.  These microscopic particles closely match the precision clearances between critical engine components; they can enter the spaces between bearings, rings, and other components, to damage metal surfaces, altering tolerances, fatiguing components and generating additional debris.

Automobile engines are also susceptible to damage related to water formation, something a full flow filter is powerless against.  Water enters the oil either as blowby combustion product of fuel ignition, or as condensed moisture from air drawn into the engine through the air intake.  Water causes metal surfaces to rust; it also reacts with other blowby contaminants to produce corrosive acids that attack the engine, contributing to further friction, wear, debris, and oil degradation.

The AMSOIL Solution-  By-Pass Filtration

Unlike a full-flow filter, the AMSOIL Ea By-Pass Filter is situated outside of the main line of oil circulation; it taps into the line to bleed off and clean only a portion of the oil at a time.  The AMSOIL Ea By-Pass Filter retains the oil longer and does a more thorough job of removing contaminants without obstructing flow.  You still need a full-flow filter, of course, because oil must circulate continuously. But with an AMSOIL Ea By-Pass Filter drawing 10% of your system's capacity, all the oil in a six-quart system will be filtered to analytical purity in about  five minutes, at an average engine speed equivalent to 45 mph.

The differences between the AMSOIL Ea By-Pass Filters and others are the unique design of the filtering media and the patented construction of the filter element.  Our high-capacity filtration medium is a special blend of virgin wood and cotton fibers formed into disc, stacked, and compressed.  The center tube is all-steel, perforated for oil flow and wrapped with a fine mesh cotton screen.  All dirt particles down to one-tenth of a micron in size are trapped, and the medium's thirsty cellulose fibers can remove up to a pint of water.  Channeling is eliminated  with the inclusion of a hydraulic follower plate activated by a sophisticated internal pressure system. 

 
 
Ea Spin-On By-Pass Filters
AMSOIL Ea Spin-On By-Pass Filters offer the ultimate in filtration technology. Engine wear is caused by dirt particles larger than 5 microns. The AMSOILEa By-Pass Oil Filter removes particles less than 1 micron, virtually eliminating engine wear. AMSOIL Ea By-Pass Oil Filters filter all the oil in a six-quart system in about five minutes at an average engine speed equivalent to 45 mph

Heavy-Duty By-Pass Filtration System

In May, AMSOIL unveiled its new by-pass filtration mounts, which included a number of improvements to an already superior product, such as better oil flow and more durable spin-on adapters. Now, AMSOIL also offers the same technology for heavy-duty applications. The new AMSOIL Heavy-Duty By-Pass Filtration System (BMK30) and Heavy-Duty Ea By-Pass Filter (EaBP120) offer maximum by-pass filtration performance for heavy-duty applications.

AMSOIL BMK30
The BMK30 is made from high-quality cast aluminum with a steel filter spud that has been thoroughly tested in on-road and severe off-road service. The mount is finished with a thick layer of powdercoated paint to provide maximum resistance to the degrading effects of road salt, debris and engine compartment chemicals. In addition, BMK30 By-Pass Filtration Systems can be plumbed in a series to provide maximum filtration protection for large V12 and V16 engines. The filter mount features a 3?8" NPT connector that connects the outlet and inlet of adjacent filter mounts. For more information on engine adapters or the installation of multiple by-pass systems on one application, contact AMSOIL Technical Services at (715) 399-TECH.

 
Heavy-Duty By-Pass Filtration System
For heavy-duty by-pass applications. Featuring the same synthetic nanofiber media as the rest of the Ea By-Pass Filter family. Filter and hose not included with the BMK30 kit. The EaBP120 Filter and hose (BP250) must be purchased separately.

The AMSOIL Ea Dual-Remote Oil Filtration System
For Optimum OIL FILTRATION and Maximum SERVICE ACCESSIBILITY

The AMSOIL Ea Dual Remote Oil Filtration System replaces the standard full-flow system with a combination full-flow/by-pass system using a remote mounting assembly.

The mount couples an AMSOIL Ea Oil Filter with an AMSOIL Ea Spin-On By-Pass Filter; it takes oil from the engine and returns it without the use of multiple fittings or extra return holes in the oil pan or valve cover.  The mount and filters are installed in an accessible area of the engine compartment.

A specially-manufactured, spin-on casting with threading adapters is simply screwed onto the engine block's filter nipple, replacing the old full-flow filter.  In-and-out ports in the casting and two flexible oil lines connect this adapter to the remote mount.

Remote placement of the filtration units allows larger oil filters to be used, and increases sump capacity - dramatically extending the oil's useful service life and protecting your wise investment in AMSOIL Synthetic Motor Oil.  The recommended replacement interval for the AMSOIL Ea By-Pass Oil Filter is 25,000 miles or one year (whichever comes first).

 
AMSOIL Ea Dual Remote Oil Filtration System
The AMSOIL Ea By-Pass Oil Filter provides the best possible filtration protection against wear, oil degradation, rust and corrosion. Working in conjunction with the engine's full-flow oil filter, the AMSOIL Ea By-Pass Filter operates by filtering oil on a "partial-flow" basis. It draws approximately ten percent of the oil at any one time and traps the extremely small, wear-causing contaminants and water that full-flow filters can't remove. The AMSOIL Ea By-Pass Filter typically filters all the oil in the system several times an hour, so the engine continuously receives analytically clean oil.

AMSOIL Ea Marine Dual Remote Oil Filtration System

The AMSOIL Ea Dual Remote and By-Pass filtration systems have been an integral part of the company's advanced engine protection product line. Building on the customer-proven success of automotive dual remote and by-pass filtration technology, the Marine Dual Remote Filtration System was created to address the specific severe operating environment of marine engines in both salt and fresh water. For example the hose fittings are coated with a 3 ml layer of AlumiplateT and 1 ml of zinc and yellow chromate. Standard hydraulic fittings typically survive for 96 hours in the grueling ASTM B-117 Salt Spray Test. When we subjected the AlumiplateT coated AMSOIL Ea Marine Bypass System fittings to this critical corrosion resistance test protocol, they lasted over 1,000 hours! This means the AlumiplateT coating on the fittings of the AMSOIL Ea Marine Bypass Filtration System are 10 times more corrosion resistant than standard zinc and yellow chromate plated fittings. While this exclusive AlumiplateT coating process is expensive, AMSOIL felt this extra margin of system protection was absolutely necessary to provide marine application customers with extraordinary corrosion resistance and protection - and the peace of mind that goes with knowing that the AMSOIL Ea Marine Bypass System is engineered for demanding marine applications. Also, the fasteners and mounting bracket are stainless steel, and the hose are U.S. Coast Guard approved.

Ea Dual-Gard Oil Filtration System

AMSOIL took the performance built into our standard big truck By-Pass filters, and put it into a much more convenient and versatile pacakge.

Proof From the Test Labs

Wear tests have shown particles of contamination in the sub-20-micron range are most harmful to rings and bearings. Most trucks are sold with a full-flow filter as their only oil cleasnsing unit. A study by the Milwaukee School of Engineering determined the filtering efficiency of four top-selling full-flow filters compared with a BE-90 AMSOIL Ea Spin-On Bypass Filter. The graph (below) shows the By-Pass functioning at 97.6% efficiency in removing particles as small as 3 microns, a feat no full-flow filter can match.
