700% INCREASE IN COMPONENT LIFE
Sayles and MacPherson conducted a study to determine the life of bearings, a common and important component in all automotive, aeronautical and industrial machinery. Your engine and transmission consist of hundreds of similar bearings or components to those tested. The results of their study showed that the approximate thickness of the oil in the bearings was 3-10 microns. It also showed that most filtration was only at levels of 40 micron, like your transmission or engine spin-on filters. BUT if you could filter the oil of contaminants down from 40 microns to 3 microns there was a seven-fold increase in the life of the component.
EXTENDS PUMP LIFE BY 50 TIMES
Oklahoma State university reported in their study that when fluid is maintained 10 times cleaner, hydraulic pump life can be extended by 50 times. Most vehicles have a power steering pump and some have additional pumps powering other hydraulic applications, all of which are subject to failure from the small iron particles circulating in the fluid.
70% REDUCTION IN WEAR
AC Delco Division of General Motors also tested DDA [Detroit Diesel Allison] engines and found an eight-fold improvement in wear rates and engine life with lower lube oil contaminant levels. In a related study on both diesel and automotive engines, General Motors reported that "... compared to a 40-micron filter, engine wear was reduced by 50% with 30 micron filtration. Likewise, wear was reduced by 70% with 15 micron filtration."
OVER 50% OF CONTAMINANTS IN TRANSMISSIONS ARE WEAR-HARDENED IRON
Levels of Metal Contamination
The study also showed that over 97% (by number) were less than 10
microns in size.
COMMON CAUSES OF FAILURE
Three types of contaminant related failures have dominated the problems
found. These are failures due to locking and or seizure [termed contaminant
sensitivity] due to small particles (below 50 microns); durability failures
due to the whole distribution of particles over a long time (termed contaminant
wear); and catastrophic failure due to the jamming of large particles
in metering devices (termed contaminant jamming). It must be remembered
that these valve tests were on fluid that had already passed through the
sump filter in the transmission before they had caused catastrophic and
other failure modes.
Laboratory and field tests have shown that the most damaging metal particles are the ones that jam within the thin film of oil that cushions vital parts
Laboratory tests have proven the benefits of magnetic filtration
