BEAR TRAP
MAGNETIC FILTERS™
Dirt and wear contaminants your oil filter cannot capture are damaging your engine and costing you unnecessary oil changes.
Dirty Secrets - Where do Abrasive Wear Particles Come From?
1. The refining process does not filter engine oil to below 10 microns.
2. Up to 18% of the old oil remains in the engine during an oil change.* Particles suspended in the oil stick to the surfaces of your engine.
3. Particles less than 10 microns generate about 3.5 times more engine wear than particles greater than 10 microns in size** .
4. Washing fluids used to clean new engine components in the manufacturing process are not filtered to sub 10 micron levels. This leaves abrasive residue. Additional residue is generated during the engine "break in"period.
5. Contaminants such as silica enter the engine through the engine air filtration system. Gasoline and diesel also bring wear particles from the refinery, pipelines , trucks and storage tanks. Diesel deposits soot in the engine.
6. Even premium oil filters do not capture particles below 20 microns in size.
7. Two percent of the weight of oil circulated is dirt particulate*. This means that over 2 tons of abrasive solids circulate through an average car engine running 12,000 miles (19,440 km) per year!

UNDER LOAD
Oil Analysis - 2002 Kenworth - CAT 3406 475hp Engine with 1.054 million miles (1.7 million km).
Randy O'Linyk, of Calgary, AB uses magnetic filters on his engine oil, coolant and fuel. Over a 12 year period he extended his oil change interval from the recommended 300 hours to 700 hours. Using an average speed of 40 mph, the 12,000 mile oil change interval was stretched to 28,000 miles. (over 45,000 km). The engine oil analysis on the right shows the oil condition is excellent, even at 744 hours, or an estimated 29,760 miles.

How Bear Trap™ Magnetic Filters Extend Oil, Filter and Engine Life.
The Bear Trap™ employs powerful, highest quality rare earth magnets in a configuration that penetrates deeply into the filter to trap and hold even sub-micron particles as shown below.
Studies conducted by a large manufacturer of heavy trucks using sub micron filtration concluded that a filter that can filter under 1 micron results in an 80% reduction in wear on compression rings.**

Why do over 200 companies in 37
countries trust Magnetic Filters?
After years of testing, the world's largest mining equipment now use magnetic filtration to double and triple maintenance intervals and double equipment life. Hydraulic fluid, engine and gear oils, transmission fluid, diesel, coolant and even grease are magnetically filtered.
Pipelines, refineries, petrochemical, ship loading, offshore platform and manufacturing facilities around the world rely on solutions from a sister company, Black Powder Solutions. Magnetic filtration systems extend the life and maintenance interval of pumps, seals and compressors by up to 2-3 times.
