Contamination Control Systems
How Small is “Small”
Contamination Control Systems
Reporting Cleanliness Levels
• Convenient format for reporting particle count data – Graph of particle size vs. particle concentration
• Simplified coding • Focuses on three particle size ranges:
– Total number of particles > 4µm
– Total number of particles > 6µm
– Total number of particles >14µm
ISO Cleanliness Code 4406:99

How do we measure fluid contamination?
Structure of ISO-Code: amount of dirt particles in a 100 ml sample larger than these specified sizes: 4µm / 6µm / 14µm / 21µm
Example: larger than 4µm = 2,234,000
ISO Code = / / /

How does this show a 50% improvement in engine life?
• Before is ISO Particle count given by oil analysis on vehicle not equipped with FilterMag
• After is ISO Particle count from FilterMag equipped vehicle
• Green Box shows results from the change in particle levels in 4 categories. The number in the . . .
– Upper left corner shows a 1.5 times increase (50%) in hydraulic systems and diesel engines (applies to gas engines too)
– Upper right corner shows result if tests were done for rolling element bearings
– Lower left corner corner shows result if tests were done for journal bearings and turbo machinery
– Lower right corner corner shows result if tests were done for gear boxes

Cheap oil filters work
@ 40µm
Good oil filters work
@ 25µm
FilterMag reaches below
3µm
Contamination Control Systems
It’s the Small Stuff That’s Killing Your Equipment
• Particles under 25µm go through oil filter • 3.5 times as many particles under 10µm (than over 10µm)
• Increase life by 6 times by filtering to 3 µm
• FilterMag can reach down to 1µm particles • Routinely see 2-3 ISO code drops • One time investment – a lifetime of protection
