How do Contaminants Enter Equipment Systems?

1. The milling process leaves metal particles under 10 microns down to and below 1 micron, in the pores of the machined metal parts. Parts washers typically are unable to adequately clean the parts from contamination under 40 microns.

2. Metal contamination is also present in the factory air, that is responsible for assembling all the equipment components into a final product. This airborne metal contamination then settles on the final product.

3. Once the equipment is assembled, new lube oil or fluids are then installed. All new fluids and lube oils have ferrous metal contamination 10 microns down to and below 1 micron in size, from the pipeline transportation, and refining processes as the result of corrosion and erosion.

4. After assembly and initial equipment start up, the break-in period creates additional metal wear contamination from below 1 micron to 10 microns.

5. Dirty fuel will inhibit combustion and cause blow by of the fuel and contaminants into the engine oil.

6. The air breather, although it is supposed to filter keep debris out of the engine, sucks in fine metal and silica contaminants from the air.

Common Contaminants in Fuel

  • Dirt/contaminants
  • Fuel by-products
  • Water
  • Particulates
  • Microbial Growth

These contaminants are usually introduced into fuel during the transportation, mixing or storage process.

Water can enter the fuel system when warm and moist air condenses on the fuel tank walls and condensation builds up, which causes corrosion of the tank or reservoir. Water in your tank can cause a number of problems, including reducing the lubricating qualities of the fuel, fuel injector seizure and engine damage. In addition, fungus and bacteria live in water, so when they are in introduced to a fuel system, they can cause premature injector wear and can plug traditional fuel filters.

Dirt, sediment and other contaminants also can cause premature fuel injector wear and traditional fuel filter clogging.
