New Oil Cleanliness
The new lubricant is one of many sources of solid particle contaminants. The lubricant raw materials are not pre-cleaned before being combined into a finished lubricant. The vessels used to blend the raw materials fill with blend-plant atmosphere each time the vessel is emptied. Additionally, each time the transport container (transport, haul truck, drum, oil can) drains down it is filled with the air from the immediate environment. Often the immediate environment is rich with microscopically sized particles. This study reveals the nature of the contaminant threat imposed by new lubricants.
