Filter Element Upgrades

After water, particulate is the most common and damaging contaminant found in hydraulic and lubricating systems.

Removing insolubles and maintaining low particulate levels is important to protect the lubricant from rapid breakdown and the equipment from premature failure. Dust and other particulates are normally much harder than steel, which is why they are so harmful to mechanical surfaces and are the underlying cause of abrasive wear.

There is a wide range of particulate removal filters available in the market place. Unfortunately, these filters are frequently sold according to micron ratings that do not include an efficiency rating. The term “beta ratio” is generally used to compare filters, but with many companies selling their filters at different beta ratios, a more detailed understanding is required to directly compare.

A simple method is to look at the overall % efficiency of a filter at a given micron rating. This is essentially the batting average of a filter. With some filters removing as little as 50% of the particulate contamination that passes through them, there is significant room for improvement in regards to proper filter selection.

From an equipment perspective, you can easily double the life of your mechanical systems by reducing particulate levels, but more importantly eliminate a common failure mechanism thereby significantly improving reliability.
