What is the maximum micronic rating of non-cleanable filter elements used in hydraulic filtration?

The maximum micronic rating of non-cleanable filter elements used in hydraulic filtration is typically 5 microns. This rating is significant because hydraulic systems require a level of cleanliness to ensure optimal performance and reliability. Filter elements that are rated at 5 microns are capable of trapping contaminants that could cause wear or damage to hydraulic components, thus maintaining the integrity of the system.

Filtering at this level allows for the removal of particulates that are small enough to negatively impact hydraulic fluid behavior, while still allowing sufficient fluid flow. The choice of a 5-micron rating strikes a balance between filtration efficiency and maintaining system pressure and flow.

Higher micronic ratings, such as 10 or 15 microns, may not sufficiently remove all harmful contaminants that can lead to hydraulic system failures. Therefore, the selection of a 5-micron rating as the maximum for non-cleanable filter elements reflects both industry standards and engineering practices aimed at promoting system longevity and reliability.
