Hydraulic fluid is the most important part of every hydraulic system. In hydraulics, no system works without a proper volume of hydraulic fluid. Also, any variation in fluid level, fluid properties, etc.. can damage the entire system we are using. If the hydraulic fluid has this much importance, then what will happen if it gets contaminated?

The risk of hydraulic fluid contamination increases based on the increased usage of the hydraulic system. Leakages, rust, aeration, cavitation, damaged seals, etc… make the hydraulic fluid contaminated. Such contaminated hydraulic fluids created problems are classified into degradation, transient, and catastrophic failures. Degradation is a failure classification that affects the normal working of the hydraulic system by slowing down the operations. Transient is an intermittent failure that occurs at irregular intervals. Finally, catastrophic failure is the complete end of your hydraulic system. The contaminated hydraulic fluid problems can become severe. Then, how do we protect the hydraulic system from contaminants?

Hydraulic fluid filtration is the only solution to eliminate contaminants from fluid in use.  Particle filtration using different types of filters will remove the contaminant particles like metals, fibers, silica, elastomers and rust from the hydraulic fluid. In this article, we can discuss more on hydraulic filters.
