Question: 1 / 400

What happens when contaminants move past the filter medium?

Filtering efficiency increases

System performance improves

Contamination occurs

When contaminants move past the filter medium, contamination occurs. The primary function of a filter is to capture and retain particles and contaminants that could potentially harm hydraulic systems, reducing their efficiency and lifespan. If these contaminants bypass the filter, they can circulate through the system, leading to damage in critical components like pumps and valves, increased wear, and ultimately system failure.

In essence, the filter's efficiency is compromised, allowing for particulates to enter the fluid flow, which can lead to contamination of not just the fluid but also the equipment. This highlights the importance of regular maintenance and inspection of filters to ensure they are functioning correctly to avoid such issues in hydraulic systems.
