What happens when the maximum allowable pressure drop of a filter is reached?

When the maximum allowable pressure drop of a filter is reached, it signifies that the filter has become clogged or excessively dirty, creating a significant barrier to fluid flow. In this situation, the filter can no longer effectively trap particles and, as a result, may allow larger contaminants to pass through the medium. This occurs because the filtering material can become saturated, and the flow must continue, leading to a compromise in the filter's ability to perform its intended function.

Allowing particles to pass through can lead to various issues in the hydraulic system, including potential damage to components downstream and decreased overall efficiency. Understanding this process emphasizes the importance of regular maintenance and timely replacement of filters to ensure optimal system performance and protection.
