What needs to be known when changing a hydraulic filter

Hydraulic filters need to be changed to ensure that the hydraulic system works efficiently. However, the timing on when these filters should be changed is unclear. Going by the manufacturers specifications is one option, but there are others who recommend creating a fixed maintenance schedule while some say that you should only change the filter once the equipment’s performance starts to drop.

Understanding why you need to change the filter and the timing involved is important. The one source of failure in a hydraulic system is fluid contamination, so therefore your systems need to be kept as clean as possible to avoid this situation. This dirt can block the filter and eventually affect the fluid pressure. Contaminated fluid will begin to pass through the system. Should this happen, the system will need to be flushed which will require downtime and extra costs. These contaminants when left too long in the system can also damage the other components requiring them to be replaced.

To prevent contamination a maintenance schedule could be kept avoiding changing the filters too late or too early as both can cause extra expenses and additional downtime. When new technology, components and information is received the thoughts around how and when to change the filters do adjust.

It is also important to know that systems are different, and what works for one may not work for another, or a closed loop system may need different maintenance requirements that an open loop system.
