Filters play an important role in operating hydraulic equipment. Designed to remove small particles from fluids, they ensure hydraulic systems are free of contamination. However, these parts don’t last forever. Eventually, they become clogged with debris and need to be replaced. To help you keep your equipment in good shape, here is a quick look at the importance of replacing hydraulic filters and how often to do it.

What Are the Risks of a Clog?

Equipment Contamination & Failure

When a filter is clogged and can no longer collect debris, it will release contaminants back into the system with the fluids that flow through. These contaminants can infiltrate mechanical components and eventually cause them to operate inefficiently or fail. Equipment failure will require costly repairs and operational downtime that significantly impair your output capabilities.

Pressure Loss

Fluids may have trouble moving through a clogged device, resulting in a drop in pressure. Depending on your equipment, the restricted fluids may automatically flow through a bypass valve instead of the filter. While this built-in solution sustains proper pressure levels, it allows contaminants to flow freely to the rest of the equipment.  

If your system isn’t outfitted with a bypass valve, the built-up pressure may cause the filter to collapse and allow contaminants to flow through. The increase in pressure may also harm various components of the system, resulting in equipment failure.

When Is It Time to Change a Hydraulic Filter?

Recommended Maintenance Schedule

In general, follow your hydraulic equipment instructions to determine how often changes are needed. Typically, this schedule is based on a specific amount of service hours. However, clogs can develop before the recommended change schedule, so it’s a good idea to monitor performance, as noted below.

Visible Contamination

Monitor the fluids in the return line to ensure they remain clear. If you see any debris or contamination, the filtration system likely needs to be replaced.

Pressure Indicator Warning

Equipping your system with a pressure indicator will provide an early warning system. If the pressure drops below a certain level, this device will alert you, so you’ll have enough time to replace the filter before problems arise.
