Clogging Indicators

Hydraulic Filter Clogging Indicators

Monitor hydraulic filter restriction and identify when filter element replacement may be required with Flowfit’s range of hydraulic filter clogging indicators, manufactured by Filtrec.

As a hydraulic filter collects dirt, wear particles and other contaminants, the resistance to oil flow can increase. A clogging indicator provides a practical way to monitor this change and alert operators when the filter element is becoming restricted.

Available in visual and electrical configurations depending on the model, Filtrec clogging indicators can support routine maintenance, improve filter management and help maintain reliable hydraulic system performance.

Monitor Hydraulic Filter Condition

A hydraulic filter clogging indicator helps provide an indication of the condition of a filter element by monitoring pressure or restriction associated with the filter.

As contamination builds within the filter media, pressure conditions around the filter can change. Once the indicator reaches its specified setting, it can provide a warning that the hydraulic filter element may require inspection or replacement.

This allows maintenance teams to respond to actual filter condition rather than relying only on fixed replacement intervals.

Visual & Electrical Clogging Indicators

Depending on the Filtrec product selected, clogging indicators may provide different types of warning.

Visual Clogging Indicators
Visual indicators provide a local indication directly at the hydraulic filter, allowing operators or maintenance personnel to inspect filter condition during routine checks.

Electrical Clogging Indicators
Electrical indicators provide a signal that can be connected to a machine control system, warning light or alarm. This can be particularly useful on automated equipment or hydraulic systems where the filter is not easily visible.

Common Applications for Hydraulic Clogging Indicators

Clogging indicators are commonly used with:

• Hydraulic pressure filters
• Return line filters

Why Use a Filter Clogging Indicator?

Replacing hydraulic filter elements too early can increase maintenance costs, while leaving a heavily restricted filter in service for too long can affect hydraulic system performance.

A filter restriction indicator provides a more practical method of determining when the element requires attention.

By monitoring filter condition, operators can make more informed maintenance decisions and help ensure hydraulic oil continues to flow through the filtration system effectively.

Choosing the Right Hydraulic Clogging Indicator

When selecting a clogging indicator, consider the hydraulic filter series, operating pressure, indicator setting, connection type and whether visual or electrical indication is required.

The indicator must be compatible with the filter and operating conditions of the hydraulic system.

For systems requiring continuous electronic pressure measurement, Flowfit also supplies hydraulic pressure transmitters, alongside replacement hydraulic filter elements and complete filtration assemblies.
