Clogging indicators are essential devices for monitoring the condition of hydraulic filters. Their role is to detect the degree of contamination of the filter element and signal when the pressure drop reaches the preset limit, indicating the need for maintenance or replacement. Effective clogging monitoring is crucial to maintain system efficiency, reduce the risk of breakdowns, and extend component service life.

At fluid-hub you will find clogging indicators designed for precision and reliability, even under the harshest operating conditions. Our models are available in mechanical versions (flag type, push-button) or electrical versions (with signalling contacts for remote control systems), with various settings to suit different filter types and system configurations.

The indicators are compatible with all major filter types available on our website:

• Filtering elements: the core of the filtration system, trapping contaminant particles to protect the circuit.

• Suction filters: installed upstream of the pump to prevent coarse impurities from entering the circuit.

• Pressure filters: located downstream of the pump, ensuring high filtration efficiency even at high pressures.

• Return filters: installed on the return line to filter oil before it flows back into the tank.

Using a clogging indicator allows you to carry out maintenance only when necessary, avoiding premature or delayed replacements that could compromise proper system operation.

For comprehensive system monitoring, clogging indicators can be paired with dedicated pressure switches that continuously control the operating pressure of the circuit. For electrical connection of versions with signalling contacts, see our range of cables and connectors.
