Pressure filters are essential components in hydraulic systems, installed downstream of the pump and upstream of sensitive components such as precision valves, servos, and actuators. Their role is to retain contaminants in the hydraulic fluid, preventing premature wear, blockages, and malfunctions. Operating under high pressure (often above 200 bar)  they must ensure high mechanical strength, perfect sealing, and constant filtration efficiency even at high flow rates.

On fluid-hub you will find a full range of pressure filters designed to:

• Protect downstream components directly after the pump.

• Maintain high filtration efficiency even with fluctuating flow rates.

• Simplify maintenance with replaceable filter elements.

• Ensure compatibility with standard and special hydraulic fluids.

Available in multiple configurations, they meet the needs of both mobile machinery and complex industrial plants. The filtration rating depends on the required cleanliness class and operating conditions.

For complete system protection, pressure filters can be combined with other filtration solutions:

• Filtering elements: high-efficiency replacement cartridges.

• Suction filters: positioned before the pump to prevent coarse contamination.

• Return filters: located on the return line to the tank to capture impurities from actuators.

• Clogging indicators: devices that signal when filter elements need replacement.

Choosing a high-quality pressure filter means maximizing hydraulic system reliability, reducing downtime, and extending the service life of all components.
