Hydraulic Filter Elements for Construction Machinery

Return Line, Pressure and Suction Filter Elements

• Return line filter elements: filter hydraulic oil returning to the tank
• Pressure filter elements: used in the pressure circuit to protect downstream components
• Suction filter elements: installed upstream of the pump on the suction side
• Spin-on types: system-dependent filters used as replaceable units within specific hydraulic systems
• Coreless and mesh elements: for specific designs and filtration tasks

The installation position within the system is decisive. Return, pressure and suction elements differ in function, design and load capacity and are not interchangeable.

Identification by Reference Number, Design and System Integration

Hydraulic filter elements are identified by reference number, design and installation position and must match the existing filter housing and system configuration.

Visually similar elements often differ in dimensions, sealing concept, filtration rating or pressure resistance and are not automatically system-compatible.

Correct Assignment of Return, Pressure and Suction Elements

Return elements reduce particle contamination in the tank. Pressure elements protect valves and control units within the pressure circuit. Suction elements protect the pump on the intake side.

Correct selection requires full compatibility with the existing filter housing and its position within the hydraulic system.

Filtration Rating, Pressure Range and Element Design

Hydraulic filter elements vary depending on application in filtration rating, media, construction type and allowable differential pressure or operating pressure range.

Incorrect filtration or unsuitable element design leads to increased differential pressure, premature wear or system malfunction.

Filter Housing, Installation Position and System Environment

Hydraulic filter elements are always selected in relation to the existing filter housing and its installation position. Compatibility with the installed system is decisive.

They are directly linked to return line filters, pressure filters, suction filters and inline filters.

Additional system components include hydraulic filter accessories and off-line filtration systems.

Selection Criteria for Hydraulic Filter Elements

• Reference number: unique identification of the installed element
• Installation position: return line, pressure line, suction side or inline
• Design: element, spin-on, coreless or mesh type
• Filtration rating: matched to system requirements
• Pressure and system design: compatible with the existing filter housing

Check Before Ordering

• Reference number of the existing element
• Position of the installed filter housing in the system
• Element design and dimensions
• Filtration rating and pressure range
• Housing and sealing configuration

Hydraulic Filter Elements Within the System

Hydraulic filter elements are part of the category hydraulic filters for construction machinery and operate as replaceable components within existing return, pressure, suction and inline filtration systems. Correct assignment to the installed filter housing and system position is essential.
