The Parker GLF Series Low Pressure Tank Top Return Line Hydraulic Oil Filter delivers efficient contamination control for hydraulic circuits required to operate in highly demanding environments. The filter is ideally suited for applications where high system reliability and minimal downtime are critical, including heavy equipment and machinery used in mining, construction, marine, forestry, material handling and agricultural operations.

The GLF Series features an innovative design that provides maximum filtration capacity and extended element life, while maintaining low pressure drop, even in cold start conditions. High-efficiency Quantµmfiber™ glass media is available in ratings 2, 5, 10, and 20 micron. Optional magnetic prefiltration is available for added protection in environments where ferrous contaminants are present while the bypass is opened. Magnetic prefiltration also extends life by preventing ferrous materials from settling on the filter media.

The GLF Series Return Line Filter’s unique inside-to-outside flow path minimizes contaminant exposure to the reservoir during element change-out. Other notable features include pressure gauge and switch ports for visual or electrical switch monitoring, which makes it easy for operators to determine when the element needs to be serviced. Additionally, the filter features a versatile two-port design for enhanced installation flexibility.

Standard available port connection range:

• Single G12 up to G24
• Dual G24
• Single R24 up to R48
• Dual R24 up to R48
