The Parker EPF Series is a high pressure, inline hydraulic oil filter that provides high-efficiency filtration for equipment in demanding environments, including mining, construction, marine, drilling, and agricultural applications. A unique feature of the EPF Series is that the filter element remains inside the filter bowl when performing a change-out. This can save over 500 mm of space envelope in comparison with traditional high pressure filters on the market. The filter element core is also reusable, which reduces waste by up to 50% when compared to conventional filters with non-reusable elements.

EPF Series filters serve as a highly economical filtration solution in high pressure range applications (up to 450 bar), where compact envelopes and excellent fatigue pressure ratings are critical. Specific examples include (but are not limited to) mobile working hydraulics, wind turbines, drive systems, pilot line filtration systems, servo controls, industrial working hydraulics, control systems, and reverse flow valve applications.

The patented design of the filter element allows for integration of the bypass valve and element core as re-usable parts in the filter bowl. This makes the filter secure and eliminates the risk of forgetting to re-install reusable parts during maintenance. Bypass settings are available up to 7 bar (100 psi) or no bypass versions when using patented, high strength filter elements. The principle is based on differential pressure measurement across the filter element.

The EPF Series is designed for use with EPF Series Replacement Elements and is available with various port connection types, filtration media (2, 5, 10, and 20 micron), indicators, and flow capacities (up to 700 L/min) to meet the unique requirements of customers’ hydraulic circuits.
