HIGH PRESSURE FILTERS DFFX Series Reverse Flow Differential Pressure Optimized Filters 6090 psi up to 160 gpm Hydraulic Symbol or DFFX FILTER REVERSE FLOW CIRCUIT P Indicator Reverse Flow Valve BY-PASS VALVES (OPTIONAL) F18 Features DFFX Reverse Flow models filter fluid in the forward direction and bypass the filter element when the flow direction is reversed. O-ring seals are used to provide positive, reliable sealing. Choice of O-ring materials provide compatibility with petroleum oils, synthetic fluids, water-glycols, oil/water emulsions, and high water based fluids. Screw-in bowl/lid mounted below the filter head requires minimal clearance to remove the element for replacement; contaminated fluid cannot be washed downstream when element is serviced. Clogging indicators have no external dynamic seal. This results in high reliability due to magnetic actuation which eliminates a leak point. A poppet-type bypass valve (optional) located in the filter head provides positive sealing during normal operation and fast opening during cold starts and flow surges.
