Full-Flow Filtration

Canonical Definition

A filtration arrangement in which the entire pump output passes through the filter element before reaching downstream components, ensuring all fluid is filtered on every pass. Full-flow filters are positioned in pressure, return, or case drain lines depending on system design. Pressure-line full-flow filters must withstand full system pressure and shock loads; return-line filters operate at near-reservoir pressure but handle the full flow rate including cylinder-regeneration flows. Full-flow filtration provides the primary contamination barrier for protecting all downstream components.

Engineering Context

Full-flow filtration rating must balance particle capture efficiency against flow capacity and differential pressure impact. An element that is too fine for the full flow rate will reach its service pressure differential rapidly, causing frequent bypass valve opening and degraded filtration. Full-flow and bypass filtration are complementary: full-flow handles the bulk of contamination at moderate efficiency; bypass polishing achieves the target cleanliness code.
