Filter Differential Pressure vs Service Life Curve

Documents the ΔP vs service life relationship that governs filter replacement intervals. The curve starts low (clean element initial resistance), rises with dirt accumulation, and accelerates as the element approaches its rated capacity. Three critical thresholds define failure modes: the service indicator threshold (visual/electronic alert to replace), the bypass valve opening pressure (element protection at cost of unfiltered flow), and the element collapse pressure (structural failure under pressure differential).

Line chart with contamination load on X-axis (from NEW to END OF LIFE) and differential pressure on Y-axis (low to high). A smooth S-shaped curve rises from bottom-left. Three horizontal dashed threshold lines: yellow dashed at mid-height labelled SERVICE INDICATOR, orange dashed above it labelled BYPASS OPENS, red dashed near top labelled COLLAPSE RISK. Three shaded background zones: faint green below service indicator (normal operating range), faint yellow between service indicator and bypass (service interval exceeded), faint red above bypass (bypass active, unfiltered flow). Circle marker at intersection of curve and service indicator threshold.
