Element Collapse
Filtration Performance
Also: filter collapse · media collapse · structural filter failure
Canonical Definition
The structural failure of a filter element under excessive differential pressure, in which the filter media and/or support structure collapses inward (for outside-in flow) or outward (for inside-out flow), irreversibly destroying the element's filtration integrity. Collapse releases accumulated contaminant directly into the downstream circuit. Collapse pressure is the minimum differential pressure at which a filter element will structurally fail, measured per ISO 3723 (collapse/burst test). ELIMFILTERS elements are designed with collapse pressures exceeding 21 bar to provide a margin above maximum bypass valve settings.
Engineering Context
Element collapse is a catastrophic failure mode that typically results from failure to replace an overloaded filter element, a stuck or absent bypass valve, or extremely high cold-start viscosity combined with rapid acceleration. Post-collapse contamination events require complete system flushing and inspection of downstream components.
