Axiom type
LLM classification basis: structure-based → ⊑
Identity relative to genus Filter is given by a specific mechanism (layered coalescing media that merges liquid droplets so they drain, rather than straining out solid particulates), not a distinguishing function -- it performs the same FiltrationFunction as any filter.

FiltrationFunction → FiltrationProcess ⊑ MechanicalSeparation

COPI-Core operation
MechanicalSeparation via process parent MechanicalSeparation
LLM rationale:
Reused verbatim from the already-enriched genus 'filter' per the constructive-type rule: a coalescent filter removes contaminants from a fluid stream like any filter, differing only in the mechanism (coalescence of liquid droplets vs. straining of solid particulates).

Genus (genus proximum)
Most specific superclass — may be a domain class like "Valve" or an IOF-Core root.
BFO/IOF-Core Root
bfo:Object branch
bfo:ObjectAggregate branch
bfo:ImmaterialEntity branch
LLM rationale:
Parent candidate GAS FILTER is not itself enriched. Filter (already enriched, genus=Separator, function=FiltrationFunction, exported) is the closest enriched supertype, matching the physical form and general purpose (removing contaminants from a fluid) even though the removed-contaminant phase (liquid droplets, not solid particulates) and mechanism differ.

Conditions that distinguish
Coalescent Filter
from sibling classes under genus
Filter.
Only what is not already entailed by the genus.
Differentia expression
Differentia (natural language)
LLM rationale:
Two independent tertiary patents (triangulated) confirm the layered coalescing media pack as the defining structural element, distinguishing this from both a generic particulate Filter and the vessel-scale Coalescer.

Necessary Parts

no necessary parts · 1 candidate

Consider part-whole relations beyond subsumption:
hasComponentPartAtAllTimes (universal, structurally essential)
· hasComponentPartAtSomeTime (contingent, optional component)
LLM rationale:
Placeholder empty for Phase 3 -- CoalescingFilterMedia added via the Phase 1b follow-up write once source_definitions_used carries the verbatim tertiary patent quotes.
Candidate parts (unconfirmed)
Triangulated findings not yet confirmed as genus-wide. Not exported until promoted.
CoalescingFilterMedia
“They generally comprise several layers of filter media.”

Inputs (I)
Outputs (O)
Transformation (T)
LLM rationale:
Matches the canonical mechanical_filtration term (size/mechanism-based particle/droplet removal), same category as the genus Filter; two output streams (cleaned gas, drained liquid) reflect the coalescence-specific drainage step.
