1 Identity-Giving FunctionFunção Identitária
Function class
FiltrationFunction ⊑ DesignedFunction
Realized in
FiltrationProcess ⊑ PlannedProcess
The identity-giving function is filtration (separation of particles/contaminants from fluid streams). This function is already established for the general Filter class, and in-line filter inherits this same basic function.
2 Genus DeterminationDeterminação do Gênero
Filterbfo:Object (BFO_0000030)
Filter is the most specific appropriate superclass from the parent candidates. An in-line filter IS a filter with additional installation constraints. Filter is already enriched in our ontology with function: FiltrationFunction, genus: Separator.
3 Differentia SpecificaDiferença Específica
∃hasInstallationMethod.InLineInstallation ⊓ ∃supportedBy.ConnectedEquipment

An in-line filter is distinguished from other filters by being installed directly within a fluid line and supported by the connected piping or equipment rather than having independent structural support.

The key differentia is the installation method - being 'in-line' means integrated directly into the flow path and structurally supported by the connected equipment/piping. This is a constructive (physical configuration) differentia rather than a functional one.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

In-line filters inherit the basic filter element from the genus, but additionally require specific inlet/outlet connections that enable direct integration into piping systems without independent support structures.

physical separation of particles/contaminants from fluid stream
Standard filtration signature - one contaminated fluid input, two outputs (cleaned fluid and retained contaminants). Same as general Filter class since function is identical.
