A gas cyclone separator is a separator that separates solid particles or liquid droplets from gas using centrifugal force generated by cyclonic flow geometry.
PT-BR
Um separador ciclônico de gás é um separador que separa partículas sólidas ou gotículas líquidas do gás usando força centrífuga gerada pela geometria de fluxo ciclônico.
Formal Axioms
Semi-formal (Aristotelian)

Axiomatization Decision Log
1 Identity-Giving Function
Function class
SeparationFunction ⊑ DesignedFunction
Realized in
SeparationProcess ⊑ MechanicalSeparation
The identity-giving function is separation - specifically separating solid or liquid particles from gas of different density. This reuses the existing SeparationFunction from the enriched separator class.
2 Genus Determination
Separator
The most specific appropriate superclass is 'separator' which is already enriched in our ontology. Gas cyclone separator is clearly a subtype of separator, inheriting the basic separation function but with the specific cyclonic mechanism differentia.
3 Necessary Parts

No necessary parts recorded (concept may be primitive at this level).

All gas cyclone separators must have these basic components to create and utilize cyclonic flow for separation
4 Process Participation Signature ⟨I, O, T⟩
Inputs (I)
FluidMixture — containing solid particles or liquid droplets
Outputs (O)
PortionOfGas — reduced solid/liquid content
FluidMixture — concentrated particles/droplets
Transformation (T)
physical separation through centrifugal force - no chemical change, only physical redistribution
Takes contaminated gas stream and separates it into clean gas and concentrated contaminants using centrifugal force
5 Axiom Mode Decision

Necessary conditions only — modelled as a primitive universal (⊑, SubClassOf). Identity is grounded in designed function and cannot be reduced to a property checklist.

Constructive type defined by cyclonic mechanism. Under Open World Assumption, any device with cyclonic flow chamber could be falsely classified as gas cyclone separator, including specialized multi-stage cyclones or hybrid separator designs that should not be forced into this standard maintenance category.
Disjointness Axioms
centrifuge
C1: centrifuge. Incompatible separation mechanisms - filters use physical barriers, centrifuges use mechanical rotation, while gas cyclone separators use flow-induced centrifugal force
Cross-Standard Observations
Only one source (CFIHOS) provides definition. The definition clearly emphasizes the static nature and centrifugal force mechanism, distinguishing it from other separator types.
