Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
CompressionFunction ⊑ DesignedFunction
Realized in
CompressionProcess ⊑ PlannedProcess
The identity-giving function is compression - all definitions specify 'compress and supply' or 'blowing' which involves pressurizing gas. This is the same CompressionFunction that defines compressors in general, as blowers are a specific type of compressor for medium pressure applications.
2 Genus DeterminationDeterminação do Gênero
compressorbfo:Object (BFO_0000030)
Blower is a specific type of compressor distinguished by operating at medium pressure and medium volume flow. The enriched 'compressor' class already exists with CompressionFunction. Among parent candidates, 'compressor' is the most specific appropriate superclass that captures the compression identity.
3 Differentia SpecificaDiferença Específica
∃hasOperatingParameter.MediumPressureRange ⊓ ∃hasOperatingParameter.MediumVolumeFlowRange

operates at medium pressure and medium volume flow ranges, distinguishing it from other compressors

The differentia is the medium pressure and medium volume flow operating range explicitly stated in CFIHOS and POSC definitions. This distinguishes blowers from fans (low pressure, high volume) and turbo/reciprocating compressors (high pressure, lower volume).
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These are the universal components needed for any blower to realize its compression function, regardless of specific design (axial, centrifugal, etc.)

TransformationTransformação
mechanical energy added to gas to increase pressure and maintain medium volume flow
Blowers take low-pressure gas and deliver it at medium pressure with medium volume flow, distinguishing them from fans (low pressure rise) and high-pressure compressors
Disjoint WithDisjunto com
Fan
C?: Fan [kind_ambiguous]. Fans operate at low pressure rise with high volume flow (incompatible signature), while vacuum pumps create negative pressure rather than positive compression
