Description Attribute

ComponentClass

Enumeration of possible compressor types.

DisplacementType

Enumeration of possible displacement types.

LubricationType

Enumeration of possible lubrication types for the compression process of a compressor.

NumberOfStages

Number of stages the compressor has available.

VariableFlow

Indicates if a compressor has a variable or fixed flow.

VariableFlow

0:FalseState

'Fixed flow' means the product offers no control for changing the volume flow independent of pressure.

VariableFlow

0:TrueState

'Variable flow' means the compressor package allows an intentional change in volume flow rate, most obviously by VSD but also by adjustable guide vanes in turbo compressors or by valve controls in piston compressors or other means.
