#### 6.2.3.19 IfcFlowTreatmentDeviceType

| Type d'appareil de traitement de fluide
| Filter - Typ

The element type IfcFlowTreatmentDeviceType defines a list of commonly shared property set definitions of a flow treatment device and an optional set of product representations. It is used to define a flow treatment device specification (the specific product information that is common to all occurrences of that product type).

A flow treatment device is a device used to change the physical properties of the medium, such as an air, oil or water filter (used to remove particulates from the fluid), or a duct silencer (used to attenuate noise). Flow treatment types (or the instantiable subtypes) may be exchanged without being already assigned to occurrences.

The occurrences of the IfcFlowTreatmentDeviceType are represented by instances of IfcFlowTreatmentDevice or its subtypes.
