HISTORY New entity in IFC2x4
Type Use Definition IfcFilter defines the occurrence of any filter; common information about filter types is handled by IfcFilterType. The IfcFilterType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcFilterType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcFilterType has ports or aggregated elements, such objects are reflected at the IfcFilter occurrence using the IfcRelDefinesByObject relationship.
Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcFilterType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcFilterType.HasPropertySets. If both are given, then the properties directly defined at IfcFilter override the properties defined at IfcFilterType. Refer to the documentation at the supertype IfcFlowTreatmentDevice and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: (All Types)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.
Qto_FilterBaseQuantities
Material Use Definition The material of the IfcFilter is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcFilterType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:
Frame: The material used to construct the filter housing. Media: The material that is used for filtering particulates.
Port Use Definition The distribution ports relating to the IfcFilter are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the filter occurrence is defined by IfcFilterType, then the port occurrences must reflect those defined at the IfcFilterType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcFilter PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:
AIRPARTICLEFILTER
In (AIRCONDITIONING, SINK): Incoming fluid. Out (AIRCONDITIONING, SOURCE): Outgoing fluid.
COMPRESSEDAIRFILTER
In (COMPRESSEDAIR, SINK): Incoming fluid. Out (COMPRESSEDAIR, SOURCE): Outgoing fluid.
ODORFILTER
In (EXHAUST, SINK): Incoming fluid. Out (EXHAUST, SOURCE): Outgoing fluid.
OILFILTER
In (OIL, SINK): Incoming fluid. Out (OIL, SOURCE): Outgoing fluid.
STRAINER
In (DRAINAGE, SINK): Incoming fluid. Out (DRAINAGE, SOURCE): Outgoing fluid.
WATERFILTER
In (DOMESTICCOLDWATER, SINK): Incoming fluid. Out (DOMESTICCOLDWATER, SOURCE): Outgoing fluid.
