7.5.3.38 IfcFanType

7.5.3.38.1 Semantic definition

The flow moving device type IfcFanType defines commonly shared information for occurrences of fans. The set of shared information may include:

  • common properties with shared property sets
  • common representations
  • common materials
  • common composition of elements
  • common ports

It is used to define a fan type specification indicating the specific product information that is common to all occurrences of that product type. The IfcFanType may be declared within IfcProject or IfcProjectLibrary using IfcRelDeclares and may be exchanged with or without occurrences of the type. Occurrences of IfcFanType are represented by instances of IfcFan. Refer to the documentation at IfcFan for supported property sets, materials, composition, and ports.
