Ventilation Detail Drawing with Vertical Duct Layout and Pipe Sizes

This ventilation detail drawing is a professionally drafted AutoCAD file illustrating a vertical ventilation system with clear pipe routing and dimensional accuracy. The drawing shows the main ventilation duct alignment through multiple floor levels, branch connections, pipe diameter indications, and termination above roof level. All components are labeled with height references, floor level markings, and connection points, helping users understand airflow paths and installation sequencing. The detail clearly represents ventilation continuity across floors with proper offsets and fixing positions. The ventilation detail AutoCAD drawing is suitable for architects, civil engineers, and builders involved in building services coordination and construction documentation.
