AutoCAD DWG of Mechanical Ventilation Schematic with Detailed Layout

This DWG/CAD file contains a detailed 2D schematic diagram of a mechanical ventilation system. It includes duct runs, supply and return vents, airflow direction arrows, and connections between mechanical equipment. The design is useful for HVAC engineers, mechanical draftsmen, and building service designers who need precise layouts for ventilation in residential, commercial, or industrial buildings. The drawing can be used in construction documentation, system integration planning, or coordination with architectural and MEP plans. Because it shows the internal ventilation path clearly, it aids in analyzing pressure drops, balancing airflow, and ensuring proper ventilation coverage across zones.
