HVAC Ventilation Duct Pipe System 3D Model

This detailed 3D asset pack presents a fully assembled hvac ventilation system embedded inside concrete wall cavity. It includes rectangular galvanized air ducts round spiral metal pipes elbow joints tees reducers flexible connectors ventilation fans ceiling air diffusers return air grilles metal support brackets perforated protective mesh and fixing hardware. All components are modeled with accurate industry standard dimensions and realistic industrial metal textures. The models feature crisp metal seam flange bolt and welding line details to simulate real mechanical engineering construction. Every part is separated as independent objects so users can disassemble adjust and reorganize the duct layout freely according to their own mep design drawing. This asset is perfect for architectural visualization mep engineering presentation underground space parking lot basement commercial building industrial factory pipeline showcase construction animation and technical teaching demonstration. It supports pbr workflow with albedo roughness normal metallic and ao maps for realistic metal and concrete material rendering. The files are compatible with blender 3ds max maya cinema 4d unreal engine unity and most mainstream 3d design software. The topology is clean and optimized for rendering and real time engine use.
