This is a high-fidelity 3D model of a 200mm external rotor axial fan housing, industrial applications. It includes only the outer shell — no internal blades or motor components — making it ideal for:

• Spatial interference checking in refrigeration and HVAC systems
• Layout planning for mechanical enclosures
• Conceptual design and prototyping

Formats provided: STEP (.stp) and OBJ for visualization or basic mesh editing. Not optimized for real-time game engines due to high polygon count and lack of UV mapping/textures.
