industrial blower 3d model

Industrial 120mm HVAC vent booster housing; meaning is must fit into common household vents. Rectangular mounting flange with screw holes. Central circular recessed fan bay for 120mm axial fan (105mm hole spacing). Aerodynamics: > 1. Inlet: Wide-radius bell-mouth trumpet intake to eliminate Vena Contracta and maximize laminar flow. 2. Outlet: Parallel teardrop airfoil louvers angled at 30 degrees to promote the Coanda effect for ceiling-attached room mixing. 3. Entrainment: Shrouded venturi gap to induce secondary air pull from the duct. Mechanical: Manifold geometry, 45-degree chamfers for support-free 3D printing. Integrated recessed cable raceway on the housing exterior. High-precision engineering aesthetic, matte finish, clean topology for CAD conversion.
