The invention patent independently developed by Yuhang Technology - a hangar lift air supply system (patent number: ZL202211332443.1), meets the core requirements of hangar painting operations and achieves precise and energy-saving upgrades of the air supply system. The system can flexibly adjust the height of the air supply duct according to the painting operation scenario. When performing the painting operation on the body, the air supply duct in the body area can be accurately lowered to the specified height; When switching to the wing painting operation, the air supply ducts in the wing area are synchronously lowered to the corresponding designated height to ensure accurate coverage of the operation area, ensuring paint uniformity and process stability.

Compared with the problems of large jet attenuation and high energy consumption in traditional hangar air supply systems, this patented technology significantly reduces unnecessary air loss by accurately controlling high air supply. While fully meeting the requirements of various standards for aircraft painting processes, it can achieve energy savings of more than 40%. This not only improves the quality of painting operations, but also effectively reduces the energy consumption and carbon emissions of enterprise operations, demonstrating the technological innovation strength and green development concept of Yuhang Technology in the field of hangar ventilation.
