Abstract
Context and Aim
Industrial workers, particularly painters, face significant health risks due to prolonged exposure to airborne dust and fine particulates. While personal protective equipment (PPE) such as respirators exists, adoption remains low due to discomfort, restricted mobility, and usability challenges. This project aims to develop a wearable air curtain system designed to reduce dust exposure while ensuring seamless integration into daily tasks without interfering with workflow or comfort.
Approach
The research employs a multi-method approach to ensure both technical efficiency and user acceptance. Computational Fluid Dynamics (CFD) simulations are used to optimize nozzle airflow distribution, ensuring maximum dust protection. Power efficiency analysis is conducted to minimize energy consumption while maintaining effective performance. Iterative prototyping and lab testing refine the system’s functionality, weight distribution, and ergonomics to enhance wearability. To evaluate usability, user studies with industrial painters are conducted, incorporating observations, interviews, and wearability trials to assess comfort and practicality in real-world settings. Additionally, the design is guided by and evaluated with PPE safety regulations, including CE standards, to ensure alignment with industry safety benchmarks.
Results
Findings from CFD simulations and real-world testing will inform nozzle geometry improvements, while user feedback will drive ergonomic refinements. By integrating technical validation with human-centered design, this project aims to create a practical, market-ready air curtain PPE solution that enhances worker safety, comfort, and adoption, ultimately improving protection against hazardous dust in industrial environments.
