The Application axis of Wet Curtain market taxonomy segments demand into industrial, commercial, and infrastructure uses. Industrial applications—spanning metal fabrication, food processing, and chemical plants—represent the largest share, roughly 45 % of total market value, driven by stringent occupational‑health regulations and the need for high‑efficiency contaminant capture. Commercial settings such as retail complexes, hotels, and hospitals account for about 35 % of the market, where aesthetic considerations and moderate airflow control drive adoption of quieter, low‑maintenance air curtains. Infrastructure deployments—including airports, railway stations, and public transit hubs—contribute the remaining 20 %, reflecting growing public‑health initiatives and the requirement for large‑scale barrier solutions in high‑traffic zones. This application‑focused Wet Curtain segmentation aligns directly with the pie‑chart data, illustrating the relative economic weight of each end‑use and supporting strategic forecasting for manufacturers and investors.
