With the refined development of the manufacturing industry, spray booths, as core equipment in the coating process, have drawn wide attention in terms of technological iteration and environmental protection performance. This paper conducts an in-depth analysis on the technical essentials and industrial applications of spray booths.
I. Three Main Types of Spray Booths
Dry Spray Booth
It adopts activated carbon or filter cotton to adsorb paint mist, suitable for small and medium-batch operations with low maintenance costs.
Water Curtain Spray Booth
It captures paint mist particles via a water circulation system, with an environmental compliance rate exceeding 90%, widely used in the automobile maintenance industry.
VOC Treatment Spray Booth
Equipped with integrated catalytic combustion devices, it can decompose harmful gases such as benzene series, complying with the new national standard GB 16297-2025.
II. Core Technical Indicators
Air volume control: Wind speed shall be stably maintained at 0.3-0.5m/s in accordance with ISO 12944 standards.
Filtration efficiency: High-end models achieve a filtration rate of 99.8% for 10-micron particles.
Energy consumption comparison: Water curtain type saves 30% more energy than dry type, yet raises wastewater treatment costs by 15%.
III. Industrial Application Data
According to the 2025 White Paper on China Coating Equipment Industry:
The automobile manufacturing industry accounts for 47% of the total demand for spray booths.
The annual procurement volume of eco-friendly equipment increases by 23%, with Shandong and Guangdong as the core markets.
