For automotive manufacturing spray booths, primer/topcoat/clearcoat lines, drying ovens, wax injection and VOC exhaust treatment across the entire process, Yiran® provides a three-stage complete filtration solution from booth supply air purification, oven high-temperature filtration to exhaust emission treatment, ensuring zero paint finish defects and environmental compliance.
Automotive painting is the critical process determining vehicle appearance quality. A single 10μm particle in booth air can form a visible defect on the painted surface, leading to rework or scrapping. Paint shop filtration systems must simultaneously address booth supply air purification, oven high-temperature and VOC emission challenges.
Approximately 30-50% of paint material becomes suspended overspray during spraying. If not captured promptly, overspray particles settle back onto vehicle bodies causing "dirt" defects. Booth supply air carrying environmental dust and HVAC-generated particles are also major sources of paint defects. Spray booths require ISO 7-8 supply air cleanliness; efficient multi-stage filtration and overspray capture are fundamental to zero-defect production.
E-coat (180-200°C), primer (150-180°C) and topcoat (140-160°C) ovens require purification of large volumes of recirculated hot air. Conventional filters deform, release fibers or thermally decompose above 120°C, contaminating vehicle paint surfaces. Oven filters must maintain structural stability at 120-250°C, zero fiber shedding, zero harmful gas release, and withstand repeated heating/cooling cycles.
Booth ambient temperature and humidity directly affect atomization quality, leveling and drying speed. Typically 23±2°C and 60±5%RH are required. High-resistance filters force AHU fans to accelerate, increasing energy consumption and causing temperature rise disturbances. Low-resistance filtration solutions that simultaneously meet cleanliness and temperature/humidity precision are a technical challenge.
Paint shops are the largest VOC emission source in vehicle plants, from benzenes, esters, ketones in solvent-based coatings. Air pollution prevention laws and local standards increasingly tighten VOC limits (some regions ≤30mg/m³). End-of-pipe activated carbon filters and catalytic oxidation equipment require effective particulate pre-filtration protection to extend core media life.
Yiran® automotive paint solution covers filtration needs across booth supply air, oven recirculation and VOC exhaust treatment.
