Air Filtration Solutions for the Automotive Manufacturing Industry
Industry Overview
Vietnam’s automotive manufacturing industry is growing strongly, with participation from major groups such as Toyota, Thaco (Kia/Peugeot), VinFast, and Hyundai Thanh Cong.
Automobile assembly plants require specialized air filtration systems, particularly in areas demanding high quality control such as paint booths and electrostatic painting zones.
Challenge
The paint booth area is one of the largest sources of air pollution in an automotive plant. The spray-painting process generates several agents that must be controlled:
- Overspray: Residual paint particles ranging from 1–100 µm adhere to product surfaces, causing paint quality defects.
- VOCs (Volatile Organic Compounds): Generated from paint solvents such as toluene, xylene, and methyl ethyl ketone.
- Isocyanates: Toxic chemical vapors from two-component PU paints, harmful to worker health.
- Strict exhaust treatment requirements under occupational safety and environmental standards before air is released outside.
Camfil’s Solution for Automotive Paint Booths
Camfil supplies a multi-stage air filtration system for automotive paint booths, simultaneously controlling paint dust, fine particles, and VOC gases.
The system consists of 3 filtration stages:
- Stage 1 — Camfil Paint Stop pre-filter: Captures large overspray paint particles, protecting downstream filter stages and extending system service life.
- Stage 2 — Camfil F7/F9 fine filters: Remove fine paint particles, achieving high filtration efficiency per the ISO 16890 standard.
- Stage 3 — Activated carbon molecular filter: Adsorbs VOCs, solvent vapors, and chemical compounds generated during painting.
The solution helps maintain a clean air environment inside the paint booth, ensuring paint surface quality and meeting industrial exhaust treatment requirements.
Economic Benefits
- Improved paint finish quality by reducing dust and contaminants in the booth air.
- Reduced defect rate from paint surface flaws.
- Extended service life of painting equipment and reduced maintenance costs.
- Protects worker health while meeting occupational safety and environmental requirements.
- Air Filtech is a supply partner for paint booth air filtration solutions at multiple automotive assembly plants in Vietnam.
