New Filtration Technology for Industrial Applications
1. Background
A well-known auto parts manufacturer upgraded its paint booth ventilation system to meet stricter VOC emission standards. The client required a more efficient, longer-lasting, and large-airflow-compatible activated carbon filter.Traditional honeycomb carbon panels suffered from high pressure drop and short service life, failing to meet the company’s high-throughput production schedule.
2. Client Requirements
Pollutants: Benzene, ester, ketone VOCs
Air volume: ≥ 5,000 m³/h per unit
Operating condition: Continuous operation with peak spraying emissions
Service life: ≥ 6 months
Installation: Plug-in replacement, no ducting change
3. SINFT Solution
We developed a custom activated carbon cartridge filled with high-iodine-value pellet carbon and a robust steel frame.| Specification | Detail |
| Carbon type | Pellet, iodine ≥950 mg/g |
| Housing | Galvanized or stainless steel |
| Dimensions | φ320 × H660 mm (customizable) |
| Airflow resistance | ≤ 200 Pa at rated flow |
| Carbon load | 12–15 kg per cartridge |
| Maintenance | Tool-free quick-change design |
4. Results
Excellent VOC removal: >95% removal efficiency (benzene series)
Stable pressure drop: <20% rise after 3 months
Compatible structure: No modifications to paint booth required
Extended service life: >8 months before replacement
The client ordered a full batch of filter cartridges and plans to expand use across more production lines.
Effective paint booth VOC treatment isn’t just about carbon quantity—it’s about finding the optimal balance of adsorption performance, airflow, service life, and cost.
SINFT delivers tailored activated carbon filtration systems for high-load VOC control, especially in industries like automotive painting, chemical VOC abatement, electronics, and coating lines.
