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
