Explore our high-performance filtration modules engineered to improve efficiency and longevity in industrial and automotive applications.
Founded in 2019 and headquartered in the industrial hub of Changchun, Jilin Province, China, Changchun Tolev Auto Co., Ltd. is a leading manufacturer specializing in advanced automotive filtration solutions. With over 7 years of deep industry expertise, we have positioned ourselves as a key player in the global filtration ecosystem.
Our modern 5,000 sqm production facility, integrated with 9 automated manufacturing lines, serves over 30 countries. We continuously invest in pioneering R&D, ensuring our filtration systems meet strict European and North American efficiency mandates, helping global businesses lower energy usage and improve process longevity.
Sourcing energy-efficient air and oil filtration elements from Changchun, Jilin offers unique economic, structural, and technical benefits. Our processes reduce total costs while ensuring high build quality.
By producing critical components in-house—including custom steel casings, thermoplastic components, and premium synthetic filter media—we control our supply chain, optimize material usage, and lower wholesale prices by up to 20%.
Our raw materials and finished filters undergo rigorous laboratory testing. We evaluate dust-holding capacities, pressure resistance, and efficiency under simulated extreme environments in compliance with ISO 5011.
Our technical team can design and build prototype samples within 7 days. This allows global clients to validate new configurations and design iterations quickly without standard market delays.
Clean air and fluids are critical across many applications, from heavy machinery operating in dust clouds to high-performance passenger vehicles and industrial baghouses.
Minimizing fleet downtime requires robust air cleaners that protect engines from abrasive particulate matter. Our premium air filters maintain uniform airflow, helping engines run efficiently and reducing fuel consumption over long operating periods.
Tractors and excavators operate in high-dust and debris environments. Our secondary fuel filters, combined with heavy-duty air cleaners, protect engine systems from premature wear, ensuring reliable performance in demanding field operations.
Using Nomex Aramid baghouse filter socks helps manufacturing plants limit particulate emissions. These high-temperature, chemistry-resistant components enable industrial facilities to satisfy strict regional environment protection standards.
Our reverse osmosis housings and PPH filter housings provide chemical-resistant, high-pressure solutions for clean drinking water and chemical fluid management, ensuring process safety and reliability.
Global environmental mandates and efficiency targets are shaping the future of air and fluid filtration. To meet these demands, our engineering team focuses on three key technological areas:
By keeping pace with these design shifts, Changchun Tolev Auto Co., Ltd. ensures that your supply chain remains compliant with evolving global environmental regulations.
Precision manufacturing requires specialized machinery, structured quality control workflows, and quality raw materials. Here is a look at our daily operations and processes:
Managing global procurement processes requires checking that potential suppliers meet key commercial and technical standards.
Our energy-efficient air cleaners hold CE markings, showing compliance with European safety, health, and environmental standards. This simplifies import procedures within European economic zones.
We work to build long-term trust by maintaining complete traceability of our raw materials, sharing third-party performance metrics, and offering access to our engineering team for custom projects.
We maintain a standard order turnaround time of 30 days. We also offer expedited shipping and custom packaging designs to help clients meet their commercial delivery schedules.
