Engineered to deliver exceptional filtration efficiency, extended operational lifespan, and compliance with the most stringent global standards including ISO 5011 and IATF 16949.
Founded in 2019 and headquartered in the industrial hub of Changchun, Jilin Province, China, Changchun Tolev Auto Co., Ltd. has established itself as an authoritative leader in global filtration solutions. Leveraging over 7 years of specialized development and production expertise, we design, engineer, and manufacture advanced air quality improvement filters, engine ventilation modules, and specialized heavy industrial baghouse collectors.
Our operation spans a modern 5,000 square meter facility utilizing 9 high-capacity automated production lines. We do not just supply products; we engineer critical environmental assets that protect heavy industrial machinery, refine passenger cabin micro-environments, and optimize gas turbine intake efficiencies across 30+ countries.
Understanding the micro-dynamics of particulate separation is essential for compliance with evolving global environmental regulations and equipment security protocols.
We provide ultra-high efficiency filtration media that capture 99.97% of airborne contaminants down to 0.3 microns. Essential for electronic fabrication plants, hospitals, and pharmaceutical environments seeking cleanroom standard validations.
Handling harsh emissions from aluminum and steel smelting demands thermally robust filter media. Our custom aramid bag filters prevent toxic particle release, ensuring compliance with local ambient air quality standards and EPA limits.
We work directly with Tier-1 system assemblers to supply cabin air filtration and high-performance engine intake arrays that reduce internal combustion engine wear, enhance fuel economy, and lower carbon emissions.

At Changchun Tolev Auto Co., Ltd., our engineering principles focus on minimizing pressure drop while maximizing dust holding capacity (DHC). Through rigorous control of fiber diameter distribution, we ensure that our filters do not cause excessive system backpressure. Reduced backpressure directly correlates with enhanced energy conservation in industrial exhaust fans and better fuel efficiency in automotive engines.
Our core capabilities extend to structural component design. For example, our Epman fuel pump brackets are CNC machined from high-tensile 6061-T6 anodized aluminum, protecting vital fuel elements from high-frequency vibration and structural fatigue in racing and heavy duty commercial environments.
From advanced raw material testing to automated assembly and multi-level pressure resistance tests, our ISO 9001 and IATF 16949 certified facility manages every critical step.
Every filter batch passes ISO 5011 verification prior to logistics release.
How our filtration solutions meet diverse operational challenges across multiple regions and sectors.
With rigorous local guidelines (such as the EU Clean Air Package and US EPA regulations), importing companies face intense scrutiny regarding material toxicity and waste management. Tolev utilizes REACH and RoHS compliant raw materials. Our premium car cabin air filters, embedded with active carbon elements (e.g., CF10285 replacement series), are engineered to neutralize ozone, particulate matter, and nitrogen oxides (NOx) to protect passengers inside dense urban zones.
In desert locations, mining sites, or smelting facilities (like those using our high-temperature Aramid Baghouse Filters), standard filters clog rapidly, leading to frequent downtime. Our heavy-duty air filter elements are treated with specialized hydrophobic and surface-loading coatings. They extend operational lifespan by 15% under extreme dust storms and heavy machinery operations, protecting heavy diesel generators and compressor systems.
At Changchun Tolev Auto Co., Ltd., we continuously invest in clean technology, anticipating industry challenges years before they emerge.
Critical engineering and supply chain questions answered by our technical staff to support your strategic procurement decisions.
All our filtration designs undergo exhaustive quality testing under ISO 9001 and IATF 16949 international standards. Our automotive intake products are validated using the ISO 5011 standard test dust procedures to guarantee filtration efficiency and dust holding capabilities. Furthermore, our products intended for Western European markets carry CE certification, demonstrating absolute conformity with EU consumer safety and environmental rules.
We control our supply chain through deep vertical integration, selecting only high-grade synthetic fibers and robust frame structures. Rather than utilizing basic surface-loading paper, we use gradient-density multi-layered media. This depth-loading technology captures larger particles in the outer layers and smaller ones in the inner matrix, preventing premature clogging and extending physical service intervals by 15%.
Yes. For industrial dust collector systems, such as aluminum smelting furnaces, we supply needled aramid felts (Nomex equivalent) capable of withstanding continuous operating temperatures of 200°C to 240°C. We also offer specialized chemical treatments, including acid-resistant, flame-retardant, and water-repellent coatings, customized to the precise chemical makeup of your flue gas emissions.
Our dedicated engineering R&D department can supply detailed 3D CAD modeling and initial functional prototypes in just 7 days from specification receipt. Once approved, our standard manufacturing lead time for bulk export orders is 30 days, supported by expedited processes for urgent industrial requirements.
In addition to filter media, we manufacture specialized structural installation brackets, such as the Epman fuel pump brackets. These are CNC milled from high-tensile 6061-T6 aluminum alloys and finished with an anti-corrosive anodized layer. They provide secure, vibration-dampened installation for dual pumps and inline filters in demanding automotive environments.
Our packaging processes are designed for long-distance ocean transit. We utilize moisture-proof barriers, heavy-duty corrugated storage cartons, and secure palletization. Each batch is clearly labeled with product codes and batch details to streamline custom clearance protocols at global ports of entry.
