Explore our top-tier selection of precision-engineered replacement filters, customizable cartridge housings, and industrial separation systems.
Addressing the complex demands of modern industrial processing, environmental compliance, and heavy machinery protection across the globe.
In the bioprocess and pharmaceutical sectors, contamination is not an option. Our CE-certified stainless steel single cartridge filter housings (SS304/SS316L) provide sanitary, crevice-free environments that prevent bacterial growth and ensure complete product purity during critical liquid separation phases.
Mining, construction, and agricultural equipment operate under extreme particulate loads. Our robust cabin air filters, compatible with major global brands like Volvo and Caterpillar, utilize advanced non-woven media and activated carbon to safeguard operators and sensitive engine systems from premature wear.
Precision manufacturing relies heavily on clean, dry compressed air. By integrating high-efficiency oil separators and precision coalescing elements (such as our Hankison-compatible replacements), we help factories eliminate oil aerosols, water droplets, and sub-micron particulates, reducing downtime by up to 25%.
What makes a filter housing truly "user-friendly"? At Changchun Tolev Auto Co., Ltd., we define user-friendliness through the lens of human-centric engineering and operational ergonomics. Our designs focus on minimizing the Mean Time to Repair (MTTR) and eliminating the risk of bypass leaks during routine maintenance.
Key features include tool-free quick-closure mechanisms, swing-bolt designs that allow rapid cartridge change-outs, and self-aligning internal guides that guarantee perfect element seating every single time. By optimizing the internal fluid dynamics, we have also reduced the clean pressure drop ($\Delta P$), resulting in significant energy savings for continuous-flow industrial operations.
Furthermore, our housings feature integrated vent and drain ports, allowing operators to safely depressurize and drain the vessel before servicing, minimizing chemical exposure and maintaining a clean, hazard-free workspace.
Navigating regional regulatory frameworks while providing tailored engineering support for diverse industrial applications.
All our filter housings destined for the European Union strictly comply with the Pressure Equipment Directive (PED) 2014/68/EU and carry the CE mark. We utilize certified raw materials and conduct non-destructive testing (NDT), including radiographic and hydrostatic pressure tests, to ensure complete compliance with EN 13445 standards.
For our clients in the United States and Canada, we offer housings designed in accordance with ASME Section VIII Division 1. Our automotive and heavy machinery filtration products meet or exceed SAE and ISO 5011 testing standards, ensuring seamless integration into OEM supply chains and compliance with EPA emission regulations.
With rapid industrialization in the APAC region, we provide localized technical support and fast-turnaround customization. Our manufacturing facility is certified under ISO 9001:2015 and IATF 16949:2016, guaranteeing that every filter housing shipped to regional distributors meets the highest global quality benchmarks.
A global leader in automotive and industrial filtration solutions, combining 12+ years of industry heritage with state-of-the-art automated manufacturing.
Founded in 2019 and headquartered in the industrial hub of Changchun, Jilin Province, China, Changchun Tolev Auto Co., Ltd. (operating in close synergy with Nangong Tongda Auto Parts Co., Ltd) has evolved into a premier manufacturer and exporter of advanced filtration systems. Spanning a modern 5,000 square meter facility, our operations are powered by 9 fully automated production lines designed for maximum precision and scalability.
With over 12 years of deep industry expertise, our engineering team is dedicated to solving complex particulate separation challenges. We control every stage of the manufacturing process—from the sourcing of premium synthetic media and high-grade stainless steel to final assembly and rigorous testing. This vertical integration allows us to deliver products that last 15% longer than standard industry alternatives while reducing overall procurement costs for our partners by up to 20%.
Our commitment to quality is validated by our extensive certification portfolio, which includes ISO 9001, IATF 16949, and ISO 5011. Every single filter housing undergoes over 12 strict quality checks, including pressure resistance validation, weld integrity inspections, and sealing efficiency tests, before leaving our factory floor.

How we are driving the next generation of smart, sustainable, and ultra-efficient filtration technologies.
We are actively developing filter housings integrated with differential pressure sensors and IoT transmitters. These smart systems will monitor real-time particulate loading and automatically alert maintenance teams before a critical pressure drop occurs, preventing system bypass and optimizing element service life.
Our R&D team is pioneering the use of electrospun nanofibers in our air and liquid filter elements. By creating a highly porous network with sub-micron fiber diameters, we can achieve exceptional fractional efficiency for ultra-fine particles while maintaining an incredibly low resistance to flow.
In alignment with global carbon reduction goals, we are transitioning to fully recyclable thermoplastic end-caps and biodegradable synthetic media options. Our goal is to provide high-performance filtration solutions that minimize environmental impact throughout their entire lifecycle, from production to disposal.
