Your Strategic Partner in High-Precision Diesel Filtration Systems and Heavy-Duty Engine Protection Solutions Across the Pacific Northwest.
Send Inquiry NowAs a premier Secondary Fuel Filter Manufacturer & Exporter in Seattle, we understand that the Pacific Northwest is a cornerstone of global trade and industrial innovation. Seattle's unique geography—home to the Port of Seattle and the bustling I-5 corridor—demands extraordinary reliability from diesel engines. The local economy relies heavily on maritime logistics, heavy-duty trucking, and large-scale infrastructure projects, all of which operate under stringent environmental regulations and the challenging, humid weather of the region.
In Seattle, the industrial landscape is shifting toward ultra-clean diesel technology. With the rise of Tier 4 and Tier 5 engine standards, the role of a Secondary Fuel Filter has become more critical than ever. Primary filters handle large particles and water, but our secondary filters are engineered to capture microscopic contaminants as small as 2 microns, protecting expensive high-pressure common rail (HPCR) systems from catastrophic failure.
Founded in 2019 and headquartered in Changchun, Jilin Province, China, Changchun Tolev Auto Co., Ltd. is a leading manufacturer specializing in automotive filtration solutions. With over 7 years of expertise, we have become a global player in the automotive filter industry. Our modern 5,000 sqm facility, equipped with 9 advanced production lines, serves over 30 countries worldwide.
We are committed to innovation, quality, and customer satisfaction, positioning ourselves as a trusted partner for filtration solutions across the globe, providing seamless export services to major hubs like Seattle, Washington.
Puget Sound’s maritime fleet, from ferries to fishing vessels, operates in high-moisture environments. Our secondary fuel filters prevent water-induced microbial growth and corrosion in fuel systems, ensuring non-stop operations for Seattle's marine economy.
With massive tech campus expansions in Redmond and Seattle, heavy machinery is under constant use. We provide specialized filters for John Deere and Perkins engines, ensuring that dust and debris from construction sites never compromise engine performance.
The Pacific Northwest is a leader in adopting biodiesel. Modern secondary filters must now be compatible with higher concentrations of bio-compounds. Our filters use advanced synthetic media designed to handle the unique solvency and viscosity of biodiesel blends.
Our filters reduce pollutants, engine wear, and maintenance costs, ensuring optimal performance. By implementing a high-efficiency secondary filter, fleet managers in Seattle can extend fuel injector life by up to 2x.
Our filters last 15% longer than industry standards (based on third-party testing) and meet global emission requirements, helping local businesses stay compliant with WA State eco-regulations.
