Explore our high-efficiency filtration elements and customizable housing assemblies manufactured under IATF 16949 & ISO 9001 certifications.
Delivering high-integrity filtration solutions, custom housing engineering, and global supply resilience for automotive and heavy-duty machinery OEM/ODM clients.
Founded in 2019 and strategically headquartered in Changchun, Jilin Province, China—a historical powerhouse of China's automotive manufacturing cluster—Changchun Tolev Auto Co., Ltd. has rapidly emerged as an international leader in advanced fluid separation, air purification, and custom customizable filter housing systems. Spanning over 12+ years of collective industrial expertise among our engineering core, we combine cutting-edge materials science with lean manufacturing principles to serve tier-1 procurement partners across North America, Europe, Asia-Pacific, and the Middle East.
Modern internal combustion engines, commercial fleets, heavy construction equipment, and high-purity industrial fluid loops demand filter housings that can withstand severe mechanical vibration, thermal cycling (-40°C to +150°C), aggressive chemical exposure, and elevated operating burst pressures (up to 25 bar). As a specialized OEM/ODM Customizable Filter Housing Manufacturer & Exporter, Changchun Tolev Auto Co., Ltd. fills the critical gap between standardized catalog components and complex, bespoke powertrain geometries.
Our vertically integrated production architecture spans raw material formulation, structural finite element analysis (FEA), fluid dynamics simulation (CFD), ultrasonic welding, automated gasket curing, and multi-stage leak testing. By bridging technical innovation with optimized supply chain logistics, we empower global enterprises to lower Total Cost of Ownership (TCO) by up to 20% while extending element functional lifespan by 15% compared to standard market benchmarks.
Integrating fluid dynamics computational optimization, advanced polymer matrices, and multi-stage filtration technologies for harsh operational environments.
Utilizing 3D Computational Fluid Dynamics (CFD) modeling to analyze internal flow vectors, minimize turbulent backpressure, and equalize velocity distribution across media pleats. This engineering approach eliminates localized dust-loading hotspots and optimizes energy usage in compressed gas and intake air systems.
Housings engineered from die-cast aluminum alloys (ADC12/A380), corrosion-resistant 304/316L stainless steel, or glass-fiber reinforced polyamide polymers (PA66-GF30). Formulated to resist fatigue failure under rapid pulse-pressure cycles and aggressive synthetic lubricants.
Custom housings designed to accommodate hybrid filter elements combining synthetic melt-blown polyolefins, nanometer-scale electrospun fibers, micro-glass media, and coconut-shell activated carbon blocks for simultaneous particulate trapping and chemical gas deodorization.
Engineered for passenger cars, heavy-duty commercial fleets, off-highway machinery, and industrial compressed air systems.
High-efficiency air intake housings, spin-on oil filter bases, and multi-stage fuel filter assemblies. Engineered to meet strict Euro VI and EPA Tier 4 emission standards by protecting high-pressure common rail fuel injection (HPCR) systems down to 2 microns absolute.
Heavy-duty dual-stage air cleaner housings equipped with integrated centrifugal pre-cleaner ejectors. Built specifically for construction machinery, excavators, and mining haul trucks operating in ambient air particulate concentrations exceeding 1,000 mg/m³.
In-line compressed air filter housings and hydraulic fluid return housings. High-pressure rated vessels engineered with differential pressure indicators, dynamic condensate drains, and full compliance with ASME section VIII pressure vessel code guidelines.
Combining vertical integration, automated robotics, and agile prototype delivery to de-risk global enterprise procurement.
Accelerate your NPI (New Product Introduction) cycles. Utilizing rapid 3D printing of housing mockups, quick-turn aluminum tooling, and in-house CAD modification, our engineering team delivers testable prototypes in as little as 7 days.
High-volume standard order fulfilment achieved within 30 days. Backed by 9 fully automated production lines producing over 8 million filters annually, ensuring batch-to-batch consistency and zero production line downtime for global OEMs.
Every single filter housing undergo rigid inspection protocols including ISO 5011 fractional efficiency testing, bubble point integrity validation, burst pressure testing up to 35 bar, and automated 100% optical dimension checks.
From raw material verification to high-precision laser cutting, ultrasonic assembly, and quality packaging.
Full compliance with international standards, transparent technical documentation, and dedicated engineering consultation.
Our management systems adhere strictly to IATF 16949 automotive quality directives. Complete APQP (Advanced Product Quality Planning), PPAP (Production Part Approval Process) Level 3 documentation, and FMEA (Failure Mode and Effects Analysis) reports are provided for all OEM programs.
All filter housings and element materials comply fully with EU REACH regulations, RoHS toxic substance restrictions, and CE safety directives. Non-toxic, heavy-metal-free plating and recyclable thermoplastic housings support circular economic frameworks.
Our dedicated customer service and engineering teams operate round-the-clock (24/7) to provide immediate technical consulting, CAD draw review, post-delivery logistics tracking, and custom packaging personalization.
In-depth technical answers addressing custom housing specifications, testing metrics, MOQ, and international logistics.
Additional OEM/ODM replacement elements, activated carbon cabin filters, and inline compressor modules.
