Multi-layer fine filtration, durable, customizable

　　Xinxiang Xingda Filter Co., Ltd., 30 Years of Industry Experience SANY Heavy Industry Official Certified Supplier

　　In construction, mining, infrastructure, and heavy machinery operations, engines rely on high-quality air filtration to maintain performance and prevent premature failure. Dust, sand, and fine particles are the biggest threats to engine life, often leading to increased wear, fuel consumption, unplanned downtime, and higher maintenance costs. For equipment owners and fleet managers, especially users of SANY Heavy Industry machinery, choosing reliable air filters is a direct investment in equipment stability and long-term value.

　　We are a professional filter manufacturer with 30 years of industry experience and are proud to be an official certified supplier of SANY Heavy Industry. For over three decades, we have produced more than 120 million filter elements, serving over 50,000 customers worldwide. Our stable partnership with SANY Heavy Industry has lasted for 15 years, supplying over 800,000 air filters annually with a defect rate controlled below 0.03%—far lower than SANY Heavy Industry's internal compliance standard of 0.1%. If you're looking for heavy-duty air filters that offer stable performance, long service life, and can withstand harsh operating environments (especially suitable for SANY Heavy Industry equipment), then you've come to the right place. Our air filters utilize advanced multi-layer fine filtration technology designed to protect the core components of engines. All performance indicators meet or exceed SANY Heavy Industry's stringent supplier requirements.

　　Using our air filters, you can reduce maintenance frequency by 40%, lower replacement costs by 35%, and ensure up to 99.8% equipment operational continuity. With 30 years of manufacturing experience and a long-standing partnership with SANY Heavy Industry, these filters offer a cost-effective solution that can extend the average engine life by 25%.

　　Key Performance Advantages

　　Multi-layer Fine Filtration for Efficient Engine Protection

　　Our air filter features a reinforced structure combining a metal mesh outer layer and high-precision filter media, forming a triple fine filtration system:

　　Primary filtration layer blocks coarse dust and impurities.

　　A 0.5μm polyester fiber layer efficiently captures fine particles.

　　An outer stainless steel mesh provides physical protection against damage.

　　Filtration efficiency is ≥99.5%, reaching up to 99.9%, effectively intercepting harmful pollutants and protecting engine components at the source.

　　Durable, Anti-aging, and Stable Operation

　　The filter is equipped with sealed end caps and high-density pleated filter media, offering excellent shock resistance. The filter media operates reliably over a wide temperature range of -40℃ to 120℃ and exhibits excellent anti-aging properties. The galvanized steel frame is rust-proof and deformation-resistant.

　　After 8000 hours of high-load testing, the pressure drop increase is only 1/3 of that of standard filters, extending service life by 30%.

　　Full-Scene Adaptability and Flexible Customization

　　Our air filters operate reliably in construction sites, mines, quarries, factories, and other harsh environments. We support customized sizes, filter media types, and structural designs to match different equipment models and operating conditions.
