Qingdao Hainai Composite Filter Element, as another outstanding achievement in the domestic substitution of industrial oil purification, leverages independently developed composite filtration technology to break the industry’s limitations of single-function traditional filter elements. With its innovative three-in-one integrated structure, it redefines the efficiency and quality of industrial oil purification, providing cost-effective and feasible domestic substitution solutions for domestic industrial lubricant oil enterprises, replacing conventional single-function filter elements and imported filter elements.
Unlike traditional filters that are limited to single dehydration or impurity removal, this composite filter innovatively integrates three core purification functions—dehydration, solid impurity removal, and oxidation product elimination—into one unit. Featuring a multi-layered composite filtration material design, it effectively adsorbs free and emulsified moisture in the oil, intercepts various solid impurities (such as metal debris and dust), and simultaneously breaks down and removes harmful substances like gum and asphaltene generated from oil oxidation. The synergistic effect of these three functions eliminates the need for multiple single-function filters, significantly simplifying equipment filter configurations, reducing installation space requirements, while enhancing the continuity and efficiency of oil purification. This also lowers the labor and material costs associated with filter replacement and maintenance.
The moisture content of the purified oil is strictly controlled at ≤0.03%, minimizing risks such as equipment corrosion, oil passage blockage, and component wear caused by moisture. The oil cleanliness consistently meets the NAS≤8 standard, quickly restoring a clean and transparent state after passing through the filter element. This ensures stable operation of industrial equipment like hydraulic and lubrication systems from the source, extends equipment lifespan, and reduces production losses due to equipment failure and downtime.
The product features a modular design, compatible with various equipment models such as Qingdao Hainar L60, L30, L150, S60, S30, and S150. It requires no modifications to the original equipment, allowing for direct replacement and immediate operation. With convenient installation and strong adaptability, it reduces the costs of equipment upgrades and filter replacements for enterprises. This filter is suitable for both online and offline purification devices. Made from high-strength, high-adsorption composite materials, it boasts core advantages such as large dirt-holding capacity, strong water absorption, and extended service life. Compared to traditional single-function filters, its lifespan is increased by over 30%, reducing the frequency of filter replacements and further lowering procurement and maintenance costs for enterprises.
This filter element can be widely used in various industrial applications such as forging, stamping, automotive parts processing, and rubber tire vulcanization. Whether in harsh operating environments with high temperature and high pressure or in oil purification scenarios with multiple impurities and high moisture content, it delivers stable purification performance. It is suitable for deep purification of various industrial oils, including hydraulic oil, lubricating oil, and gear oil. Qingdao Hainai Composite Filter Elements break the technological monopoly and price barriers of imported filter elements through proprietary core technologies, reliable product quality, and cost-effective solutions. They not only achieve comprehensive replacement of traditional single-function filter elements but also provide more competitive oil purification options for domestic industrial enterprises, helping them reduce costs, improve efficiency, enhance quality, and upgrade processes, demonstrating the robust capabilities of domestic industrial filter elements.
