RFB Series Direct return self-sealing magnetic return filter: guardian of hydraulic system cleaning

As the "blood circulation system" of modern industrial equipment, the stability of hydraulic system is directly related to the life and efficiency of mechanical equipment. The RFB series direct return self-sealing magnetic oil return filter developed by Henan Xinxiang Lifelte Filter Co., Ltd. provides a reliable guarantee for the oil purification of hydraulic system with its innovative design and high filtration efficiency, and becomes an indispensable core component in the field of industrial equipment maintenance. Product overview: Precise filtration, guard hydraulic system "heart" RFB series filter is designed for hydraulic system return pipeline, through the dual mechanism of high-precision filtration and magnetic adsorption, effectively intercept metal particles in the oil, rubber debris, seal wear products and other pollutants. Its "direct return self-sealing" structure design makes the filtration process more efficient, sealing more reliable, to ensure that the oil return path clean and safe. The product is widely used in construction machinery, mining equipment, metallurgical machinery and other high pollution, high wear working environment, to provide long-term protection for hydraulic system. 

Technical features: Multi-dimensional innovation, casting excellent performance Dual-effect filtration system RFB series adopts the dual mechanism of "gradient filtration + magnetic adsorption" : The primary filter layer intercepts large particle impurities, the secondary high-precision filter element (accuracy up to 10-20μm) captures micron level pollutants, and the built-in strong magnetic component absorbs ferromagnetic metal particles to achieve the dual purification of "physical interception + magnetic capture", and the filtration efficiency is as high as 99.5%. Self-sealing construction Innovative self-sealing design is the core highlight of the RFB series. When the system is shut down or the filter element is replaced, the self-sealing valve is automatically closed to prevent the leakage of oil and the reverse flow of pollutants to avoid secondary pollution. This design not only improves maintenance safety, but also extends the service life of the filter element and reduces maintenance costs. Corrosion resistance and high pressure filter body made of 304 stainless steel, strong corrosion resistance, adapt to harsh industrial environment; The optimized design of the internal flow path reduces pressure loss, and the maximum pressure can reach 35MPa, ensuring stable operation of the system under high pressure conditions. Intelligent monitoring and maintenance convenience Some models are equipped with a pressure difference indicator to monitor the blockage status of the filter element in real time. When the pressure difference exceeds the set threshold, the indicator light automatically warns the user to replace the filter element in time. The quick-release design allows maintenance to take only 5 minutes, significantly reducing downtime. Application scenario: Multi-industry coverage, to solve the pain point needs of construction machinery: excavator, crane hydraulic system exposed to dust environment for a long time, RFB filter effectively filter metal debris and rubber impurities, prevent the hydraulic valve stuck, prolong the life of equipment.

 Mining equipment application: In high wear scenarios such as shearer and mining hydraulic support, the high filtration accuracy of the RFB series ensures oil cleaning and reduces the failure and shutdown rate caused by pollution. Industrial manufacturing scenario: Precision machine tools, injection molding machines and other equipment have high requirements for hydraulic oil cleanliness, and RFB filters are filtered through the micron level to ensure high precision operation of the hydraulic system and reduce maintenance frequency. Market value: Balance of efficiency and cost art Traditional return oil filters often face problems such as easy blockage of the filter element, high maintenance costs, and poor sealing reliability. The RFB series achieves life extension through the integration of self-sealing structure, intelligent monitoring and efficient filtration technology: filter replacement cycle is extended by 30%-50%, reducing downtime loss; Cost optimization: Self-sealing design reduces maintenance labor costs and oil losses; Environmental benefits: Reduce equipment scrap caused by oil pollution, in line with the trend of green manufacturing. Conclusion: Technological innovation drives industrial reliability
