Detailed introduction of product materials
Our factory's PI4105PS25 filter element optimizes the material ratio for high flow circulation filtration conditions, abandoning the shoddy craftsmanship of low-priced filter elements, inferior filter materials, and thin material skeletons in the market. The overall durability, flowability, and stability are comprehensively compared to the original factory. The material configuration of each component is as follows:
-Filter material: Adopting multi-layer composite gradient fiberglass filter material, compatible with Mahler PS series high-end filtration technology, with uniform and transparent pore distribution. The outer loose structure quickly intercepts large particle impurities and oil sludge clumps, while the inner dense structure finely purifies the oil, balancing 25 μ m high-efficiency filtration and ultra large oil flow rate. The filter material is cured with high-temperature resin, and the fibers are firmly bonded. It cannot be washed away by oil flow for a long time without shedding powder or falling off, and will not cause secondary pollution to the oil circuit. Its pollutant holding capacity far exceeds that of ordinary paper filter elements, and it is suitable for 24-hour continuous operation of the equipment.
-Internal and External Support Skeleton: Adopting thickened galvanized metal punching skeleton, the overall support strength is high, which can effectively resist the impact of large flow oil flow and slight negative pressure difference, and prevent the problems of filter cartridge flattening, deformation, and collapse. The skeleton perforation rate has been optimized to minimize oil resistance, ensure stable system circulation flow, and adapt to high flow oil supply conditions.
-Sealing rubber ring: high quality NBR nitrile rubber seal is standard configuration, which has excellent oil resistance, high temperature resistance, aging resistance and resilience performance. It closely fits with the end face of the filter chamber, completely eliminates oil leakage, air inlet and pressure relief problems, and ensures stable sealing of the filter system. Fluororubber seals can be customized for special high-temperature and corrosive medium conditions.
-End cap structure: Precision one-piece stamped metal end cap, tightly bonded to the filter material using high-temperature hot pressing composite process, with high bonding strength and not easy to peel off or crack. Accurate installation positioning, with tolerances that conform to the original factory standards, and 100% compatibility with the original filter installation structure.

Core advantages of the product
Compared to ordinary alternative filter cartridges on the market, our PI4105PS25 filter element has been optimized for high flow cycle performance, solving pain points such as easy blockage, insufficient flow, and easy deformation of conventional filter cartridges. Its core advantages are outstanding:
-High throughput and low resistance, suitable for continuous operation: designed with a large folding area gradient filter material, it has low oil resistance and high flow rate, which will not add additional burden to the circulating oil circuit. It perfectly adapts to the all-weather uninterrupted operation of industrial equipment, ensuring stable oil supply.
-High pollutant holding capacity, extended maintenance cycle: Multi layer layered pollutant holding structure can accommodate large areas of sludge and metal impurities, effectively delaying the rate of pressure difference rise. Compared with ordinary filter cartridges, the service life is greatly improved, reducing the frequency of equipment shutdown and replacement, and improving production efficiency.
-Wide adaptability to working conditions and strong universality: The 25 μ m filtration accuracy is suitable for the vast majority of industrial conventional hydraulic and lubrication systems, which can intercept harmful impurities to protect equipment, and will not cause frequent blockages due to high accuracy, making it suitable for various general equipment working conditions.

It can operate for a long time without deformation or damage, and has excellent working stability.
-Non destructive in-situ replacement, cost reduction and efficiency improvement: 1:1 replica of original factory size and sealing structure, no equipment modification required, easy disassembly and assembly, ready to use, replacing high priced imported parts with extremely low procurement costs, significantly reducing enterprise operation and maintenance costs.
Frequently Asked Questions (FAQ)
Q1: Is the 25 μm filtration accuracy suitable for use in precision hydraulic systems?
A: Not suitable for high-precision precision servo systems. This filter element is a universal high flow coarse and fine filtration element, focusing on high flux and high pollutant absorption, suitable for conventional hydraulic and lubrication systems; It is recommended to use high-precision filter cartridges of 5 μm and 10 μm for precision high-pressure servo oil circuits.
Q2: What is the reason for the rapid increase in pressure difference when using the filter element?
A: Mainly caused by excessive oil contamination and accumulation of impurities in the system, it is a working condition problem rather than a quality issue with the filter element. It is recommended to regularly check the cleanliness of the oil and replace the filter element in a timely manner when the pressure difference reaches 0.2MPa to avoid affecting the operation of the equipment.
Q3: Can filter material be customized according to special working conditions?
A: Support customization. According to special working conditions such as high temperature, high humidity, and corrosive oil, fluororubber seals, thickened filter materials, and reinforced skeletons can be replaced to adapt to various harsh working environments.
Q4: Apart from MAHLE filter elements, what other oil filtration products do you have?
A: Our factory has a complete line of oil filtration products, which can meet the purification needs of industrial oil products under all working conditions.
