Detailed introduction of product materials
Our PI21004DNSMX3 replacement filter element is benchmarked against the original material standards of MAHLE in Germany. We optimize the material ratio for low-pressure and high flow circulation filtration conditions, while also considering high precision, low resistance, and long-term durability. We eliminate problems such as powder loss, easy blockage, and deformation of inferior replacement filters on the market. The core material configuration is as follows:
-Filter material: Adopting imported grade resin cured gradient glass fiber filter material, replicating PS series high-precision filtration process, and multi-layer composite structure to achieve layered filtration. The outer coarse filter intercepts large particles of oil sludge and impurities, while the inner layer accurately captures 4 μ m fine metal debris. The filter material is treated with high temperature and high pressure solidification, with firmly bonded fibers and uniform and transparent pores. The oil resistance is extremely low, and it can operate continuously for a long time without falling off or damage. Its pollutant carrying capacity far exceeds that of ordinary paper filters, effectively avoiding secondary pollution of the oil circuit and adapting to 24-hour uninterrupted operation conditions.
-Supporting skeleton: Adopting high-strength galvanized metal support structure, lightweight and high-strength design, suitable for low-pressure and high flux working conditions, effectively resisting the impact of oil flow, preventing filter deformation and collapse, anti-oxidation and corrosion resistance, suitable for humid and dusty industrial environments, greatly extending the service life of the filter.
-Sealing accessories: original NBR nitrile rubber seals of the same type are standard, which are oil resistant, high temperature resistant, anti-aging, and tightly sealed without gaps. They perfectly fit the cavity of the duplex filter, eliminate oil leakage and air inlet problems, and ensure the stability of the sealing of the low-pressure circulating system.
-End cap structure: Precision stamping integrated metal end cap, using high-temperature composite bonding technology, firmly bonding the filter material and end cap without easy detachment, precise installation positioning, 100% compatible with original filter installation structure.

Frequently asked questions
Q1.Will the 4 μm high-precision filter lead to high oil resistance and insufficient flow?
A: No. This filter element adopts a gradient low resistance fiberglass structure, designed specifically for low-pressure and high flux circulation conditions. While ensuring high-precision filtration of 4 μm, it effectively reduces oil flow resistance without affecting the normal circulation flow of the system, and is suitable for continuous operation needs.
Q2: Is this filter suitable for high-pressure hydraulic systems?
A: Not suitable for high-pressure working conditions, this filter element is a low-pressure dedicated filter accessory, suitable for a maximum of 6.3MPa low-pressure system, mainly used for lubrication circulation and low-pressure hydraulic equipment. It is recommended to use a dedicated high-pressure filter element for high-pressure working conditions.
Q3: How long is the normal replacement cycle for filter elements?
A: The service life can reach 3-6 months under clean lubrication conditions, and 1-3 months under harsh conditions with high oil impurities. It is recommended to replace the equipment based on a core pressure difference of 0.22MPa to ensure stable system operation.
Q4: Apart from MAHLE filter cartridges, 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.
