This 74 μm coarse filter element belongs to the system pre protection type filter element, mainly intercepting large particles of rust, welding slag, suspended sediment, large oil sludge, worn metal particles and other impurities in hydraulic oil and lubricating oil, effectively protecting core components such as precision filter element, hydraulic pump, proportional valve, plunger pump, etc., greatly reducing system failure rate, and stabilizing the operating efficiency of high flow hydraulic equipment.

Core competitive advantages of the product

1. Ultra high flow rate, low pressure loss without holding pressure: designed with a 74 μm large aperture filter, the oil resistance is extremely low, and there is no pressure attenuation or insufficient oil supply under high flow supply conditions, fully adapting to the high flow circulation needs of large hydraulic equipment.

2. Ultra high pollutant holding capacity, anti clogging and durable: With a thick and large capacity filter material structure, the pollutant holding space is sufficient, and the anti clogging ability for high pollution and harsh working conditions far exceeds that of ordinary filter elements, effectively extending the replacement cycle and reducing downtime maintenance times.

3. High strength structure, resistant to erosion and impact: thickened metal frame+double-layer protective net overall reinforcement structure, can withstand long-term erosion and system pressure fluctuations of high flow oil flow, and is not easy to deform, damage or fail after long-term continuous use.

4. Excellent pre protection effect, significant cost reduction and efficiency improvement: efficiently intercepting coarse pollutants, avoiding large particle impurities from directly impacting the precision hydraulic components at the back end, significantly reducing the loss rate of precision filter elements and equipment wear probability, and overall reducing system maintenance costs.

5. 100% original factory adaptation, easy disassembly and assembly: The external dimensions, installation interfaces, and assembly spacing are completely aligned with the original Parker 931881Q filter element, without the need for equipment modification or debugging adaptation. It can be directly replaced on the machine with zero adaptation error.

6. Clean process without secondary pollution: The entire hot melt integrated molding process has no adhesive bonding impurities, no fiber shedding, and the filtration process is clean and stable, without causing secondary pollution to the circulating oil, ensuring stable oil quality of the system.
