Advantages of product material structure
P-351A-04-10U focuses on small size, high precision, and high stability, solving the pain points of small space, easy blockage, and deformation of compact filter elements:
1. Compact gradient fiberglass filter material: using high-density folded fiberglass technology, maximizing the filtration area in a small space, intercepting large particle impurities on the outer layer, and finely purifying 10 μm fine particles and sludge on the inner layer, balancing accuracy and pollutant holding capacity, avoiding the shortcomings of small filter elements with small pollutant holding capacity and easy blockage.
2. Integrated reinforced support structure: Exclusive small skeleton design, balanced opening ratio, improves structural strength without increasing volume, avoids deformation and collapse when the pressure difference of small-sized filter elements increases, and adapts to flow fluctuation conditions.
3. Precise sealing adaptation design: The micro sealing structure precisely fits the original filter housing, with no deviation in sealing, eliminating bypass and leakage problems that are prone to occur in narrow spaces, and ensuring the effectiveness of filtration.
4. High temperature curing and anti fiber shedding process: The filter material is immersed and cured at high temperature, and the fibers are tightly bonded without shedding due to long-term oil flow erosion, preventing small fibers from entering the oil circuit and causing secondary pollution, ensuring the stable operation of precision equipment.

Applicable industries and working conditions scenarios
This model is designed specifically for small and medium-sized hydraulic and lubrication equipment with limited space, with precise adaptability to specific scenarios
-Precision small machine tools: CNC equipment and small machining centers are equipped with hydraulic filtering circuits to stabilize the accuracy of equipment operation.
-Light industry automation equipment: automation supporting hydraulic station, small power unit circulation filtration.
-Power auxiliary equipment: small oil stations in power plants, auxiliary hydraulic devices for oil purification.
-Injection molding auxiliary equipment: small injection molding auxiliary hydraulic system, oil temperature machine hydraulic circuit filtration.
-Imported compact equipment maintenance: replacement of domestically produced spare parts for complete sets of equipment equipped with 351A series filters.
Core advantages of the product
1. Compact and precise, suitable for small installation spaces: The compact and exclusive design perfectly adapts to the filtering points inside the device that are limited in space, without installation and adaptation issues.
2. Small size, large dirt absorption, long service life: Optimized folding process, maximizes filtration area in small spaces, alleviates the problem of small filter cartridges easily clogging, and reduces replacement frequency.
3. Stable accuracy, eliminating secondary pollution: The cured fiberglass filter material has no shedding or delamination, ensuring stable filtration accuracy and effectively protecting small precision valve groups and oil components.
4. Low resistance and energy-saving, without affecting equipment operating conditions: The flow resistance is small, which will not increase the back pressure of the oil circuit, and will not affect the response and work efficiency of small equipment.
5. High cost performance localization replacement: Non destructive replacement of imported filter cartridges, fast supply, low price, perfect solution to the maintenance problem of small imported spare parts.

Frequently Asked Questions (FAQ)
Q1: Can the compact P-351A-04-10U replace conventional large-sized filter cartridges?
A: No, due to different sizes and structures, it cannot be used interchangeably. It is only compatible with the 351A series compact filters and cannot be replaced with conventional filters at will.
Q2: Small filter cartridges have a small amount of dirt, will they frequently clog?
A: Our factory has optimized the gradient filter material structure, which has better pollutant holding capacity than ordinary small filter elements; Suitable for conventional clean working conditions, it is recommended to add pre coarse filtration for harsh impurity working conditions.
Q3: Can it be used for filtering small servo assisted circuits?
A: As an auxiliary circuit filter, it is recommended to use a 3 μm high-precision dedicated filter element for the core servo precision circuit to ensure equipment accuracy.
Q4: Apart from TAISEI KOGYO filter elements, what other oil filtration products do you have?
A: Our factory has a complete product line for oil filtration. In addition to TAISEI KOGYO replacement filters, we also produce PALL, HYDAC, and Leemin series hydraulic filters, which are matched with mobile oil filter machine and coalescence dehydration filters to achieve integrated filtration of oil impurities and water.
Q5: What other filtering categories does the factory produce?
A: The source manufacturer covers industrial oil filtration, industrial water filtration, natural gas filtration, air filtration, and can produce imported replacement filters, domestic standard filters, and complete sets of filtration equipment. It supplies to multiple industries such as power, metallurgy, chemical, and gas.
