Detailed introduction of product materials
As a washable and reusable pre filter element, PI8130DRG10 is made of a material completely different from disposable fiberglass filters. Our factory strictly benchmarks the DRG series metal filter process to enhance wear resistance, corrosion resistance, and blockage resistance. It is suitable for high-frequency flushing and long-term cyclic operation conditions. The material configuration of each component is as follows:
-Filter screen: Adopting multi-layer 304 stainless steel precision woven filter screen, with uniform warp and weft weaving and regular mesh holes, it combines 10 μ m precision filtration with ultra large flow capacity. The filter screen has been polished and passivated to resist corrosion and oil erosion, and is not easily deformed or damaged. After blockage, impurities can be cleaned by high-pressure air blowing, water rinsing, ultrasonic cleaning, and other methods. It can be reused repeatedly to effectively reduce the cost of long-term maintenance consumables and completely eliminate the problems of glass fiber filter powder loss and secondary pollution.
-Internal and External Support Skeleton: Thickened 304 stainless steel perforated skeleton, with strong overall rigidity, can effectively resist the impact of high flow fluid and negative pressure difference of the oil filter, avoiding filter collapse, bulging, and deformation. The skeleton has a high porosity and extremely low flow resistance, which will not cause flow loss to the front oil circuit and ensure stable purification efficiency of the oil filter.
-Sealing rubber ring: high quality NBR nitrile rubber sealing ring is standard configuration, which is oil resistant, high temperature resistant, anti-aging, and has excellent resilience and sealing performance. It closely fits with the filter chamber to eliminate oil leakage and air intake problems, and ensure the sealing stability of the prefiltering system. FKM fluororubber seals can be upgraded for high temperature and corrosive oil conditions.
-End cap structure: Precision stamped metal end caps are firmly integrated with the filter screen and skeleton using seamless pressing technology, without delamination or cracking hazards. The installation and positioning are precise, with tolerances fully matching the original filter, and suitable for repeated disassembly and cleaning operations.

Core advantages of the product
Compared to traditional disposable fiberglass filter cartridges and ordinary inferior metal filter cartridges, our factory's PI8130DRG10 washable filter cartridge has significant advantages in working conditions, perfectly adapting to the high-frequency operation requirements of pre filtration:
-Can be repeatedly cleaned and reused, greatly reducing costs: The stainless steel filter structure supports multiple cleaning and regeneration uses, without frequent replacement. Compared with disposable filters, the long-term operation and maintenance consumables cost is reduced by more than 60%, suitable for long-term continuous filtration operations of enterprises.
-Low resistance and high flux, high purification efficiency: The precision woven filter screen is transparent and uniform, with low oil resistance and high flow rate, suitable for high flow purification conditions of oil filters, without filter clogging or flow attenuation problems, ensuring oil purification efficiency.
-High strength and erosion resistance, long service life: The all metal structure is resistant to wear, corrosion, and fluid impact, and is not afraid of damage caused by large particle impurities. Its structural stability far exceeds that of conventional filter cartridges, and it is suitable for harsh impurity conditions.
-Pre protection, protecting backend precision equipment: intercepting large particle impurities and oil sludge clumps in advance, effectively reducing the filtration load on backend precision filters, oil pumps, and valve groups, extending the service life of precision accessories, and reducing the frequency of equipment failures and shutdowns.
Frequently Asked Questions (FAQ)
Q1: What is the cleaning cycle and method for metal filter cartridges?
A: Under normal operating conditions, the pressure difference can be raised to 0.2 MPa for cleaning. High pressure air blowing, specialized oil flushing, or ultrasonic cleaning methods can be used to clean impurities before being put back into use. After multiple cleaning failures, a new filter element can be replaced.
Q2: Can this filter element be used for precision filtration at the back end?
A: Not recommended. This filter is positioned as a pre-processing filter, focusing on high flow, reusability, and interception of large particle impurities. The precision purification at the back end still requires the use of high-precision fiberglass filters for better filtration effects.
Q3: Will the metal filter screen experience wire shedding or deformation?
A: I won't. Our factory adopts high-density weaving technology and reinforced skeleton. The filter mesh is tightly woven and has strong integrity. Under normal working conditions, there will be no shedding or deformation, and there is no risk of secondary pollution. The working stability is excellent.
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. In addition to the full range of MAHLE replacement oil filters, we also specialize in PALL, HYDAC, Leemin and other full range oil filters and filters, matched with LYC-A series movable oil filters and oil coalescence dehydration filters, providing one-stop solutions for industrial oil impurity removal and water filtration problems.
Q5: What other filtering categories are included in the factory's main business?
A: Our factory is a one-stop industrial filtration source manufacturer, with main business covering four core areas: industrial oil filtration, industrial water filtration, natural gas filtration, and industrial air filtration. We can customize various imported substitute filter elements, domestic standard filter elements, and complete sets of filtration equipment, suitable for multiple industry scenarios such as power, metallurgy, chemical, gas, and shipbuilding.
