Detailed explanation of material and process
K3091852 belongs to high-precision high-pressure filter element, with 3 μm precision filter layer, using multi-layer gradient fiberglass composite filter material to gradually capture small particle pollutants. Under high-pressure conditions, the impact strength of the oil is high. The filter element is equipped with thickened punched metal support nets inside and outside to prevent the filter layer from collapsing and being damaged under high pressure differences. The filter material adopts resin curing process, with high strength of the filter layer and no risk of fiber detachment, meeting the high cleanliness requirements of the servo system for oil.
The end cover is made of thickened steel plate, welded and formed, with pressure resistant welds. The sealing groove size is strictly aligned with the original parts to ensure accurate positioning of the sealing gasket and prevent internal leakage under high pressure. Standard NBR nitrile seal, replaceable fluororubber seal for high temperature or special fire-resistant conditions. The entire filter cartridge has undergone pressure leakage testing and bubble integrity testing before leaving the factory to ensure stable precision filtration performance.

Factory substitution production advantages
Our factory has mature production experience in the field of high-pressure precision servo filter cartridges. The K series high-pressure filter cartridges have undergone multiple installation verifications. High pressure filter cartridges have extremely high requirements for welding, bonding, and support structures. The production workshop has a dedicated pressure testing station, and each batch is sampled for pressure impact testing to avoid filter cartridge failure under high pressure conditions. Supporting domestic metallurgical and power plant projects, as well as undertaking foreign trade orders, we can provide complete factory documentation. Technical engineers can assist customers in selecting oil cleanliness solutions.
FAQ
Q1: Will the 3 μ m precision filter be easily clogged?
A: Gradient structured filter materials balance accuracy and pollutant holding capacity; However, precision filter cartridges have requirements for the original contamination level of the oil, and it is recommended to add coarse filtration before the system to extend its service life.
Q2: Can this filter be used for phosphate ester fire-resistant fuel?
A: Sure, we need to replace the dedicated fluororubber seal. Please inform us of the medium type before placing the order.
Q3: Will long-term low temperature environment affect sealing performance?
A: Standard NBR minimum -25 ℃; Below this temperature, low-temperature special sealing materials can be selected, and customization can be communicated in advance.
Q4: Apart from ARGO 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. In addition to the full range of ARGO 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.
