Core basic parameters of the product
01. E30.3VG. HR. E.P replacement filter element is produced according to DIN24550 industrial filter standard, and the finished product undergoes multi pass performance sampling. The core technical parameters are as follows:
-Product model: 01.E30.3VG. HR. E.P (domestic substitute)
-Filtering accuracy: 3 μ m, β (c) ≥ 200, absolute filtering grade
-Compatible filter: INTERNORMEN 01.E30 series compact high-pressure filter
-Model code definition: VG=fiberglass filter material; HR=high pollutant carrying capacity structure; E=Single end open end cap; P=NBR nitrile rubber seal

-Maximum collapse pressure difference: 21 bar, able to withstand instantaneous pressure difference impact in high-pressure pipelines
-Working temperature range: -30 ℃ to+105 ℃
-Suggest replacing the pressure difference: 0.22MPa. If the pressure difference reaches the threshold, replace the filter element in a timely manner
-Oil flow direction: from outside to inside, matching the standard flow direction of the high-pressure filter
-Structural form: ultra-fine multi-layer gradient glass fiber folding, thickened metal inner and outer support skeleton
Detailed introduction of product materials
-Filter material: Ultra fine multi-layer gradient resin cured VG fiberglass filter material, HR high dirt absorption design, maximizes effective filtration area in limited shell space. The outer layer intercepts larger particle impurities, while the inner layer achieves precise interception of 3 μm; The filter material is impregnated and solidified at high temperature, and the fibers are tightly bonded. The high-pressure oil flow repeatedly washes the fibers without peeling off, preventing small fibers from wearing the servo valve core. Gradient layered pollution absorption improves the short board of high-precision filter cartridges that are prone to rapid clogging and delays the rise of pressure difference.
-Internal and External Support Skeleton: Thickened punched galvanized carbon steel skeleton, compact reinforced structure, enhanced anti extrusion ability, able to cope with the alternating pressure difference of high-pressure system start stop, and prevent the filter element from collapsing due to suction; The high porosity of the skeleton balances the flow resistance caused by high precision, controls the initial pressure difference, and does not interfere with high-pressure fuel supply.
-Sealing parts: standard NBR nitrile rubber sealing ring, oil resistant and anti-aging, ensuring tight sealing between filter element and filter seat, and avoiding medium bypass short circuit; High temperature and phosphate ester medium working conditions, supporting the upgrade of FKM fluororubber seals.
-End caps and bonding process: machined metal end caps, high-strength two-component adhesive hot pressed composite; The adhesive strength has undergone cyclic differential pressure impact testing and will not peel or crack under high voltage alternating conditions; 1: 1. Reproduce the original factory installation dimensions, with precise disassembly and positioning inside the narrow filter housing.

Main applicable scenarios and industries
01.E30.3VG. HR. E.P positioning compact high-pressure pipeline filter, used for precision servo oil circuit downstream of oil pump, not recommended for return oil filtration.
-Precision metallurgy industry: servo control circuit for rolling mills, protecting servo valves in narrow installation spaces to ensure rolling control accuracy.
-High end machine tool equipment: precision machining center hydraulic servo system, protecting proportional valves and servo valves, reducing valve failure rate.
-Experimental testing equipment: hydraulic test bench, fatigue test bench, high-pressure precision oil purification.
-Power industry: power plant speed control system, control oil station high-voltage precision filtration.
-Industrial complete equipment: domestication replacement of imported high-pressure filtration equipment at space limited locations.
Core advantages of the product
1. Compact HR high dirt absorption structure, small shell with large dirt capacity: Optimized the folding arrangement of filter materials under limited shell size. Compared with ordinary non HR versions, the dirt absorption capacity is significantly increased, relieving the pain point of easy blockage of 3 μ m high-precision filter elements.
2. 3 μm high-precision filtration, guarding expensive servo components: stable β value filtration level, intercepting small hard particles, reducing servo valve jamming and valve core wear, ensuring equipment control accuracy, and reducing downtime maintenance losses.
3. High pressure reinforced structure, resistant to alternating pressure impact: thickened metal skeleton combined with high-pressure grade ultra-fine glass fiber, after pressure difference cyclic impact testing, adapted to frequent start stop pressure fluctuations in industrial sites.
4. Controllable low initial pressure difference, without affecting the servo system response: Optimize the arrangement of filter materials and skeleton openings, control the flow resistance within a reasonable range while ensuring high precision, and do not interfere with the dynamic response of the servo oil circuit.
Core advantages of source factory substitution
Our factory has mature experience in mass production of INTERNORMEN 01. E compact series filter cartridges. We have established strict factory inspections for HR high-precision small shell filter cartridges, and conduct pressure resistance, sealing, and filtration efficiency verification for each batch of samples. We focus on controlling the risk of ultrafine fiber detachment and preventing unqualified products from flowing to precision equipment sites. Direct supply from the source manufacturer, cutting off the premium of imported brand intermediaries, supporting single sample machine testing, undertaking factory maintenance, and bulk procurement of projects; Regular models are in stock and can quickly respond to urgent spare parts orders. Filter materials and seals can be customized and upgraded according to the medium and temperature.
Frequently Asked Questions (FAQ)
Q1: What is the difference between the HR version and the regular 01. E30.3VG. E.P version?
A: HR represents a high pollutant absorption structure, with a larger internal filter material area and stronger pollutant absorption capacity for the same shell size; The external installation dimensions of the two are completely identical and can be interchanged for assembly. HR is more suitable for operating conditions with high system impurities.
Q2: Can this high-precision filter be installed in the return oil pipeline?
A: Not recommended, this model is dedicated to high-voltage servo and has a high cost; The corresponding oil return series filter element should be selected for oil return, taking into account both the effectiveness of use and the procurement cost.
Q3: How to deal with the rapid increase in pressure difference of 3 μm high-precision filter element?
A: High precision filter elements are sensitive to impurities, and a rapid increase in pressure difference indicates a high level of impurities in the system; Suggest adding pre coarse filtration to the front-end, regularly detecting oil contamination, and replacing it promptly when the pressure difference reaches 0.22MPa.
Q4: Apart from INTERNORMEN filter elements, what other oil filtration products do you have?
A: Our factory has a complete product line for oil filtration. In addition to INTERNORMEN replacement filters, we also produce PALL, PARKER, 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.
