Detailed introduction of product materials
0240D003BH3HC requires dual performance of 3 μm high precision and high pressure impact resistance, and all materials are benchmarked against the original BH3HC high pressure filter material standard:
-Filter material: High pressure multi-layer gradient resin bonded glass fiber, with an outer layer pre filtering to intercept large particle pollutants, and an inner layer achieving 3 μ m precision filtration; The filter material adopts high-pressure strengthening and solidification process, which ensures that the filter material does not crack, break or lose fibers under the repeated action of high-pressure pulses, balancing high precision and high-pressure structural strength.
-Internal and External Skeleton: Thickened high-strength punched metal skeleton enhances the anti extrusion ability for high-precision high-pressure working conditions, resists high-pressure differentials, and prevents filter element flattening, deformation, and failure.
-Sealing rubber ring: standard NBR nitrile rubber sealing ring, reliable sealing under high pressure conditions, preventing high-pressure oil leakage and air intake; FKM fluororubber seals can be replaced for high temperature special working conditions.
-End cap structure: thickened metal end cap, high-pressure special hot pressing composite bonding process, high bonding strength between filter material and end cap, no delamination due to high-pressure fluid impact, installation and positioning dimensions are completely consistent with the original.

Core advantages of the product
1. Dual performance of high pressure and 3 μm high precision: Simultaneously achieving 3 μm precision filtration under 21MPa high pressure conditions, it can withstand pressure pulse impact and capture micro particles, protecting expensive servo valve components.
2. Gradient pollution absorption structure to alleviate the clogging problem caused by high precision: Multi layer composite filter materials layer by layer contain pollutants, which improves the service life compared to single-layer high-precision filter materials.
3. Strengthen the overall structure of high pressure and avoid the risk of high pressure failure: The skeleton and end cap bonding processes are optimized for high pressure and high precision working conditions to reduce filter material breakage, delamination, and flattening failures.
4. Directly replace imported components in situ: The size interface is 100% compatible with the original high-pressure filter, and on-site disassembly is simple without the need to modify the high-pressure pipeline.
5. The filter material has no fiber shedding, avoiding secondary pollution of the oil circuit: high-pressure cured fiberglass, oil flow cannot wash away fibers, and does not introduce new impurities into the precision high-pressure system.
Core advantages of source factory substitution
For high-precision high-pressure filter elements, our factory implements higher factory inspection standards than ordinary filter elements to avoid significant equipment losses caused by failure under high-pressure conditions:
-Reproduction of the original BH high-pressure filter material process, special pulse withstand voltage test: Referring to the HYDAC D series technical manual, each batch is sampled for withstand voltage and pulse pressure difference testing, in accordance with ISO2941 standard, while verifying the 3 μ m filtration efficiency, balancing accuracy and high-pressure strength.
-Direct supply from the source factory, reducing the cost of precision high-voltage components: no brand premium, procurement cost far lower than original imported parts, suitable for equipment maintenance and batch matching of projects.
-Strict full process quality control, traceable quality: filter material incoming inspection, production process control, finished product sampling and testing, high-pressure high-precision filter cartridges can provide testing records as needed.
-Support customized working conditions: materials can be customized for high temperatures and special media.
Frequently asked questions
Q1: Can this 0240D003BH3HC directly replace the original HYDAC?
A: Can be directly replaced, with size, sealing, 3 μm filtration accuracy, and high-pressure anti pulse performance compared to the original, compatible with the 0240 specification DF series high-pressure filter, used for the front end of the pump outlet servo valve.
Q2: Will the 3 μm high-pressure filter be easily clogged?
A: Adopting a gradient multi-layer filter material structure, layer by layer dirt collection, the normal clean system will not quickly clog; Severe system pollution will accelerate the rise of pressure difference, and a replacement standard of 0.5MPa pressure difference will be used.
Q3: Can this high-pressure filter element be used in the return oil filter?
A: Physical installation is possible, but not recommended. The cost of high-pressure and high-precision filter cartridges is high, and the dirt absorption design is targeted at pressure pipelines. R series return oil filter cartridges are preferred for return oil scenarios.
Q4: What are the main reasons for the damage of the filter material in high-pressure and high-precision filter cartridges?
A: Most of them are caused by instantaneous overpressure in the system or excessive pressure difference due to the accumulation of pollutants. They should be replaced strictly according to the pressure difference prompts and the source of pressure shock in the system should be investigated.
Q5: What other oil filtration products do you have besides Hedeke filter cartridges?
A: Our factory has a complete product line for oil filtration. In addition to HYDAC 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.
