HYDAC 0240R010BN4HC replaces hydraulic oil filter element for high-pressure return oil filtration

Description :

  This industrial hydraulic oil filter element is a precision filter element designed specifically for hydraulic systems, mainly used to replace the 0240R010BN4HC model of the HYDAC brand from Hedec. It can effectively intercept metal particles, rubber impurities, and oxides in hydraulic oil, solving problems such as valve core sticking and pump body wear caused by oil pollution. This filter element is typically used in the return or pressure pipelines of medium and high pressure hydraulic systems such as construction machinery, injection molding machines, and die-casting machines, ensuring that the cleanliness of the system oil meets NAS 1638 or ISO 4406 standard levels, extending the service life of hydraulic components, and ensuring continuous and stable operation of equipment.

  The hydraulic oil filter element adopts multi-layer glass fiber filter material, with a filtration accuracy of usually 10 microns (corresponding to 010 in the model), and has a high dirt holding capacity and low initial pressure difference. The filter frame is supported by high-strength galvanized steel pipes or stainless steel mesh, which can withstand working pressures up to 21MPa or even higher without deformation or rupture. End caps are usually made of carbon steel material, treated with rust prevention, and sealed with oil resistant nitrile rubber or fluororubber. They are suitable for working temperatures ranging from -30 ℃ to 100 ℃. The product structure design complies with international universal standards, with strict control of dimensional tolerances to ensure a perfect match with the original Hedeke filter seat and no risk of leakage.

  When selecting, it is necessary to confirm whether the filter element model used in the original equipment is the 0240R series, and verify the interface thread specifications and installation dimensions. This 0240R010BN4HC replacement filter is suitable for common hydraulic media such as mineral oil and water ethylene glycol, but is not recommended for use in strong acid, strong alkali, or special synthetic ester oil environments unless customized with special material filter materials. If the working conditions experience significant vibration or frequent impact pressure, it is recommended to choose a version with a bypass valve design to prevent filter cartridge breakdown. Compared with ordinary oil suction filters, this type of high-pressure return filter requires higher pressure resistance and filtration efficiency, and cannot be mixed. When purchasing, it is necessary to clearly distinguish the installation position and pressure level.

  Before installing the hydraulic oil filter element, it is necessary to clean the inside of the filter element seat and check whether the sealing ring is intact to avoid leakage caused by residual old seals. It is recommended to replace it every 2000 hours of work or when the differential pressure indicator alarms, depending on the degree of oil contamination on site. During daily maintenance, the cleanliness of hydraulic oil should be regularly checked. If a large amount of metal shavings are found attached to the surface of the filter element, it may indicate wear and tear on the pump or motor, and further investigation of the fault source is needed. When replacing, it is strictly prohibited to strike the filter cartridge housing. A special wrench should be used to tighten it with moderate torque to prevent damage to the threads or sealing surfaces, ensuring good system sealing and maintaining efficient operation of the hydraulic system.
