307.5 Hydraulic Return Filter Element For Excavator Replacement 304-7195
In the operation of construction machinery, the stability of the hydraulic system directly determines the service life and operational efficiency of the equipment. The hydraulic return oil filter is one of the core components that protect this system. Its main function is to filter the hydraulic oil returning from the actuator to the oil tank, remove metal particles, dust, and aged sludge and other pollutants, and prevent impurities from entering the pump and valve body again, causing wear or blockage. Especially in high load equipment such as excavators, the cleanliness of hydraulic oil directly affects the accuracy of movement and the cooling effect of the system.
If the performance of the filter element is insufficient, it can lead to slow operation in mild cases and damage to the hydraulic pump in severe cases, resulting in high maintenance costs. Therefore, choosing a matching and efficient return oil filter is a crucial step in ensuring the long-term stable operation of the equipment.
The hydraulic return oil filter element adopts high-strength composite materials, such as the multi-layer composite process of stainless steel woven mesh and fiberglass/synthetic filter material. This design significantly improves the axial flattening stiffness of the filter element, allowing it to maintain zero deformation even under extreme pressure.
In the manufacturing process of hydraulic return oil filter element, nanoscale gradient filtration technology is applied to achieve a filtering effect with minimal surface uniformity error, and has a high interception rate for larger particles. The production process strictly adheres to the certification standards of the International Organization for Standardization (ISO), ensuring the reliability of the filter cartridge throughout its lifecycle.
The hydraulic return oil filter element has been deeply adapted for different industrial scenarios. We have developed special filter cartridges for heavy-duty fields such as steel rolling mills and continuous casting production lines to solve the sealing problem under high-pressure water-based media; A corrosion-resistant galvanized end cap model has been designed to resist corrosion from sulfur-containing gases for extreme working conditions such as well injection operations in desert oil fields. These adaptive designs significantly improve the performance of the filter element in specific industrial scenarios.
The hydraulic return oil filter element also performs well in terms of economy and environmental benefits. According to different operating conditions, the filter element provides a classification scheme, such as washable and disposable, to reduce annual maintenance costs and total cost of ownership (TCO). The recycling and regeneration project of filter cartridges has established a complete closed loop. After special treatment, waste filter materials can be remade into other products, achieving the recycling of resources and a significant reduction in carbon footprint.

Q1.Do you have MOQ?
Depends on different ideas, Can be negotiated.The larger the quantity is, the competitive the unit price will be.
Q2.Should the customer pay the delivery fee,How much is it?
For the delivery fee,many samples are be requested to be sent,so we must get delivery fee. If you tell me to use the appointed Express,you will give me your express account or you will pay according to the Express. If you do not request,I will choose a cheap one in China.
Q3.How about the after sale service?
1)We will always keep the quality the same as the buyer's samples and if there is something with the quality,we will make compensation for our customers.
2)We will suggest our packing and take charge in our packing,we will keep the goods safe in the delivery.
3)We will trace the goods from the production to selling,we will solve the problems in the selling for our customers.
Q4.When can I get a price?
We usually quote within 24 hours after we get your inquiry.
Q5: What are the materials of the filter element? What are the corresponding accuracy ranges?
According to the classification of filter materials, there are: oil filter paper: 10-50um, glass fiber: 1-70um, HV glass fiber: 3-40um, metal mesh: 3-500um, sintered felt: 5-70um, and line gap filter: 15-200um.
Q6: What brands of filter cartridges do you make?
Our factory produces alternative universal filter elements for foreign brands such as Pall, Hedek, Dasheng, Parker, and Rexroth, as well as national standard oil suction filter elements, oil return filter elements, high-pressure filter elements, and coalescence dehydration filter elements. We support non-standard customization. We welcome samples or drawings for processing and customization.
Q7: How can customers choose the appropriate filter size when making their own filters?
We need to provide the flow rate, pressure, external dimensions, accuracy, filter medium and other parameters of the filter designed by the customer. We will provide the customer with the selected filter element size and quantity based on the filter size.
Q8: Is there any difference between filtering kerosene, gasoline, diesel filters and general hydraulic oil filters?
The sealing materials used in the filter element are different. Generally, the sealing ring of hydraulic oil filter element is nitrile rubber, while filtering media such as kerosene, gasoline, and diesel requires the use of fluorine rubber rings.
