Hydraulic Oil Filter Complete Model Quality Reliability Industry Return Filter Cartridge Metal 936 Inlet Oil Filter 53C0291
In hydraulic systems, the return oil filter element plays a crucial role. It is typically installed in the system's return oil line and is used to filter the oil returning to the tank from actuator components such as hydraulic cylinders and motors. Its primary task is to capture wear particles generated internally within the system, fragments of sealing materials, and any tiny contaminants that may have infiltrated from the outside, thereby maintaining the cleanliness of the hydraulic oil and protecting precision components from damage.
In terms of product details, a hydraulic return oil filter element typically consists of several key components: high-quality filter media (such as glass fiber, stainless steel mesh, or special filter paper), a sturdy internal and external support frame (metal or plastic), reliable sealing elements (such as O-rings), and a robust end cap. It is designed with precision and offers a variety of interface types, including threaded connections and flange connections, to accommodate different installation requirements. The filter element has a wide range of filtration accuracy, varying from a few microns to tens of microns, allowing users to choose according to the specific cleanliness requirements of their system.
High-precision filtration: The precision is typically between 1-40μm, with a common range of 5-20μm. The fiberglass material has a βx≥200, with a filtration efficiency of over 99.5%. The stainless steel mesh filter can be reused after cleaning.
Low pressure loss and large flow capacity: The initial pressure loss is usually ≤0.08MPa, with a large flow capacity and a flow range covering from 25L/min to 1300L/min, suitable for various equipment.
Strong environmental resistance: Stainless steel can withstand extreme temperatures ranging from -10℃ to +100℃, boasts high pressure-bearing capacity, and can endure pressure differences up to 21MPa.
Robust and durable structure: It possesses extremely high axial and radial stiffness, capable of withstanding pulsations and hydraulic shocks in the return oil circuit without deforming.
Safety redundancy design: Equipped with a bypass valve (opening pressure approximately 0.4 MPa) and a differential pressure transmitter (alarm pressure approximately 0.35 MPa). When the filter element becomes clogged, the transmitter will first trigger an alarm. If it is not replaced in time, the bypass valve will open to protect the system.
Convenient and quick maintenance: The direct return design makes replacing the filter element as simple as changing a screw cap. Some dual-cylinder models also allow for filter element replacement without stopping the machine. At the same time, the bottom diffuser design enables smooth oil return, avoiding the generation of bubbles and agitating sediment at the bottom of the oil tank
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.
