Detailed introduction of product materials

CS-150-A10-A is an integrated rotary oil return filter element, with a complete set of housing, filter material, and seal integrated. It can be disassembled and replaced directly by screwing, with a focus on avoiding problems such as insufficient pressure resistance of low-priced substitute housing, flat filter material suction, end cap detachment, and thread fit deviation in the market.

-Filter material: Multi layer gradient resin cured inorganic fiberglass filter material, increasing the total folding area of the filter material, suitable for 150L/min level high flow oil return conditions. The outer layer prioritizes the interception of large abrasive particles and oil sludge, while the inner layer achieves precise interception of 10 μ m; The filter material is impregnated and solidified at high temperature, and the fibers are firmly bonded. It will not peel off under repeated impact of the return oil flow, avoiding small fibers from entering the oil tank and causing secondary circulation pollution. Gradient layered pollution control design, where impurities are trapped in different filter layers, delaying pressure rise and reducing on-site replacement frequency.

-Internal and external support mesh: Thickened galvanized carbon steel punching mesh, with bidirectional support inside and outside, enhances the overall anti extrusion ability, responds to the flow impact and instantaneous negative pressure caused by the start and stop of the return oil pipeline, and prevents the filter element from being flattened and collapsed by the oil flow. The high porosity design of the protective net ensures high flux flow, reduces the initial pressure difference of the filter element, and does not add additional resistance to the hydraulic return oil circulation.

-Sealing parts: the end is integrated with NBR nitrile rubber sealing ring, which is oil resistant, anti-aging, and resistant to medium swelling; After tightening, the sealing ring should be tightly pressed against the cover to prevent oil bypass short circuits. High temperature and special flame retardant medium working conditions, supporting the upgrade of FKM fluororubber seals.

-Shell and threaded end cap: The rotary assembly adopts cold-rolled steel plate stamping shell, and the end cap thread strictly replicates the original factory tolerance. The thread fit is smooth, and there will be no assembly problems such as improper tightening or thread slippage; The internal filter material and end cap are bonded using high-strength hot pressing technology, which will not peel or crack in environments with frequent flow fluctuations.

Main applicable scenarios and industries

CS-150-A10-A positioning rotary high flow return oil filter, installed in the front return oil pipeline of the return oil tank, is not recommended for direct use in high-pressure oil circuits.

-Construction Machinery Industry: Pump trucks, vehicle mounted hydraulic equipment, small and medium-sized mobile hydraulic station return oil filtration, rotary structure for easy disassembly and assembly, suitable for quick on-site maintenance.

-Rubber and plastic machinery industry: hydraulic station oil purification for small and medium-sized injection molding machines and extrusion equipment.

-General industrial hydraulics: various small and medium-sized hydraulic stations, hydraulic testing equipment return oil filtration.

-Metallurgical auxiliary equipment industry: Purification of return oil pipelines for auxiliary hydraulic systems of small and medium-sized rolling mills.

-Mining light industry equipment: compact space equipment that pursues simple and fast replacement of filter elements.

Core advantages of the product

1. Integrated rotary structure, simple and efficient disassembly and maintenance: The entire filter cartridge assembly does not require disassembly of the filter housing, and can be directly screwed and disassembled, greatly reducing on-site replacement time and suitable for outdoor and compact equipment working conditions.

2. High flow fiberglass filter material, specially optimized for oil return: designed for 150L/min level oil return conditions, with low initial pressure difference to ensure smooth oil return circulation, and a 10 μ m accuracy that balances interception capability and pollutant absorption performance.

3. Double directional protective net reinforcement structure, anti negative pressure suction flat: The inner and outer metal protective nets withstand the instantaneous negative pressure impact of oil return start stop, reducing the risk of filter deformation and failure.

4. Pre purification of oil return to reduce the load on the entire system: intercept impurities before the oil returns to the tank, reduce the accumulation of sediment in the tank, and indirectly protect the oil pump, valves, and downstream precision filter elements.

Core advantages of source factory substitution

Our factory has mature production experience in the MP-FILTRI CS rotary filter series. We have established a special factory inspection process for the CS-150 high flow rotary filter cartridge, and conduct shell pressure resistance, thread tolerance verification, sealing, and filtration efficiency tests on each batch of samples to control the risks of thread slippage, shell bulging, and fiber detachment, ensuring the reliability of machine assembly. Direct supply from the source manufacturer, cutting down the premium of multi-layer intermediaries for imported brands. It not only supports single sample machine testing, but also undertakes annual factory maintenance and large-scale bidding procurement for engineering projects. We can customize and upgrade the sealing material according to the customer's on-site medium and temperature conditions. 

Frequently Asked Questions (FAQ)

Q1: What are the assembly tips when installing a rotary filter cartridge?

A: Wipe the sealing surface clean before installation, apply a small amount of hydraulic oil to the O-ring, tighten it by hand and then use a wrench to turn it 1-1.5 times. Do not use excessive force to tighten, to avoid thread damage and shell deformation.

Q2: What is the main reason for the rapid increase in filter pressure difference in a short period of time?

A: Most of them are due to the high total amount of pollutants inside the system, or the oxidation of oil to generate a large amount of oil sludge colloids; It is recommended to synchronously detect the degree of oil contamination and check whether there is abnormal wear on the equipment. If the pressure difference reaches 0.2 MPa, the filter element needs to be replaced in a timely manner.

Q3: What is the function of the built-in bypass valve when installing the oil filter?

A: When the filter element is clogged and the pressure difference exceeds the set value, the bypass valve opens, and the oil flows directly back to the oil tank without passing through the filter element, avoiding pressure build-up in the return oil; The opening of the bypass valve indicates that the filter element has failed and needs to be replaced as soon as possible. It is not advisable to rely on the bypass valve for long-term operation.

Q4: Apart from MP‑FILTRI filter elements, what other oil filtration products do you have?

A: Our factory has a complete product line for oil filtration. In addition to MP‑FILTRI 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.
