During the injection, processing, blending, and storage of hydraulic fluids, various pollutants such as particles and moisture may be mixed in, and the degree of contamination often exceeds the requirements specified for actual hydraulic system fluids. The mobile oil filter can prevent impurities from entering the hydraulic system through an efficient filtration system, reduce system wear and failure, and improve system reliability and stability.

Equipment Overview:
Mobile oil filters are used in hydraulic lubrication systems in various industries to filter out solid particles in the oil, extend the service life of hydraulic components, and have high precision and low noise. They are wrapped in a refined shell to cover all components. The internal filter element of the filter can achieve different precision filtration effects according to user selection and requirements, and is easy to use and maintain.
Performance characteristics:
Pressure gauge
It can continuously indicate the operating status of the system and the degree of contamination of the filter element during work, monitor the working status of the oil filter, and have low operating costs.

Protective device
The use of high-pressure pipeline overflow protection device and thermal relay protection can effectively protect the safety of the hydraulic system and prevent motor damage caused by motor overload.

Quick-release structure
The oil filter housing adopts a quick opening structure, which can quickly and efficiently open the upper cover and replace the filter element. The structure is simple, novel and reasonable.

High definition cleanliness
There are two-stage fine filters installed after the pump to quickly achieve a high level of cleanliness in the oil. Different filtration levels can be selected according to specific working conditions to quickly achieve high cleanliness of the oil.

Service life
The coarse filter at the oil suction port protects the oil pump and extends the service life of the main filter. It is an ideal device for pre filtering, injecting oil into the system, and purifying system fluids.


Application areas:
Applied in hydraulic systems and lubrication systems in the steel metallurgy industry, power industry, and paper industry, they can
be used for filtering new oil; Add new oil and filter it; Purification of oil in use; Bypass filtration during hydraulic lubrication
system operation; Remove moisture from the system oil.
As one of the important components of Lefeldt's 150 project departments, the Oil Purification Project Department mainly
produces nationalstandard filters, filter element series, interchangeable imported filters, filter element series, oil filter truck
series, hydraulic equipment such as filters, and filtration monitoring equipment. In the production process, ISO, DIN, IDF,
and 3A industrial standards are strictly followed for manufacturing, with quality meeting GMP standards, stable
performance, and reliable quality.
