Why Alternative Filter Elements Are Necessary
The solid particle pollutants are harmful seriously to the hydraulic and lubrication system. Each hydraulic and lubrication system has its own minimum requirement for the pollutant content in the oil, that is, the target cleanliness of the system. When the content of solid particle pollutants is lower than the target cleanliness of the system, the system runs normally and well, but once it is higher than the target cleanliness of the system, the working performance, working reliability and working life of the system will be affected.
Due to the external intrusion & the internal generation, there are a lot of solid particle pollutants increased unavoidably during the running process of the hydraulic system. Therefore, the hydraulic system must continuously remove solid particle contaminants in order to achieve the target cleanliness, which will be done by the filter element.
The filter element(filter cartridge) is a filter component which made of porous filter material. It intercepts the solid particles in the medium through surface interception and curved hole adsorption, so as to achieve the purpose of purifying the medium. At the same time, the retained solid particles block the medium channel of the filter element, which increases the pressure difference at both ends of the filter element. When the pressure difference across the filter element reaches its limit, the filter element cannot continue to work and needs to be replaced with new one. It can be seen that the filter element is a consumable part in the system.
In an era where high-end, industrial-grade equipment dominates, it’s easy to find ourselves relying on international brands like Pall, Parker, Hydac, EPE, MAHLE, ARGO, STAUFF, and INTERNORMAN, especially when it comes to crucial components like filter elements.
In today’s fast-paced industrial world, the upkeep and maintenance of large-scale metallurgical equipment can be a costly endeavor. Particularly, the regular replacement of filter elements, a key consumable component, often leads to significant expenses due to the high costs associated with original branded filters.
However, there is a cost-effective solution that doesn’t compromise on performance – our domestically-produced, high-quality filter elements. We understand that in a world of ever-increasing operating expenses, most users are looking for ways to save on their running costs. Our product is designed with this need in mind.

Our filter elements are not only cost-effective but also boast of the same technical parameters, performance, and working lifespan as those of renowned international brands like Pall, Parker, Hydac, EPE, MAHLE, ARGO, STAUFF, and INTERNORMAN. The result? You can enjoy top-tier performance without the top-tier price tag, significantly reducing your operating costs.
Moreover, for equipment that has been in service for many years, finding matching original brand elements for continued operation can be a challenge. In some cases, the original filters might not even be available. Our product addresses this issue head-on. With our versatile range of replacement filter elements, you’ll never have to worry about finding a matching filter for your aging equipment.
We aim to solve these problems and more. Switch to our domestically-produced filter elements. Embrace the perfect blend of affordability, performance, and longevity. It’s time to redefine cost-efficiency in your industrial operations.
How to Select the Perfect Filter Element Alternative
a, Check the cleanliness status of the medium
The target cleanliness of the hydraulic and lubrication system is given by the manufacturer of the equipment, which could be got from the original technical docs of the equipment. When using the original filter element to maintain the cleanliness of the system, the user can check whether the original filter element can meet the target cleanliness requirements of the system by detecting the pollution degree of the system medium.If the cleanliness of the system is qualified, the reasons need to be analyzed. If the performance parameters of the original filter element are too poor to reach the target cleanliness of the system, it is necessary to discuss with the alternative filter element manufacturer to improve the performance parameters of the alternative filter element. In short, the use of alternative filter elements must ensure the target cleanliness of the system
b. The details of original filter element had to be provided
In order to use the qualified replacement filter element, the detailed information of the original filter element had to be provided, as well as a new or old original filter element. In this way, the manufacturers of replacement filter can fully understand and master the performance parameters and size parameters of the original filter, so as to obtain satisfactory replacement filter.
Here the technical data related to the filter element has been listed in Sheet 1 for your reference.

c.Check alternative filter element
The filter element alternatives should be inspected comprehensively to confirm whether it meets the requirements after the detailed information about the original filter element being provided. Generally speaking, the appearance quality and structural size of the filter element can be easily judged by observation and trial installation, but the performance parameters like filter accuracy, pollutant holding capacity, starting pressure difference must be tested as per corresponding inspection standards. Thus, corresponding testing results for such alternative product had to be supplied by the manufacturer, or can be inspected by user themselves or TPI. Of course, users can also judge the quality of the replacement filter element by detecting the cleanliness of the system after the replacement filter element putting into use.
