How to choose the correct replacement filter element

The filter element plays a vital role in the filtration system. The quality of the filter element is directly related to the effect of the filter. For a good filter, the cost of the filter element also occupies a large share. In the past, due to the excellent technology of foreign filter element brands, foreign filter elements were generally selected for high-efficiency and precision filters. But the price is relatively high, and now the technical indicators of domestic filter elements have basically reached the level of foreign countries, and the price advantage is relatively clear, so how to replace the filter element with a more cost-effective filter, the following steps will teach you:

1. Obtain the detailed information of the customer's original filter element, especially the material applicability and structural characteristics:

If the user wants to replace the filter element, in addition to understanding the performance of the filter itself, he must also have a full understanding of the information of the original filter element. The most important thing is the applicability of the material and the characteristics of the filter element structure. The material of the filter element is various, and different materials have different technical indicators such as service life and filtration efficiency, and the structural characteristics of the filter element are important indicators to match the filter body. If you use an alternative filter element, you must fully understand the above two points to avoid choosing the wrong filter element and causing major problems in the safety and effectiveness of the filter.

Second, carry out the actual test of various performance indicators on the selected alternative filter element

Although we can get specific information from the manufacturer about the performance of the replacement filter element, whether it is applicable to all our filters at the same time is a personal inspection process. For the appearance and physical structure of the filter element, such as the structural size, you can generally use simple tools to obtain it conveniently. For the professional performance of the filter element such as the actual filtration accuracy, initial pressure difference, and dirt-holding capacity, it is generally recommended that customers go to a professional filter element manufacturer. , Use professional testing equipment for on-site inspection.

3. Check the cleanliness of the filter media

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 system target cleanliness requirements by detecting the contamination of the system medium.
