Note:
1. The filtering efficiency with initial precision is N=95%
2. The filtration efficiency of the largest particle is N=99%
3. The precision of the filter element gradually increases during cyclic filtration
4. This flow rate value is the flow rate value of each nominal accuracy when filtering water with a 10 "standard filter element under a pressure difference of P=0.015MPa.
4 Filter cartridge model description:
⑴ Classification of filter cartridges
Filter cartridges are divided into three categories: general type (VP, referring to household water purifier filter cartridges with average lifespan, etc.), high-efficiency type (AP, referring to engineering filter cartridges with high flow rate and long lifespan, etc.), and special type (TP, referring to filter cartridges used in special occasions or with special requirements).
⑵ Model representation method
The model is composed of product series classification, precision, specifications, and other types.
Selection of 5 filter cartridges:
In addition to technical indicators such as length, inner diameter, outer diameter, connection method, sealing form, and compatibility with the filtered medium, the filter element also has necessary technical parameters such as accuracy, retention rate, flow rate, and pollutant holding capacity. It is these completely independent technical indicators that form the inherent quality of the filter element. Only by selecting a filter element that meets all these indicators can it be used well, and with a reasonable selection of the number of elements, it is even more economical.
The nominal accuracy exists with the assistance of interception rate, and there is no standard recognized and followed by all industry players. That is to say, for the same 5 μ m product, Company A can set the retention rate at 85-95%, while Company B can set it at 50-70%, as you please. In other words, Company A's 25 μ m filtering accuracy may be equal to Company B's 5 μ m or finer. Even though the two filters shown in the figure have the same filtering ability of 95% for 5 μ m particles, their filtering functions do have significant differences. Therefore, the best solution is to "try it out", and our company is willing to use our experience to assist you in the selection of filter cartridges.
