The filter element separates the solid particles in the liquid or gas, or makes full contact with different material components to speed up the reaction time, which can protect the normal operation of the equipment or the cleanness of the air. When the fluid enters the filter element with a certain size of filter, its impurities are blocked , And the clean fluid flows out through the filter element. The liquid filter element allows the liquid (including oil, water, etc.) to clean the contaminated liquid to the state required for production and life, that is, to achieve a certain degree of cleanliness.

Foldable microporous filter
The foldable microporous filter element adopts polypropylene (Polypropylene) thermal spray fiber membrane, nylon (Nylonb) polytetrafluoroethylene (PTEE) microporous filter membrane and other precision filter devices made of filter media. It has a small volume and a large filter area. High precision and other advantages. Filtration accuracy can range from 0.1μm to 60μm. The sealing of the end cover of the filter element and the connection of the whole structure are all hot melt adhesive. The filter element joints are three types commonly used internationally: 222 joints, 226 joints, and flat ports. The products undergo strict and complete testing before leaving the factory to ensure the stable performance of the products.

Resin is a porous, insoluble exchange material. Thousands of fine plastic balls (beads) are installed in the resin filter element of the water softener. All small balls contain many negative charge exchange sites that absorb positive ions. When the resin is in a nascent state, these charge exchange sites are occupied by positively charged sodium ions. When calcium and magnesium pass through the resin storage tank, they come into contact with the resin beads to replace sodium ions from the exchange site. The resin preferentially binds cations with a stronger charge, and calcium and magnesium ions have a stronger charge than sodium ions. Instead of sodium cations, they pass through the resin bed and flow out of the water softener, so that the water softener sends out "soft" water. Finally, all resin exchange positions are occupied by calcium and magnesium, and can no longer work.
Stainless steel filter
Stainless steel filter (Stainless Steel filter), has a good and good filtration performance, can play a uniform surface filtration performance for the filtration particle size of 2-200μm, the main filter material uses multi-layer stainless steel sintered mesh, the filtration accuracy is 0.5-200μm, Its external dimensions can be processed according to user requirements.
Features of stainless steel filter:
1. Good filtration performance, uniform filtration performance on 2-200μm filtration particle size;
2. Good corrosion resistance, heat resistance, pressure resistance and wear resistance;
3. The pores of the stainless steel filter element are uniform and precise in filtration accuracy;
4. The flow rate per unit area of the stainless steel filter element is large;
5. The stainless steel filter element is suitable for low temperature and high temperature environments; it can be used again after cleaning without replacement.
Household water purifier filter is not the better
At present, some low-end water purifiers on the market are equipped with four or five filter elements or even more, but if simple filter materials are used, the filtering effect may not be equal to a high-performance filter element. Therefore, in the specific purchase process, consumers do not need to believe in the number of filter elements, but should pay more attention to the performance of the filter element itself, and understand and check whether the last filter uses a disposable filter element, if so, it can be better Avoid secondary pollution.
As for the claim that the filter element does not need to be replaced in 3 to 5 years, consumers can keep an eye on it, because this is often a bit exaggerated. The reason is very simple, after all, the filter element that will block is the good filter element, it just shows that there is a certain filtering effect. On the whole, the higher the quality of the filter element, the better the effect, so that not only the water purification is guaranteed, but also the service life will be longer.
