Tips to choose the filter element and tips to install filter element

In this article, we will introduce some tips to help you choose the filter element and find you the best way to install the filter element.

5 Tips to choose filter element

Firstly, let us figure out how to choose a suitable filter cartridge for your industry. Based on the characteristics of cartridges and industries, we summarize 5 tips for you.

Tip 1: According to the filtered objects, the cartridge filters can be divided into liquid filtration and gas filtration, and its size is normally 5 “, 10 “, 20”, 30, and 40 “, etc. Because the pore size of the filter element is different, the flow rate is not the same.

For example, if the pore size of the filter element is 0.2um — 0.4um ,then it can filter the turbid water 300-500kg /h. Multi-core or combination of 20 “, 30 “and 40” can be applied to improve the filtration capacity per hour.

Tip 2: To get a suitable filter element, you should select the appropriate pore size. If you want to sterilize, choosing the pore size of the 0.2um-0.5um filter element is better, during the production of medicinal injections, antibiotics, blood products, etc.

If you want to remove particles, microorganisms, and bacteria during the filtration of white wine, beer, wine, and oral liquid, then you can choose the pore size of 1~5um. To filter high-temperature gas and fermentation air, disinfection gas , we are suggested to choose a Teflon filter cartridge.


Tip 3: To achieve the purpose of fine filtration, the pre-filtration device must be utilized in the previous stage, and then using absolute rating sterilizing filter elements, such as Bromen pleated cartridge filter and ELC pleated cartridge filter.

For the filtration of mineral water or sterile water for medical usage

Tip 4: For the filtration of mineral water or sterile water for medical usage, electric condensate water and high quality water for food industry, the cartridge filter should be designed as an independent filtration system, which can be back flush to save maintenance costs.

Top 5: When using stainless steel filter housing, pay attention to whether the filtered liquids has corrosion effect on stainless steel. If the stainless steel can not withstand the affect, filter housing of other materials should be selected.

7 tips to install filter element

After learning how to pick up the filter element, let’s move on to the installation now. The following are useful and helpful tips for you to install a filter element.

Base installation

We need to have a look at the inlet and outlet direction before base installation. The liquid should flow from outside the filter housing into the center. The pipe connected with the body of the filter housing is the outlet. The flow direction is indicated by arrows on the filter pipe. It should be noticed that don’t make the wrong connection.

Filter element installation

The 222 socket is for insertion type; The socket of 226 is snap-in type. If it is a multi-core type, the pressing plate should be set on the fin and the moderate tightening of the inner hole.

Check the Seal

Install the outer shell and base with a clamp (single core) or female (multi-core) connection sealed, double-check the seal, and make sure no leakage.

Filter disinfection

Filter disinfection

The new filter must be cleaned before use. The sanitary filter used for sterilization should be sterilized and disinfected, and the disinfection work should be carried out in the production line to avoid external contamination.

Open the exhaust valve

When filtering liquid, we should first open the exhaust valve at the top of the filter, let the gas in the cylinder out, and let the liquid fill the cylinder, otherwise, it will affect the flow.

Pressure drop

The process of liquid flowing through the filter media will produce a pressure drop (that is, the pressure difference between in and out) due to resistance. To overcome this resistance and keep the consistent flow, it is necessary to have enough operating pressure. We have given the corresponding temperature and pressure valve for each filter element. In order not to make the filter element by the impact of excessive flow. Be sure to open the valve slowly!

Release the filtrate

The filtrate should be released when stopping the machine. If the time is not too long, it is unnecessary to open the filter. If the time is relatively long, or the filtrate is not suitable for staying for a long time, it is essential to clean the filter or filter element.


No matter choosing the filter element or installing the filter element, there are many details you should pay attention to. Only when you have good knowledge about all this information, you can improve your filtration performance with the most suitable filter element.
