There are many factors to consider when choosing the right type of air shower for your needs. Some of the most important factors include the size of the space you have available, the type of contaminants you need to remove, and the frequency of use.
Size is an important consideration because air showers come in a range of sizes. If you have a small space, you will need to choose a smaller air shower. The type of contaminants you need to remove will also affect the size of the air shower you need. If you are removing very fine particles, you will need a larger air shower.
The frequency of use is another important factor to consider. If you are using the air shower infrequently, you can choose a less powerful model. However, if you are using the air shower on a regular basis, you will need a more powerful model that can handle the increased use.
There are many factors to consider when choosing a suitable type of FFU for your needs.
The first is the size of the unit. Size is an important consideration because the larger the space, the more powerful the FFU will need to be. If you are trying to filter a large space, you will need an FFU with a high CADR (clean air delivery rate).
The second is the type of filter. such as the level of contamination in the air, and the type of contaminants that need to be removed. The most common types of filters are HEPA and activated carbon filters. Make sure to choose an FFU that has the right type of filter for your needs.
The third is the noise level. Some FFUs can be quite loud, so make sure to choose one that is suitable for your needs.
The type of contaminants you are trying to remove is also an important consideration. Some Fan Filter Units are designed to remove particulates, while others are designed to remove gases and chemicals. If you are trying to remove a specific type of contaminant, you will need to choose an FFU that is specifically designed to remove that type of contaminant.
By taking all of these factors into consideration, you can narrow down the field and choose the right type of FFU most suitable for your requirements.

The filter cartridge is the core filter component of the liquid filter housing. Generally, the filter cartridges need to be replaced in time when they are deformed or damaged or when the liquid filter fails to meet the water outlet requirements.
Please refer to the replacement steps as follows:
1. Stop the filter and remove the manhole cover;
2. Unscrew the compression nut of the filter housing, remove the pressure plate, take out the filter cartridge, and then rinse the inside of the equipment with water;
3. Remove the upper and lower positioning rings at both ends of the filter cartridge, clean it with water, and then insert the two ends of the new filter cartridge respectively. It should be noted that before any new filter cartridges are used, they must be soaked for about half an hour to keep they are in a wet state;
4. Insert the end of the new filter cartridge with the lower positioning ring into the hole of the perforated plate;
5. Take the tie rod as the axis, put it into the pressure plate, insert the upper positioning ring of the filter cartridge into the corresponding pressure plate hole, and tighten the compression nut;
6. After the filter cartridge is installed, install the manhole cover and turn on the water;
7. Finally, open the water inlet valve and the exhaust valve. When the water is full of the equipment, open the clean valve, close the exhaust valve, and observe the water outlet from the clean outlet. After the water is free of foam, it can be put into normal operation.
It is recommended that you replace the filter cartridge when any of the following situations occurs:
1. The filter cartridge fails the integrity test;
2. The pressure difference reaches more than 2bar;
3. The flow rate does not meet the production requirements
4. Has reached a proven service life
5. The filter element is deformed or damaged;
6. When the filtration accuracy of the filter cartridge is reduced, the water effluent requirements cannot be met;
7. The water output of the system is not up to standard requirements,etc.
After production, thorough cleaning of the filter element can minimize the physical blockage of the filter membrane and is also a requirement for preservation or integrity testing of the filter element after production. For aqueous and organic solvent filter elements, the recommended cleaning methods are as follows:
1. Soak the filter element with 1% NaOH solution (30-60°C) for 2 hours, and wash it with pure water. However, Hybrid Cellulose Membrane Cartridges are not suitable.
2. Acid: soak the filter element in 0.5% HCI solution for 10 minutes, and rinse it with pure water.
1. The filter element shall not be reversely flushed to prevent deformation under pressure;
2. Avoid being damaged by other objects during cleaning;
3. The filter element should be cleaned with high-quality water;
4. It is recommended that the general cleaning temperature be 30-60°C; the soaking cleaning time is 30-60 minutes;
5. After cleaning, the cleaning agent should be thoroughly washed;
6. If you want to use special cleaning agents or special cleaning conditions, please contact Jielv filter.
1. Characteristics of filter media
The filter membrane material is selected according to the characteristics of the liquid or gas. Generally, a hydrophilic membrane is used to filter an aqueous solution, and a hydrophobic membrane can be used to filter an organic solvent.
2. Filtered processing volume.
The filter size and the number of filter elements are considered according to the flux provided by the production process. Generally speaking, the flow rate of a 10-inch filter element is 0.5 ton/hour (the flux of filtered water). If the flux is to reach 1.0T, a 30-inch filter core can be selected, and some leeway can be reserved. The accumulation of impurities on the surface of the filter membrane will lead to a decrease in flux. If a filter with a core of 20 inches is used, it may not meet the requirements.
3. Pressure and temperature
The appropriate filter element is determined according to the filtration temperature, pressure, and disinfection conditions during filtration. The maximum working temperature of the general filter element is 80~90°C. Activated carbon fiber is 65°C, stainless steel folding is 200°C, and titanium sintered filter element can reach 280°C.
The maximum pressure of the microporous membrane folded filter element is 0.42Mpa/forward, the titanium sintered filter core is 0.5Mpa, and the stainless steel folded filter core is 0.6Mpa.
4. Excessive requirements
The degree of precision that filtration needs to achieve (requirements for sterilization and particle removal). The filtration efficiency of deep membrane filtration and absolute membrane filtration is different. For example, the absolute accuracy of 0.2um is basically used for sterilization; the relative accuracy of 10-20um can be selected for the removal of visible particles.
5, Filtering by step
According to the pollution degree of the filtrate and the impurity content, the pre-filter should be selected and the number of stages of filtration should be confirmed. The purpose of pre-filtering is to prolong the life of the final filter and reduce the cost. The design of the pre-filter affects the effect and life of the final filter.
