The reason why the air filter should be matched with the purchase: The misunderstanding of the average person is that it is considered that the single filter corresponding to the processing precision can be selected according to the required air quality, and the cost can be saved. In fact, the air quality required by the filter is determined by the processing accuracy of the selected single filter, but there is no pre-treatment protection of the pre-lower primary filter. The high-precision filter will soon be overloaded. The blockage speeds up the frequency of replacement of the filter element, which increases the production cost in disguise. Air filters can reduce the air dew point: air filters generally remove only solid, liquid particles (drops), while water vapor and oil vapor can pass through the filter material without any obstruction. Therefore, mechanical filters cannot filter them out (except for activated carbon filters). To fundamentally remove water vapor and oil vapor, only use a dryer to reduce the dew point temperature of the air. The efficiency of the air filter is closely related to the air temperature: the temperature of the oil and water contained in the compressed air affects the efficiency of the filter. For example, when the temperature is 30 ° C, the oil content flowing through the filter is 5 times that at 20 ° C; when the temperature rises to 40 ° C, the oil content flowing through the filter is 10 times that at 20 ° C. Therefore, the filter is usually installed at the lowest point of the compressed air system. Belt dryer The difference between the domestic filter element and the imported filter element: mainly due to raw materials, equipment and other reasons, the domestic filter element has been lagging behind the imported filter element in the filter material and processing technology. The detection means and the backwardness of the testing equipment have made the domestic filter element unable to improve the quality due to the lack of quantitative authoritative analysis. Compared with imported filter cartridges, domestic filter cartridges are generally rough and bulky. Air filter accessories: Individual selection of air filter options: internal active drain, external active drain, differential pressure gauge, differential pressure gauge, electronic differential pressure indicator and level indicator. In the air filter option, the internal active drain and the external active drain are used to actively discharge the mixture of oil, water and dust filtered out from the filter element to the filter, reducing the recovery efficiency and the fragmentation efficiency. The level indicator is used to indicate the amount of mixed contaminants in the filter, such as oil, water, dust, etc. (the internal active drain can be monitored and the manual manual discharge can be monitored). The vacuum filter differential pressure gauge, differential pressure gauge, and electronic differential pressure indicator are used to guide the change of the filter cartridge. The replacement period of the air filter element, the replacement period of the vacuum filter element is determined by its pressure drop. Generally, the pressure drop exceeds 0.68kgf/cm2, the filter differential pressure gauge pointer points to the red area, or the work is over 6000. It will be replaced in 8000 hours (one year). The activated carbon filter is replaced when the smell is detected downstream. The filter element of the filter should be replaced regularly: as the filter element continues to be contaminated, the flow of gas will become smaller in the system and the pressure drop will become higher. At the same time, the energy consumption will increase. As a result, the cost of operation and production will increase. And increase the burden on the environment.

It is typically installed on the ceiling and can be in the form of a chandelier, Semi-flush Mount, Wall Sconce, or ceiling fan light. The design of Foyer Light is often elaborate, and can be made of materials such as crystal, glass, metal, and can feature intricate patterns and decorations. It not only provides ample lighting, but also adds a touch of elegance and sophistication to the entrance hall.

Air filter installation process: The working pressure should not exceed the maximum pressure indicated by the filter; the filter should be installed after the aftercooler and the gas storage tank as close as possible to the point of use and the lowest temperature; the filter should not be installed in the quick opening. After the valve, and to prevent backflow and impact; the filter should be installed vertically and leave enough space underneath to replace the filter; the larger filter should be properly supported in the pipeline.
