Why do we need to replace the filter element regularly?

Regular maintenance to achieve stable compressed air quality and high energy efficiency.
For a long time, people have been accustomed to judging whether or not they need to replace the filter element according to the pressure drop before and after the filter, because this is a direct reflection of operating cost. However, we must bear in mind that the primary reason for installing filters is to remove pollutants from compressed air. The frequency of filter cartridge replacement should comply with manufacturer's tips to ensure high quality compressed air.

"Why do we need to replace the filter element?"
In order to meet the stringent requirements of modern industry and the international standard of ISO8573.1:2001 compressed air quality grade, high quality filter media are applied to compressed air filters. However, the life and pollution capacity of such filter media are limited. We must remember that when the life of a filter expires, the quality of compressed air will no longer be guaranteed. The installation of filters is to obtain the compressed air that meets the specified quality requirements. Therefore, providing stable and qualified compressed air is the main reason for changing the filter element. The replacement of the filter element should be based on the manufacturer's prompting to obtain the required compressed air.

"The filter is equipped with a differential pressure gauge, and the pointer of the pressure gauge is located in the green area. Why do we need to replace the filter element?"
Many filter housings are equipped with a differential pressure gauge. Normally, these differential gauges are indicators but can not be used as precise pressure gauges, nor have they been calibrated. The representative area of the pressure gauge is composed of two colors, green and red. When the pointer is in the green area, the filter element need not be replaced. Differential pressure gauge is neither a service indicator nor an indicator of air quality. It only shows the pressure difference roughly and indicates whether the filter element is blocked in advance. Because the filter fiber in the filter core becomes brittle during the use process, even a small hole will cause the filter medium to break, and the pollutants will enter the downstream compressed air system without filtration. If this happens, due to the small pressure difference between the filter and the filter, the pointer on the differential gauge will always be in the green area, and the filter element will not be replaced in time until the user finds pollutants downstream. After this happens, even if the filter element is replaced, there will be pollutants in the downstream pipeline for a long time.

What is the consequence of not replacing the filter element?
In a short time, it seems to save the cost of replacing cartridges, but in the end it will lead to costly mistakes. We already understand the problems caused by compressed air pollution and the necessity of cleaning equipment. What kind of cost impact will the poor compressed air quality have on your business?
Destroy the adsorption bed of adsorption dryer, resulting in unplanned replacement of adsorbent.
Corrosion gas storage tanks and transportation network
Plug and freeze valves and air motors.
Damage machine
The pollutants emitted from valves and cylinders will form an unhealthy working environment. There are potential problems such as personnel injury, shortage of staff and financial compensation.
The efficiency of production process is low.
Destroy or damage products
Product rework
Increase manufacturing costs
Increase downtime

What are the advantages of changing the filter element on time?
Ensure high quality compressed air.
Adsorption bed for protecting adsorption dryer
Protect downstream equipment, operators and processes.
Reduce operating costs
Improving productivity and profitability
