The replacement standard of precision filter element filter is mainly based on the following considerations : ‌

‌1. Use time : under normal circumstances, the replacement cycle of precision filter element is 3-4 months. The specific time can be adjusted according to the actual use, for example, home users may be replaced once a month, commercial users every two months, industrial users every three months.

‌2. Pressure drop : When the pressure drop of the precision filter exceeds a certain value, usually 0.68kgf/cm² or when the differential pressure gauge pointer points to the red area, the filter element needs to be replaced. In addition, after 6000-8000 hours of work (about a year) should also be considered for replacement.

‌3. Filter effect : If it is found that the filter effect is reduced or the pressure drop exceeds the standard, it should be replaced in time. Regularly monitor the status of the filter element, and make a personalized replacement plan according to the actual situation.

‌4. Water quality and use environment : poor water quality or harsh use environment will accelerate the pollution and blockage of the filter element, so it is necessary to adjust the replacement frequency according to the water quality and use environment.

‌ Replacement steps :

‌1. Isolation filter : close the intake valve or compressed air supply system and completely relieve the pressure before closing the outlet valve (or completely relieve the pressure through the filter drain hole).

‌2. Remove the old filter element : unscrew the shell, remove the old filter element, and clean the filter shell.

3‌. Install the new filter : Install the new filter in place, ensure that the sealing ring is intact and firmly installed.

‌4. Check the tightness : close the filter outlet and slightly open the inlet valve to check for leakage.

‌ Maintenance suggestions :

‌1. Regular check : regularly check the status of the filter element to ensure its filtration effect and tightness.

‌2. Clean the filter housing : every time you replace the filter element, clean the filter housing to ensure that the inside is clean and free of impurities.

‌3. Personalized plan : According to the actual use and water quality and other factors, make a personalized replacement plan to ensure that the filter element is always in the best working condition.
