How do I confirm the replacement interval of the HEPA filter?
How do I confirm the replacement interval of the HEPA filter?I. We start with high-efficiency air filters.We start with the high-efficiency air filter, in the clean clean room, whether installed in the purification of air conditioning units not the end of the high air volume high-efficiency air filter or high-efficiency air filter installed in the high-efficiency air supply, these must-have accurate running time records and cleanliness and air volume as a basis for replacement, such as in the normal use of the situation, high-efficiency filter life can be up to a year or more, such as front-end care If the front-end care is good, the service life of the high-efficiency filter can be more than two years without any problem, of course, this also depends on the quality of high-efficiency air filter, maybe longer; II. High-efficiency air filters installed in purification equipment, such as automatic air shower rooms in the high-efficiency filter, the front-end primary filter care to do a good high-efficiency filter life can be up to two years or more. The high-efficiency filter on the purification bench, we can replace the high-efficiency filter through the prompt of the pressure difference table on the purification bench, the high-efficiency filter in the clean room can be detected through the high-efficiency air filter to determine the time of air filter replacement, such as the high-efficiency air filter replacement on the FFU fan filtration unit is more through the prompt of the PLC manipulation system or the prompt of the pressure difference table to replace the high-efficiency air filter. III. Some of our experienced air filter installers have summed up valuable experience, here to introduce to you, expect to help you in grasping the air filter replacement time more accurately, in the air conditioning unit when the differential pressure table shows that the air filter resistance reached 2 to 3 times the initial resistance, should suspend maintenance or change the air filter. |
