How often should the high  effect filter used in FFU be replaced?


At present, high-efficiency filter has been widely used in optical electronics, LCD liquid crystal manufacturing, biomedicine, precision – dense instrument, beverage food,PCB printing and other industries dust-free purification workshop air supply end. With the continuous research and development of manufacturers, continuous progress, I believe that there will be more air filters in our life.


So many companies have configured FFU filter unit,FFU as a new type of purification equipment, occupies an important position in the field of purification, especially suitable for assembly or ultra-clean production line. In the clean clean room, whether it is the high-efficiency air filter with large air volume installed at the end of the purification air conditioning unit or the high-efficiency air filter installed at the high-efficiency air supply port, these should have accurate running time records and cleanliness and air volume as the basis for replacement. Users should regularly replace and record the replacement time to ensure that the air delivered is clean. But do you know how often the high-effect filters in FFU kits are replaced?


The high-effect filter in FFU is usually replaced once every 6-12 months under normal environment. And then the replacement of the filter has the following requirements:


1, The filter in the unpacking, handling and installation of FFU need to check: the technical performance of the filter is in line with the standard, there is no product certificate, to ensure that the filter paper is intact, do not touch the filter paper by hand, if the filter paper is damaged, it can not continue to use.
2. Replace the filter to lift the box of FFU, and then take out the filter that needs to be replaced and replace it with a new filter. After replacement, ensure that its frame has been sealed.
3, In 1-2 months after the use of FFU cleanliness test, if the cleanliness test does not meet the requirements, need to check the reason, and replace the filter as soon as possible to reduce the loss.
