1. Speaking of high-efficiency air filters, in a clean clean room, whether it is a large-volume high-efficiency air filter installed at the end of a purification air conditioning unit or a high-efficiency air filter installed at a high-efficiency air outlet, these must be accurate The running time record and cleanliness and air volume of the air filter are used as the basis for replacement.For example, under normal use, the service life of the high efficiency filter can be as long as one year, and the service life of the high efficiency filter can be as long as two. There is no problem at all for more than a year, of course, this also depends on the quality of the high efficiency air filter, and it may be longer;
2. The high-efficiency air filter installed in the purification equipment, such as the high-efficiency filter in the automatic air shower room, if the front-end primary filter is protected, the service life of the high-efficiency filter can be as long as two years.
The high-efficiency filter on the purification workbench can be replaced by the prompt of the differential pressure gauge on the purification workbench. The high-efficiency filter on the clean shed can be determined by the detection wind speed of the high-efficiency air filter. time. Should it be replaced regularly?
3. Some experienced air filter installers have summed up their valuable experience, and I will introduce them here, hoping to help you grasp the time of air filter bag replacement more accurately, and display it as a differential pressure gauge in an air conditioning unit. When the air filter resistance reaches 2 to 3 times the initial resistance, the maintenance should be suspended or the air filter should be replaced.
