Xiaoyi will introduce to you the time and service life of the air shower room cleaning machine.
Generally speaking, the special primary filter for the air shower room needs to be cleaned once in about 3-6 months, and the cleaning times are less than 3 times. The high efficiency filter should be replaced in about 2 years. Of course, this is only the suggestion of the air shower room manufacturer to most users. The actual analysis is as follows:
It is a good method to determine the life of the filter by measuring the final resistance of the filter in the air shower chamber with a differential pressure measuring device. As long as the filter reaches the final design resistance, it needs to be cleaned or replaced.
Empirical methods can also be used to determine the service life of filters, such as high efficiency filters in normal use, two to three years to replace once, but this data is very different. Empirical data can only be found in a specific project through the operation verification of the air shower chamber, which can only be used by the air shower chamber. If the application scope is extended, the life deviation is inevitable.
The high efficiency filters used in the air shower rooms such as the large infusion workshop, the solid preparation workshop and the aseptic laboratory have been tested and replaced, and their service life is more than three years.
