The rule of thumb is that you should not skip over more than one class when you move towards a cleaner room for example from iso 7 to iso 6 not from iso 8 to iso 6 as illustrated below.

Iso class 8 clean room air changes.

Iso 6 class 1 000 0 127 0 203 25 40 150 240. Iso 8 class 100 000 0 005 0 041 1 8 5 48. Cleanroom limits for airborne particulate contamination. Considerations for iso class 8 cleanrooms.

N is the iso class number which must be a multiple of 0 1 and be 9 or less d is the particle size in micrometers maximum concentration limits particles m3 of air class 0 1 µm 0 2 µm 0 3 µm 0 5 µm 1 µm 5 µm iso 1 iso 2 iso 3 iso 4 iso 5 iso 6 iso 7 iso 8 iso 9 10 100 1000 10000 100000 1000000 2 24 237 2370 23700 237000. The requirement of number of air changes per hour for any clean room depends on the class of the room number of personnel working in the area and frequency of access the room. For cleanrooms and clean zones shown in iso 14644 1 2015. Iso class 9 g.

Calculating cleanroom air change rates for iso 1 5 in cleanrooms with unidirectional airflow air exchange rate is calculated by air velocity sampling. Grade c is equivalent to class 10 000 or iso 7. Iso class 8 5 60 air changes per hour with a ceiling coverage of 5 15. Cleanroom industry requirements fall under iso 14644 5 2004 an iso category that lists the basic requirements for cleanroom operations.

Cleanliness of any clean room is maintained by the air changes per hour.

Grade d is equivalent to class 100 000 or iso 8. It s suggested that in cleanrooms with unidirectional airflow patterns iso class 1 5 air exchange rates can be calculated by average air velocity. Food industries ultimately depend on secure cleanroom environments for food safety. 5 48 typically measured micron sizes.

In reality however you can reach a cleaner class with fewer airlocks than described below with the appropriate air changes per hour. D recommended air changes per hour ach. Maximum allowable concentrations by cleanroom class.
