In the article How Classification Impacts the Design of a Cleanroom which was written for R&D Magazine, we explained how to determine the required CFM, the quantity of HEPA filters, and the quantity of low air returns in a cleanroom. To simplify this even more, we created a tool that estimates it for you. You don’t need to crunch the numbers yourself anymore. You can simply use our brand new cleanroom calculator tool! Simply input the answers for each classified room you have.
What can you determine with our cleanroom calculator tool?
Total airflow in cubic feet per minute (CFM) needed for the cleanroom project
Air changes per hour (ACH) per classified room (ISO 8, ISO 7, ISO 6, ISO 5)
Quantity of low air returns
Quantity of HEPA filters
Quantity of lighting fixtures
How can you use the cleanroom calculator tool?
For every classified room (ISO 8, ISO 7, ISO 6, ISO 5) in your cleanroom project (anteroom/gowning room, clean zone, etc.), complete a separate row in the table with:
Room length (ft)
Room width (ft)
Room height (ft)
Cleanroom class (ISO 8, ISO 7, ISO 6, ISO 5)
Process generating particles
See how it works
Clients often come to us specifically requesting an “ISO 7 cleanroom” or an “ISO 8 cleanroom.” What they often fail to realize is that the ISO class does not define the layout of the cleanroom; it only defines the cleanliness level that needs to be met. See below how size and classification can influence the cleanroom design.
Same ISO Class Cleanroom, but different size
Small 14’ x 10’ ISO 7 cleanroom with a 6’ x 10’ ISO 8 anteroom
Large 80’ x 100’ ISO 7 cleanroom with a 10’ x 20’ ISO 8 anteroom
1) Small 14’ x 10’ ISO 7 cleanroom with a 6’ x 10’ ISO 8 anteroom
2) Large 80’ x 100’ ISO 7 cleanroom with a 10’ x 20’ ISO 8 anteroom
Here is an example for a 55′ x 35′ cleanroom with the Cleanroom Design Calculator
