Khun Artid,
I understand the theory of pressure change affecting temperature & dew point. Since the clean room & pressurized air is dry enough
from Khun Teerayuth data, I don’t see why there should be so much water condensation taking place and the root cause.
What you describing is, this is a common problem that involved pressurized air & cylinder, so it’s a PRB major process issue and affecting all product ?
Pls confirm. Thanks
