<p class="MsoNormal">I am curious what others have as a setpoint for their cleanroom pressure relative to an unclean or lower classification cleanroom. I have found some information which suggests 10-15Pa is more than sufficient. We have ours set quite high
at 60Pa but it typically sits at 45Pa. If you have tried adjusting the pressure, have you noticed any change in cleanliness/particle counts? Any information would be really appreciated.<o:p></o:p></p>
