<p class="MsoNormal">HI,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a rule of thumb that is used to set a maximum capacity (# of people) in a cleanroom. I have class 10 rooms that are only 360 sqft with 450 air changes per hour and if I have >3 people in the space I have issues with particle control.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any ideas on maximum capacity in a room by class?<o:p></o:p></p>
