Lower leak Estimates using: Leak audit
Set the door fan to produce a 15 Pa positive pressure. Open the door panel up to witness
smoke moving at “full speed”. Locate enclosure leaks, measure the open area. Test the
leak with smoke in the area where the leak was measured. Mark down the % of full speed
that each leak appears to be. This will tell you whether something upstream from the
leak was slowing it down so in effect by knowing the area and speed you are determining
the approximate effective size of each leak.
Mark this data down for later entry into the Leak Audit button on the Lower Leak tab that
lights up when you enter “Estimated”.
