HEPA Filter Leak Test
Procedure
To ensure dirty room air does not affect the HEPA
Filter Leak Test and that the control panel and sash
gaskets are sealing, take the following steps:
1. Turn on the enclosure and set the average inflow
velocity as indicated in inflow velocity test
procedure. Remove the postfilter
2. Tape closed all openings full length across top,
front and sides of the front dress panel as shown
in Figure 6-7.
3. Turn the photometer on and calibrate it per the
manufacturer’s instructions. The upstream
concentration of DOP will be approximately
24 ug/l. Use these values to establish the
upstream value of 100%.
