Inflow Velocity Test Procedure
Inflow velocity can be determined by use of a thermal
anemometer at the face of the work access opening by
taking the following steps:
1. If the meter has an adjustable time constant, set
it at 10 to 15 seconds.
2. Take three rows of readings at 8, 12 and 16
inches from the top of the opening at positions
that are 6 and then 12 inches in from both
sidewalls. This will yield a grid of 12 sampling
points. See Figure 6-8 for probe placement.
3. Add the 12 readings together and divide by
twelve to obtain the average inflow velocity.
4. The factory inflow velocity setting should equal
or exceed 65 FPM. The blower speed can be
adjusted by turning the speed control located
behind the front dress panel.
