6.6.4.2.6 Face Velocity Verification 

The AVC5000 Controller continuously calculates the face velocity using the real-time fume hood 
exhaust airflow and the total open area.  The AFC5000 Display/Alarm Module provides 
personnel working near the fume hood with an indication of the average face velocity in 
addition to providing audio and visual alarms and the ability to activate the purge function in 
case of emergency.  Prior to putting fume hood into service, the average face velocity displayed 
by the AFC5000 should be verified by performing a field measurement taken in accordance with 
ASHRAE 110-1995 (or latest edition).  If desired, the displayed face velocity value can be 
correlated to the field measurement using the Face Velocity Calibration procedure described 
below.  

6.6.4.2.6.1 Face Velocity Adjustment 

The face velocity reading can be correlated to a field measurement by performing the following 
procedure. 

1.

 

Open the 

“Face Velocity Adjustment” window by either right clicking on the 

Face 

Velocity Gauge (A) or through the Utilities Menu located on the Task Bar (B).
