Configure Alarm
To successfully calibrate the airflow monitor, it will be necessary to change the
face velocity by adjusting the airflow exhaust volume. The exhaust volume can be
adjusted using the speed control located behind the front panel on the XPert
Filtered System or on the back of the FilterMate. For the XPert Filtered Station,
the exhaust volume is adjusted through a damper in the building exhaust system.
The following inflow face velocity speeds are recommended to successfully
calibrate. To begin, determine what the low airflow, low warning airflow, normal
airflow, and high airflow shall be.
