specifications. 

10.1 Defining the Fan Air Capacity 

Fan air capacity defines how much air is provided when the fans run at full speed. These numbers are 
used to calculate minimum air requirements.   

 

In Measurement System, page 40, define the measurement unit.

Understanding Levels of Ventilation 

When minimum ventilation is operating, the ventilation works to ensure that there is sufficient clean air 
while keeping the air temperature close to the target temperature. If the temperature is above the target 
temperature by a sufficient amount, the ventilation level increases (after a delay time).  If the increase in
