Example
Formula given
q = k · √ Pi
Where q = airflow (l/s)
k = K-factor
P
i
= adjustment pressure drop (Pa)
Using the formula to calculate airflow
Size Balance-E 100
47 Pa
Air gap (a) 0 mm
K-factor 1,46
Entered in the equation:
q = 1,46 · √47 = 10 l/s
Adjustment
Adjust the centre cone until the air gap (a)
reaches 0mm. If the pressure meter shows
46,9 Pa the airflow is 10 l/s.
Note! Tighten the screw in the back of the
valve to fix the setting.
