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
25 Pa
Air gap (a) 10 mm
K-factor 4,05
Entered in the equation:
q = 4,05 · √ 25 = 20 l/s
Adjustment
Turn the front plate until the air gap (a)
reaches 10mm. If the pressure meter shows
24,4 Pa the airflow is 20 l/s.
The adjustment pressure can be measured
by inserting the probe in the centre hole
situated behind the plastic cover plug in the
middle of the front plate.
