Centrifugal fan
Operating point
The control system calculates the operating point and
sets the default setpoint value for the fan.
During commissioning ensure that the following values
are not exceeded:
Maximum fan speed
Minimum fan speed
Motor rating
Do not change the clearance between the rotor and the
bellmouth inlet.

M2 Pressure measurement point on the bellmouth inlet
M3 Pressure measurement point in front of the parti-
tioning panel
The fans may be factory fitted with pressure measuring
devices (optional). The following pressure values are
measured at the pressure measurement point
( Fig. 63 /M2) in the bellmouth inlet ( Fig. 63 /1), the
pressure measurement point ( Fig. 63 /M1) in the fan
chamber, and the pressure measurement point
( Fig. 63 /M3) in front of the partitioning panel.
Pressure
Determined from
Static fan pressure
increase
Differential pressure
between M1 and M3
Effective pressure (
D
p
w
)
of the fan
The differential pressure
between M2 and M3 is
used to calculate the
volume flow rate.
Calculation of the volume flow rate
The K value is given on the TROX fan rating plate on
the air handling unit.
This value may be different from the K value on the
rating plate from the fan manufacturer (which should not
be used for the calculation).
