• The cover can be mounted either upward or downward. Use
Flow Rate and Static Pressure
The characteristic graphs provided for each of the models represent
the average of actual measurement data obtained under the
measurement conditions given below. They are provided as
reference for determining the Fan most suitable for the type of
cooling required; the actual characteristics may differ from the values
represented in the graphs. The graphs are not intended to guarantee
these characteristic values.
A simple explanation of the flow rate/static pressure characteristics
and the methods of measuring them is given below.
Note: The following symbols are used in the graph below for the flow
(flow rate = 0):
Fully close the damper. Take the pressure difference between
chamber B and ambient pressure (Ps). The maximum value of the
pressure difference (Ps) is the maximum static pressure (Ps max).
Adjust the auxiliary blower to change the static pressure (Ps).
Measure the pressure difference between chamber A and chamber
B (Pd). Calculate the flow rate (Q).
(static pressure = 0):
Fully open the damper and adjust the auxiliary blower to set the
static pressure to zero (0). Measure the pressure difference between
chamber A and chamber B (Pd). Take the flow rate (Q) calculated at
this point as the maximum flow rate (Q max.).

Measure pressure difference across nozzle (difference between chamber A
and B pressures) and calculate air flow rate.
Measurement was performed using the multi-nozzle
double chamber method based on AMCA (Air Moving

Fan Operating Point:
A Fan installed in equipment operates near the point where the Fan
characteristic curve crosses the system impedance curve.
