forward curved impeller. The range comprises
different versions and sizes of double and
single inlet fans. All these low pressure
centrifugal fans are designed for belt drive
operation.
All the fans are manufactured from galvanised
sheet steel and fitted with impeller manufactured from galvanized sheet steel.
Additional Information
Mounting feet as accessory allowing 4 different
positions (basic version).
The fan can be supplied with motor and belt
drive mounted.
On request

Fan selection
Selection of motor:
To determine the motor power required, the absorbed
power taken from the diagram should be multiplied
by a factor of 1,15.
Dynamic pressure:
The dynamic pressure shown in the diagram refers to
the total surface of the discharge outlet.
When the fan is used at free discharge, an additional
pressure drop equivalent to one time the dynamic
pressure should be added.
Sound level:
The values of the sound level shown in the diagram
are Sound Power in dB(A). To obtain the sound power
spectrum, subtract from these values the correction
values given in the chart below the diagram.
Example:
For the following working point:
- Air flow rate: Q = 10.000 m3/h (2,78 m3/s)
- Static pressure: Pst = 30 mmcda (294 Pa)
- Selected fan: CBP-18/18

CBP - 18/18
372
The other values read on the diagram are:
- Air velocity in the discharge:
v=10,4 m/s
- Dynamic pressure:
Pd = 6,7 mmcda
- Absorbed power:
P = 1,5 kW
- Number of revolutions:
RPM = 633
- Efficiency:
η = 71%
- Sound Power Level:
LwA = 83 dB(A)
