FBA In-line centrifugal fans combine the performance characteristics of the traditional scroll-type centrifugal fans with the space saving advantages of axial type fans. These fans are applicable for general building ventilation, commercial and industrial air conditioning. They are also suitable for industrial process supply and exhaust, drying and cooling and combustion air supply.
The key features of FBA In-line centrifugal fans are:
Backward inclined centrifugal impeller
For superior performance.
High efficiency / low operating cost
The design of the spun inlet and aerodynamic
conversion vanes provides a smooth, turbulent – free
airflow through the tubular housing, resulting in a
high, broad efficiency curve. This delivers lower power
consumption, resulting in reduced operating cost for
the life of the installation.
Quietness of Operation
The impeller design allows for air expansion over
the entire blade width, passing through the
backward inclined blading with relatively low
velocity and minimum turbulence.
True non-overloading absorbed power
The power curve peaks within the normal operating
range and at maximum efficiency. This built in
protection ensures that the motor selected will not
be overloaded.
Stable pressure curve
The inherent design of the backward inclined impeller
results in a steep-rising pressure characteristic over
a wide range of capacities. This ensures minimum
changes in volume with shifts in system pressure,
providing extremely smooth operation.
Equal inlet and outlet diameter
This means that one size of duct may be used for
both the inlet and outlet. No transformations are
necessary, making installation simpler and less costly.
In-line centrifugal fans are available with impeller
diameters ranging from 470mm to 1530mm.
