In line Centrifugal Fans

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.
