They are used in projects where a pressure greater than that produced by an Axial Fan is required. 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.
