LBA Bifurcated Axial
Bifurcation, meaning to split or branch off into two parts, is clearly demonstrated in the
bifurcated fan, which was developed primarily for high temperature and moisture laden air movement applications. The fan impeller is coupled directly to the motor, which is out of the air stream. The LUFT series LBA bifurcated axials are available in eight impeller diameters. The motors are available in standard three phase voltages and three speeds of 900rpm, 1400rpm or
Because of the various temperatures in which this type of fan can operate, they are supplied in three different categories. This must be considered when selecting and ordering the LBA bifurcated fan.
Medium temperature unit – suitable for temperatures up to 70°C, consisting of a bifurcated hot dip galvanized steel casing, aluminium impeller and a class ‘F’ insulated motor.
High temperature unit – suitable for temperatures up to 200°C. The construction of this fan is identical to the medium temperature unit with the exception that the motor chamber is fully insulated.
Extra high temperature unit – suitable for maximum temperatures of up to 300°C. This range is supplied with a steel impeller, a heavily insulated motor chamber and the motor shaft fitted with a aluminium cooling spinner.
