| Through several decades of experience
in production of fans and other process equipment for the
industry, we are aware of our responsibility with regard to
safe operation for the equipment. The best material selection
together with good craftsmanship is of great importance, whether
the fan shall be installed in conjunction with a paper machine,
for ventilation of large production areas or utilized in the
offshore industry under servere conditions.
Dependent on the design, the motor can be flanged
directly to the central tube and the fan impeller mounted
directly on to the motor shaft. Using belt drive where the
bearings and the shaft are mounted into the central tube,
the central tube will be fixed in the center of the fan housing
through heavy gauge guide vanes.
For obtaining a max. stability, heavy gauge
materials are utilized.
Fan requiring motor powers of 75 kW or above,
has as a standard 5 mm sheet metal thickness. Flanges on fan
sizes up to 1200 are at least 8 mm. For fan sizes 1250 up
to 2000, a flange thickness of 12 mm will be used. The flanges
are fully welded to the fan housing.
The fan impeller wings and hub are made in cast
silumin G-A1 Si 10 Mg. Profile thickness in the impeller wing
is for example for a fan having a hub diameter of 630 mm up
to 37 mm. This indicates the great stability of the fan impeller.
An impeller for fan 1250.500.8 has a weight 59 kgs.
