3.6 Radial fan
3.6.1 Position and function
The optional radial fan is used to support cooling and the optimum
distribution of the steam-air mixture in the sterilisation chamber.
The motor is located on the outside of the door or the rear of the
sterilisation chamber.
It drives the fan wheel on the inside through a magnetic coupling. To
ensure that it runs smoothly, the motor must be carefully centred.
The fan wheel is press-fitted on the shaft. When required, only the
complete fan wheel with bearing can be replaced.
