6.8.1 Dust trap cleaning-Induction furnace
The dust from the furnace is trapped in the metal dust filter (2). The dust filter needs to be
cleaned after about 100 analyses.
Make sure that the filter is absolutely dry after ultrasonic cleaning. The porosity of the filter is 10
microns only and it is impossible to recognize whether the inside of the filter is dry, by simply
looking into it. Therefore it is advisable to have a second filter, in order to use it while drying the
other one. The filter can be dried with hot air. The replacement of the dust filter (2) takes only
about 5 seconds.
