Replacing the suction fan filter cartridge KZTN3
Larger particles are collected by the suction fan filter. In order to prevent clogging, the filter
cartridge must be replaced periodically. The interval depends on the dust load in the sample.
As a rule of thumb, a load of 15 mE/m means the filter has to be replaced after 12 months.
If the load is lower, the interval increases accordingly.

Cleaning the sample lines
Particles from the sample can accumulate on the inner walls of the sample lines, which can
distort the measuring results. Therefore, sample lines of more than 50 meters in length must
be cleaned periodically with compressed air.
