Cleaning the filter
Dismantling the filter element:
Fig. 27 Sample gas filter: Dismantling the filter element
1 Remove sealing rings [A] from the face side of the filter element.
2 Remove the screw connection [B] (on the analyzer unit types “inline” “industrial
housing”: including the sampling pipe).
3 Remove pressure plate [C].
4 Remove filter element [D].
If the displayed calibration deviations are now unusually high, the sample gas
filter is probably leaking.
●
The filter element is a cylindrical sleeve of sintered metal. Dirt deposits
form on the

The following applies for the analyzer unit types “inline” and “industrial
housing”: The sampling pipe of the sampling probe is secured directly on
the filter element.
