Changing intervals of the filter elements
After a certain amount of operating hours, the filter elements must be replaced. This depends on the
produced amount of dust or gas. Nevertheless, the filters must be replaced at the latest if the signal horn
(pos. 3) is triggered off.
Depending on the application, it can be required to replace the filters even earlier.
We recommend the following changing intervals:
Filter element
Gross filter
Prefilter
Activated carbon filter
Main filter
Recommended operating period
50 operating hours
100 operating hours
100 operating hours
200 operating hours
