FILTERS AND FILTER
OPERATION
The Dustblocker 900 separates the dust in two phases:
During the first phase, the G4 pre-filter is used. The filter collects the larger dust
particles and protects the H14 hepafilter. See the replacement table containing the
recommended periods for changing the G4 pre-filter.
During the second phase, the H14
hepafilter is used. This filter will collect
the dust that is dangerous for people's
health and that is not visible to the
naked eye. See the replacement table
containing the recommended periods for
changing the H14 hepafilter.
For replacing the G4 pre-filter as well
as the H14 main filter you must take the
airflow into account. The air is sucked
in at the side of the filters and blown out
at the opposite sideAt the front of your
Dustblocker 900 you will see a G4 pre-
filter. In case of daily use, we recommend
changing it 2x per year. Of course, this
depends on the contamination of the
air in the environment. If you regularly
replace your pre-filter, you will relieve the
strain on the hepafilter.
To replace the filters, pull the spring clips
out and remove the front cover. Replace
the filters in the same order and as per
direction or row on the filter
