FILTERS AND FILTER
OPERATION
The Dustblocker 650 separates the dust in three phases:
During the first phase, the G3 front filter is used. The filter collects the larger dust
particles and protects the G4 Pre and HEPA Filter.
The second phase is a G4 Pre Filter which collects the finer particles and protects
the HEPA Filter.
During the third phase, the HEPA Filter is used. This filter will collect the dust that is
dangerous for people's health and that is not visible to the naked eye.
The G3 front filter which sits behind the metal mesh needs to be replaced on a
regular basis according to the contamination of the air in the environment. This will
lengthen the life of the G4 Pre Filter and HEPA filter.
At the front of your Dustblocker you will see a G4 Pre Filter. If the machine is
used daily we recommend changing it twice a year. Of course this depends on the
contaimination of the air in the environment. If you regularly replace your G4 Pre
Filter you will lengthen the life of the hepafilter.
It is simple to change the filter by
removing the two lock pins at the sides
and pull the filter out. At the top of
the G4 Pre Filter you will find a label
with the item number (Compare this
number with the number on the old
filter). Make sure that you place the
filter as indicated on the label :

Compare the information such as Model, Size and Efficiency to see if it matches
the data on the new filter.
Make sure you insert the filter as indicated on the label; with the arrow pointing
towards the centre of the Dustblocker (away from you):
If the HEPA Filter is exposed to water, this may shorten or end
the filter's life span.
Pre-filters and HEPA Filters cannot be cleaned and must be
replaced if they are saturated.
The DB650 is provided with a filter indicator connected to a warning led that
measures the pressure drop in the filter. In case of a pressure drop that is too high,
the red led will light up and the hepafilter must be replaced. If the Dustblocker is
used while the warning led lights up, this could affect the operation of the device.
