FILTERS AND FILTER
OPERATION
The Dustblocker 500 separates the dust in three phases:
During the rst phase, the front lter is used. The lter collects the larger dust
particles and protects the Pre and H13/14 hepalter.
The second phase is a Pre Filter which collects the ner particles and protects the
H13/14 hepalter.
During the third phase, the H13/14 hepalter is used. This lter will collect the dust
that is dangerous for people’s health and that is not visible to the naked eye.
The front lter 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 Pre Filter and H13/14 lter.
At the front of your Dustblocker you will see a 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 Pre Filter
you will lengthen the life of the hepalter.
It is simple to change the lter by
removing the two lock pins at the sides
and pull the lter out. At the top of the
Pre Filter you will nd a label with the
item number (Compare this number
with the number on the old lter).
Make sure that you place the lter as
indicated on the label : Airow
