DC23 has a 6-stage filtration process:
1.
Outer cyclone:
as the air enters the clear bin, large dirt and debris is separated from
the airflow.
2.
Shroud:
the air is then directed up through the shroud, which acts as a fluff and hair
separator.
3.
Core separator:
small/fine dust particles are then separated from the airflow in the
core separator.
4.
Inner cyclones:
smaller/microscopic dust particles are then separated from the airflow
in the inner cyclones. The air flows out of the cyclone assembly and into the duct, before
reaching the pre-motor filter.
5.
Pre-motor filter:
traps the last remaining particles of microscopic dust, allowing only
clean air to pass through.
6.
Post-motor filter:
lastly, as the clean air passes through the motor, it collects carbon
dust particles from the motor brushes. The post-motor filter traps these particles before
the air is then exhausted back into the atmosphere, thoroughly clean.
DC23 Filtration
The dirty air flows through the wand and hose and then continues up the inlet and into the clear bin.
The filtration process starts in the clear bin. Larger debris is separated from the airflow. The air is then directed through the shroud
and up through the core separator and on into the smaller cyclones in the cyclone top. The air then travels down the exhaust
duct before continuing through to the pre-motor filter and into the motor housing and up through the post-motor filter, where it is
exhausted into the atmosphere, thoroughly clean.
This section illustrates the direction of airflow through DC23.
DC23 Airflow
Lifetime pre-motor filter. The pre-
filter separates particles as small
as cigarette smoke (0.1 microns).
Should be washed every 3-6
months.
Lifetime HEPA post-motor filter.
Never needs washing or replacing.
