Notes:
• Always use fleece filter bags when using
HEPA filters with dust extractor.

automatic or semi-automatic filter cleaning
will help extend filter life and maintain dust
extractor suction efficiency.
• With regular usage of the filter cleaning
system, the maximum vacuuming
performance is maintained longer.
• The filter cleaning system must be
activated when the suction power
decreases to the point of being
insufficient.
• The sound of the filter cleaning system

Automatic filter cleaning (AFC) (Available

the red membrane button a second time and
the greed LED light will turn on signaling the
AFC feature is activated (Fig. 3).
Air reversals will clean the filters every 15
seconds, maintaining the highest level of
suction power. Dust extractor suction will be
maintained as the filters are being cleaned.
Semi-automatic filter cleaning (SFC)
(Available on models VAC090S, VAC140S)
Air reversals will clean the filters when either
the actuator on the hose is depressed, or the
airflow is blocked by covering the end of the
hose. No suction will be available as the
filters are being cleaned (Fig. 13).
