Digital Filter Monitor (Duster 2000)
Shows you when to clean the filters
– 6 –
CFM
The digital read-out on the front of the machine indicates the airflow
volume in cubic feet per minute (CFM).
As the filters get loaded with dust the reading goes down if you
operate the machine at the same speed. Check filters on
high position.
After several months, the reading may be down by 500, even
after vacuum cleaning. Then it will be necessary to high pressure
wash only the pleated filters, but not the green pads.
On the Duster 600 the Smiley Face Flip-up stays down horizontal
when the filters are plugged.
