CONTAMINATED BAGS
3.0
The word "contaminated" is being used to describe a dust bag that has become
coated with a material outside the normal material the collector is collecting.
3.1
The usual materials that contaminate a dust bag are water, oil, or grease.
3.1.1
A very small amount of either water, oil, or grease will contaminate all of the bags
in the dust collector. This results in a complete change of dust bags.
3.2
Cleaning Contaminated Dust Bags:
There is no satisfactory method of cleaning contaminated bags.
3.3
Recognizing Contaminated Bags:
3.3.1
Generally, the first sign is to observe that the amount of air passing through the dust
collector is less than it should be.
3.3.2
Remove panels to bag house and check dust bags. (See page 6 for dust bag
assembly.)
3.3.3 Rub a dust bag with your thumb and forefinger. If the residue left on your thumb or
forefinger will not brush off readily, the bags are either wet, oily, or some of each.
3.4
Cleaning Contaminated Filter Bags:
Brushing or vacuuming is the only method that may restore contaminated dust bags
to usable dust bags.
