HEPA Rated Filter Bag
This vacuum bag is used on Random Orbital Sanders with Self-Generated Vacuum to collect sanding dust.
Self-genertated vacuum sanders eliminate the need for vacuum hoses and vacuum cleaners, or connections to a central system.
This makes it much easier for the operator to move around the work piece, or to move to a different location.
These filter bags attach to the tool using the 3M Filter Bag Adapter supplied with each tool.
The bags are HEPA rated, and provide an exceptional 0.3 micron filtration level.
Depending on your application, the useful life of these bags can vary dramatically.
When used on boat interior wooden joinery and cabinetry, or in a woodshop, they can last until they fill up - typically a "whole day" of use.
In a boatyard, however, the particularly sticky pigmented dust generated from sanding bottom paints and topside coatings, tend to clog these filter bags long before they fill with dust.
When sanding thick layers of antifouling paint, these bags may clog after 20 minutes of use.
Having said that, self-generating vacuum sanders can be ideal for sanding small, "spot" jobs, or on ther interior of a boat, for their physical convenience compared to central vac systems.
