Welcome, and I suspect you mean
>> keep a machine from being dust free.
keep a machine dust free.
Unless you can enclose the machine in it's own small dust free room with fan forced circulation and filters, I do not like your chances waving plastic rods around.
The better idea would be to vacuum the dust at the source rather than letting it spread, airborne, to settle and go where it may. If there are slitting rollers then vacuum ducts over those will be a good start. You need to tell us where and why there is dust. Just saying it is from paper helps not at all.
