Is this a kitchen? Grease will glue dust to the blade.
It's a balance of forces: centripetal-air flow-grease bonding-static charge attraction. I expect the dust layer will be thicker near the root of the blades.
If you could find a '+' speed that is faster than "high," chunks would again fly off. Steady state speed will determine the amount of dust adhesion.
