We have used Kinetronics products in our photo lab for more years than I care to admit Their brushes, Ionizing Air Guns are tops!
In the fitting area of our frame shop we use their static brushes - but, to be honest, we just use a regular air hose - but very rarely - I prefer the brush as it "picks-up" the dust rather than blowing it around onto something else.
If you're having a problem w/ dust - I would look into an ionizing air cleaner. One or two of these units (we got ours from Sears) will help remedy a dust problem
(So does keeping the work area clean )
