Looks exactly like the Clarke one I've got (except for the fact that mine has legs rather than being a bench top)
They are slow to use, I've got 14 cfm compressor with a 150 Ltr tank and it can't keep up with even the smallest nozzle.
If you have a mega compressor you won't be able to see what you are doing after 5 minutes anyway unless you fit some form of extraction (anl old Dyson does the trick.)
Oh, and you have to breath out whilst turning your head or the perspex window fogs up.
Having said all that they are superb for cleaning rust, cr@p and paint off, beats a wire brush any day!
HTH
