I found a little side channel blower in fleaBay for about £60 - with a little nozzle it blew chips everywhere, so much so that I had to throttle it back a bit. If you're tempted to go the same route just be aware that those things come in different flavours of pressure and volume delivery, the one I found did quite a reasonable pressure, ~280mBar IIRC.
I find the noise of the air jet far louder than that of the blower itself.
