Just in the process of rigging up some dust extraction which is going well, but I also need air assist for aluminium chip removal. I have a very loud compressor I don't want to use, can anyone point me towards something quiet that has the required flow rate and pressure (apparently some people use pond air pumps??) for blasting chips out of deep pockets?

I've also seen these small plastic fans you can slide onto the cutter but I can't imagine they can blow chips out of deep narrow pockets.
