12V air pressure system to clear chips?

[A_Camera]

Does anyone happen to know of any pump that will be able to run a hose down the spindle which will clear chips away from when I'm slotting. I can't run any coolant on my machine with how it is currently so this is the next best. Ideally would like it to be 12v or even 24v.

Have you considered a small 12V compressor made for pumping tires? I think that for cleaning chips it should work well, even if it "pumps" air puffs. Anyway, those are cheap, small and run from 12V, so easy to try and no big loss if it won't work. I don't think you'll need very high pressure, so no need for a large compressor for this purpose.

If you are determined to go 12v then an air suspension compressor might work, you can probably get one from a car breakers yard. I don't know if they are suitable for continuous operation though or what current they take.

What intrigues me is where you are getting the 12v from.

It doesn't need to be 12V, I can run it from the 24V PSU just the same. Is that uncommon or something as you seem surprised.

These 12v air pumps can draw a lot of current and can be very noisy electrically (brushed motor !). I would be careful you don't burn out your PSU
