What should I look for in an air assist pump?

I have a number of different pumps and tank, from a large shop compressor to a desk top air brush, but I’m not certain if any of them are suitable for use as air assist pumps on a hobbyist laser cutter.

What should I be looking for in terms of specification, and is there anything that I should avoid?

I’d rather something that I already have rather than buying something new.

This post shows the pump I use.
You can use its specs as a reference.

At my hackspace, we just added a second regulator to our main compressor. We keep that at around 200 kPa, and we have an additional regulator on the laser cutter itself if someone wants reduced pressure.

It’s helpful to advise us of the type/size of laser…

I used the one that came with my China Blue 50W, but it was pretty sorry.

I when I went with a large air compressor and use about 60lbs when I cut. Much easier and cleaner with the higher pressure, volume.

If you have a large compressor, use it… the main use is to keep debris off the lens.
