Air Assist Hose

Quick question: what kind of hose should I use for air assist? Pvc pipe seems way too rigid. Should it be silicone or another very soft hose?

Normally you use a soft aquarium airline hose which is very flexible. Something like this:

How are you setting up the assist? Are doing to use a different laser head or are you going to using a piece of metal tubing?


I bought this drag chain and both of the nozzles.

From Etsy huh? Interesting. You will need to determine the size of the inlet holes on the mounts, but I imagine 3/16" (4.5mm) tubing will probably work. Looks like a squeeze fit.

I had no idea where to buy it when I bought it. So, it is what it is.


You know, it actually turned out great! Super easy to install. I managed to completely mess up my alignment so I had to fix that. Air assist is working very well. The pump is rated at 70L/min.
