Other -fullsize 2hp-50liter air tank had moisture problems on focal lens-fixed by adding 1meter 25mm wide pvc pipe filled with silca gel beadsjust before air assist-adjustable pressure regulator at laser cutter-1-2 psi etching and for cutting 3mm mdf 10psi or more if wanting perfectly clean botton of cut mdf peace

Dual air pumps - unknown flow/pressure. Pathetically weak. Will be upgrading to a higher powered pump when I get around to it.

I’m Lucky enough to have a shop air system. Back in my 1st All-Tek days, we ran a lot of air equipment in our panel shop and did a bit of painting on panel boxes and machinery frames as well, so I invested in a good air compressor and distribution system. It’s still going after 35 years, 3 pumps and a couple pressure switch/starters (original motor though!) I’m amazed the tank hasn’t rusted through yet - it will now that I brought it up…
It’s unlimited air for this application, but I quickly found less is more for air pressure on assist heads. It’s filtered/regulated down to 5psi at the Laser and then the flow is reduced down by a flow control valve.
The 7 1/2hp 80 gallon compressor is in another building so I don’t hear it at all. I timed it once and it cycles about every 23 minutes when I’m Lasering (took some doing as I don’t do many engravings that big).

I’m looking into buying a few pumps to test.
I’m designing a complete system for people who want an easy to install kit. Suggestions on the best quality pumps or your experience is welcome. (also on junk so I don’t waste my time and money on them)

I’ve designed a nice plug and play air assist kit but still need a quality pump to include as an option.

So if you have a pump you love - (or hate) I’d appreciate your thoughts on it. Please tell me what head you’re using and how loud it is.

We could use a “review” section on pumps anyhow, I hear occasional comments on them, but there doesn’t seem to be a “go to” favorite as there is with many K40 accessories.


I’m using an older select comfort air mattress pump for my air assist. Before that it was a 1960’s Craftsman diaphragm air pump. New pump is less air but a heck of alot quieter!

Will be switching from an aquarium pump to the shop air compressor after running some piping

Try and run the first 5 meters on a slight angle slopping up and install a drain tap at bottom of rise,or just unplug hose every couple of days with pressure in line at the time and see how much water comes out of line…

I just use a simple Lakewood 8 inch fan. I tried using low psi from my 60 gal compressor but I needed a more broad coverage rather than a focused point if air.
Lol works perfectly for my needs.

Tried compressor (with 24L tank), but run out of air very quick, even with using only low (0.5-1 bar) pressure on the output.
I’ve bought an airpump (Hailea ACO-328), and it is perfect.
tip: use high diameter tubing till you can, and smaller only at the end, where needed, so it will have smaller resistance (and higher airflow/pressure at the end).

@Akos_Balog I can confirm that! Now has twice flow!

Hello could u help me with that silicon gel thing? I have a problem with moisture on lens also
