15 Liters/mn give me 2m/s output air assit (at the lens, could be better if I shorten the 2.5 m pipe).

far enought to protect the lens from the fume, nearly as good to improve combustion than the compressor (7.8m/s seem way to much). Still able to cut 3mm plywood.

Overall very happy, because the compressor was far too noisy. this air pump is quiet, a bit more loud than the stock exhaust fan, but less than the steppers. vibrations are not excessive (come with rubber feets).

  • point : AC, Quiet, cheap, allow built in with short pipe.
  • point : maybe go for the 25 Liters, 15 Liters is a bit just.

Thanks +Peter van der Walt for the original link.

I can make a test for you, how much weight do you want me to lift.
(kind of test to mesure the force), I will try a SD card.

4

+Peter van der Walt not enought to lift a normal size SD. (maybe with a better rubber end), you should try more than 15L/mn (25L/mn?)

5

25L/min is enought for a 60W or 100W lasercut ?

@Loic_Verseau Should be depending on the output size. mine is quite small and concentrated, so I got good pressure.
25L/mn (15) is quite a lot of Oxygene for combustion of that size.

Thank you @StephaneBUISSON , I was looking for something like that.

Amazon is playing with my nerves and my packages are stuck at their facility so no liquid coolant and no air assist. I will definitely check this item as I was looking for a good and silent air assist.

I’ve got the 25liter, will install it 7-8 may and tell you about it. I’ve tried it, it’s noisy but bearable, airflow doesn’t seems to be so powerful but since I did not try it in the machine I can’t really tell.

all depend on the size of the air assist output (i think most of the poeple here are oversized so they need bigger compressor).

Output looks the same as yours, the description said there was two output, (can’t affirm it as I can’t access Aliexpress from work either) but there is only one. We’ll see once I try it.

non je voulais dire a la sortie sur la tete (l’adaptateur 3d printed for me), c’est gros comme 2 aiguilles et directif sur mon design.

Ah ok, je n’ai pas verifié, j’ai recu la tête mais pas encore installée, j’etait déja bien content de faire marcher la smoothieboard avec le laser :stuck_out_tongue:
