There are lots of inline fan options out there, but I can attest that the AC infinity 6" is dollar for dollar the best there is. One piece of advice though, unless you have really well sealed piping/vent tubes, placing it close as you can to the outside vent will prevent leakage, as it creates a negative pressure on the line all the way from the fan to the laser. If you place the fan close to the laser, (i.e. pushing the air versus pulling it), you create a positive pressure on your tubing and every leak will be blowing smoke out. And I have also found that that flexible foil tubing is like swiss cheese. Just stick a flashlight it and turn the lights off. You will see hundreds of little pin holes:) I have found that the black PVC wrapped tubes are a LOT better.
Agreed, that's the identical setup to what I used on my 100W OMTech for a while, and the pvc wrapped is far better. Another good option is semi-rigid flexible aluminum ducting used in HVAC systems. The ridges are far less pronounced, leading to better airflow and less resistance, easier to clean, and even stronger than the PVC wrapped flex. That's what I eventually switched to myself.
I seriously appreciate you providing such through and informative tutorials. I'm going to be removing my air assist using this tutorial and set up my CA Air tools compressor. Up next is the light upgrade from your other video. Seriously thank you so much!
I have a blue/gray 60 watt and this video was almost exactly how mine was set up except where the wires traveled once at the electrical side. mine connected at the bottom.But this video helped me SO much. Never done anything like this before!!Thank you!
Great video. I have a similar laser, mine is 60w did you upgrade your air assist and if yes have you seen a significant improvement with charging of the lasered material?
I did upgrade my air assist! I used a california compressor, a 24v solenoid to control the on/off of air, and a regulator to control the output of air. Yes, I saw a huge improvement in regard to quality of cut. Virtually no charring
Is there a way to get the infinity fan to turn on automatically like the OEM one? Could you run the wires from the original laser hook up buss and splice it in to the infinity?
You’ll need to measure the voltage. I’m pretty sure it’s 110v so if your LEDs have a 110 plug then you may be able to splice them. But by themselves you won’t because the LEDs you need for the system are 24v
Very informative video. Question, I have the same machine, how do yo remove the air assist?, is it the same prosses you did with the fan?. I want to use a California compressor for my machine. Thanks.
If that's all that's on the circuit then "maybe". The laser and exhaust, yes absolutely. The chiller may introduce banding in engraving when the compressor kicks on. If you have an upgraded air assist with a compressor then that needs to be on a separate circuit. I have my air assist and compressor on a separate circuit. My laptop, inline fan, and laser is on another
I have a 6 inch to 4 inch reducer after the inline fan because I'm in a basement with a small 4 inch dryer vent going through a block window. Normally you'd want to keep at at 6 inches if possible
@@EdmondsWoodshop Thanks! I asked because I just got a 50W OMTech and my vent is only 4", so I have to "reduce" also. Hows the smoke extraction? Work ok with the factory fan removed?
@@coastie792 as long as your ducting is anything crazy long you should be fine. I don't get a lot of smoke unless I'm non stop cutting. I have a long run of ducting too so that doesn't help me. The shorter the better
@@EdmondsWoodshop Good info, thanks. Fortunately, I can exhaust straight up into my 4" old water heater flue that goes right through my roof. It's probably no more than 8 feet. IT seems to vent well if I leave the blowers on for about a minute after finishing my burn to give it time to clear the smoke. Thanks again.
If you grounded your laser would you think about doing a video on how to ground the laser, I personally would find it very useful I hope others would too.
@@EdmondsWoodshop thank you for getting back to me I really appreciate it. I'm in the UK, our plugs are grounded too but I think there are some cases such as extensions and garage workshops that are not, even though I think they should be. I think possibly I've watched to many people's videos who say grounding the is a necessary step.
@@nolatone I will second what Cam said, it is a great improvement. I have the same laser except I bought mine off eBay and it's blue and black. Advertised as a 60w but only has a 50w tube. I have also done the chiller and air compressor like Cam did. Now looking at upgrading to a 100w tube. Stay safe.
@@nolatone I would be interested in knowing what speed and settings both of you are using for cutting 3mm and 6mm plywood, in cutting 3mm baltic birch with 70% power and 20mm speed and everything drops out and 6mm baltic birch on 80% power and 6mm speed and most everything drops out. Mine didn't come with a 2 inch focal lens so I bought one and use it most of the time. And I also added a mili amp meter to try and get a little longer life out of my tube and at 80% power it is running at 20ma.
Dumb question maybe...why not just leave the old fan in there and let it run. I kind of like the idea of two fans in series...if one dies for some reason then there's redundancy.

This video was great! I found it from the FB group and it was exactly what I needed! Great video and very helpful

I followed this literally step by step and was able to remove my fan. Your videos are so helpful! Thank you!

Thanks very much for making these videos. It's priceless to see the process of these upgrades before I try them myself.

Thank you! this was so helpful!
Glad it helped you out. I have since upgraded to an S8 ac infinity fan and posted a new video on it as well. Be sure to check it out
Thanks for sharing. I'm removing the stock fan today.
Great video!
Thanks Mike.
Thank you for your awesome videos!!
Great video, thanks so much!
good stuff, thanks

I have the same thought. Any feedback?
@@ripkenfan7186 nothing yet.... but the infinity works fine by itself
You could try plugging the fan into the outlets on the back of the laser. This would turn on the fan as well
Could I connect those fan wires to an led light strip for the inside of the machine?
You’ll need to measure the voltage. I’m pretty sure it’s 110v so if your LEDs have a 110 plug then you may be able to splice them. But by themselves you won’t because the LEDs you need for the system are 24v
Very informative video. Question, I have the same machine, how do yo remove the air assist?, is it the same prosses you did with the fan?. I want to use a California compressor for my machine. Thanks.
Can you run everything off one 15 amp circuit? Laser, Chiller, Air Assist, and Exhaust?
If that's all that's on the circuit then "maybe". The laser and exhaust, yes absolutely. The chiller may introduce banding in engraving when the compressor kicks on. If you have an upgraded air assist with a compressor then that needs to be on a separate circuit. I have my air assist and compressor on a separate circuit.

Great video. Question: Does your 6" duct neck down after the Infinity? It looks like the ducting gets smaller. Thanks!

Where are you located? If you happen to be in the US, plugs and outlets are already grounded.

I have that exact same laser. How much better does the Infiniti AC fan pull smoke and fumes out than the stock one?
It's like night and day difference. The stock one is pretty bad. This does so much better
@@EdmondsWoodshop nice. Most reviews focus on how quiet it is, but for me strength is huge.

@@donaldwalls8568 Yep, I've since added a 6" AC Infinity and now the laser lives inside my house with nofumes. Very nice!

In-line fan = 402 cfm
Stock fan = 99 cfm
Since airflow doesn’t match, it will bottleneck at the stock fan.
Can’t you just terminate the wires instead of fishing it all out?
Yep. Cap them too
