Is it worthwhile replacing the Air Pump which was shipped with your Co2 Laser Machine, with an Air Compressor? Will it improve the results from your laser machine? Aren’t Air compressors extremely noisy, I don’t want all that noise in my workshop? To address that last question 1st, no not all air compressors are noisy, the one I used in this video is a silenced air compressor which a noise level of 60dB compared to that of other compressors the same size with noise ratings of around 97dB
In this video I will show one way to install and configure your Shop Air Compressor with your laser machine, and I will show a few before and after examples of a few cut results.
I use the Ultimate Air Assist installation on my laser machines, and I highly recommend this upgrade if you do not already have a similar system installed.

I recommend a Silenced Air Compressor with a volume of 50L or more, the smaller units may be sufficient for low volume work.
There are some great compressors available, this one I purchased here in Australia from Sedy, However If you are outside Australia, other compressors that I have heard are very suitable are those from California Air Tools.

Next you will need a Flow regulator with a water trap. Water vapor is a by-product of compressing air, and the amount of vapor produced is dependent upon the environment, humidity and temperature your compressor is operating in.

I use a NITO to 1/4 fitting and then use the following to connect the 6mm OD tubing.

So now we have it all set up what air pressure is required? That all depends on what you are cutting, I have tested with various materials and the results for each vary. So for now I will show a few examples of 3mm (⅛ inch) plyboard.
It should be noted that I only used a 2” lens for this test, normally If you are cutting this thickness I’d recommend a 4” lens, I’ll discuss more about lens selection in a future video.

Until Next time, take care
