Air assist is very helpful. It does a number of things that help the cuts.
1. Reduces the "smoke burn" on the material
2. It removes the soot in the groove that prevents a nice even burn, or in my case, a burn at all

I have an air assist set up on my machine that is connected to a shop air compressor. I usually keep my PSI at around 20. You can go as high as you want as long as it does not shift the material you are working on.

I know some use small compressors like the ones used for air brushes as they are smaller and quieter. I have even seen some just use a computer fan.

All in all, if you plan to cut, I think you will notice a HUGE improvement with an air assist.

thanks loki bout what size you think your nozzle is trying to figure out a good rainge for nozzle air speed  so every thing you gave is a tremondus help   
                                   Thanks Krazy D.

Here are some pictures of my rig
http://benboxlaser.us/index.php/topic,927.msg22759.html#msg22759

Here is the nozzle I used

Here is the hose I used

In the pictures, I used a piece of coat hanger and bent it to how I wanted my blower to be. I used it as a "spine" to attach the blower nozzle to.

I'm using the computer fan setup designed by pawpawpaw85 .
I find my cuts are cleaner and more consistent.  I'd be interested in hearing how a higher-pressure setup compares in terms of cutting efficiency.

If you are making deep cuts or cuts in resistant material, that blower will not accomplish what is needed. A fairly 'stiff' and small stream of air is required. I find that 60 PSI air delivered via a blowgun will clear the kerf but I have to hold the material in place so it will not shift. A small nozzle, close to the focus point is what is needed.
