Just curious what makes you so sure you need an air assist. Will you be doing a lot of cutting. Since your laser is a 45 watt it is not all that powerful to creat a lot of excess heating. I only have a 25 watt and don't do much cutting, mostly just lasering pre made items. But I have a built in air assist and never use it. I tried it at first but it seems to scatter the smoke onto the item on some things more than it helps. I finally removed the metal nozzle by the laser head. I scratched several acrylics when I bumped up against it when removing them. There are a lot of people here that use the laser more for cutting and fabricating pieces so they might have better imput of whether you need it if that is what you will be doing. lj http://logojohn.webhop.net/

I do a lot of cutting and etching, from wood to acrylic. About the only time I don't use the air assist is when I am etching on Rowmark Material. The air assist deposits the etched debris back on the hot material where it sticks. However when cutting oak, cedar and acrylic I always use the air assist. In certain spots on the wood there might be more fresh "sap" which flames up. and on the acrylic, every once and a while it will craze the acrylic.
I am using an Epilog Legend 32EX 40 watt.
