About the Air Assist:
Based on my original design for the D1, this design continues the trend of not require cutting the laser shield (and potentially voiding your warranty) or removing the shield entirely. It was designed after reading through studies done for industrial lasers, which concluded that offset jet assist designs were up to 20% more efficient than standard cone types.
The resin printed assist is positioned back from the focal point of the laser beam with its brass nozzle up front, centered on the focal point. In the event of material ignition, the air jet from the nozzle pushes the flame away from the laser module and the body of the assist itself so that both have some protection. Because of its positioning, it is also not as susceptible to damage from flash ignition as cone designs.
Air supply:
This air assist is fitted with a brass nozzle jet, one size for compressors and one size for aquarium pump. Compressors, such as little airbrush compressors like I use, work great as is. They handle 30psi and better, and, the pressure regulation is good for producing different effects when carving or just to push the smoke away from the laser’s lens. The popular aquarium pumps benefit from a different nozzle, being unable to manage a single pound of pressure, making it up air volume.
Tubing:
The hose nipple on the assist is set up for 1/4″ OD tubing, the same kind typically used for drip irrigation. The kit includes a quick connect fitting, which the buyer can decided to use or just go with the built in hanger on the modules. 5 feet of tubing come along with it, just in case you need it.
Quality:
Each assist is tested for fit, leaks, and performance before being packed for your order. Any lot built with more than 25% failures is thrown away entirely, to minimize latent defects from going to customers. As time goes on, I make adjustments and changes based on owner feedback and failure data, part of the continual improvement philosophy.
Installation:
The process has been made as simple as possible, requiring no tools at all. It just slips on and stays there. Be sure to push it all the way down so it’s flush with the base of the lens ring.

This is a great air assist nozzle. Ìts very well made and does much better with greater results than the stock one that comes with the 20watt. I definitely recommend purchasing this product!😁

Dimensions are flawed and do not fix the D1 Pro 20w. The tubing becomes kinked and restricts air flow. I am unable to use and have now reverted to the xTool cone style air assist. Out 30bux 🙁

Customer made zero effort to contact Geeks At Large about any issues they had, but instead waited until they had another product on the way to post this review. Had they gotten in touch in the first place this matter would have been resolved for them.
