This is a laser head with air-assist . The laser head is capable of hosting a 15mm/18mm diameter focus lens and a 20mm diameter reflection mirror. With the O-ring in the lens holder, the laser head now can install a 15mm diameter focus lens.


This is a GREAT replacement for K40 or D40 that comes with no air-assist in original packing!


Air plug outer diameter: 5.5mm


Mounting plate cut hole requirement : 14.5mm in diameter


Suggested tubing:  5X8 Silicon Flex Tube for CO2 Water Cooling

Don't buy!
Terribly made. The screw that's suppose to fasten the nozzle to the lens holder can't be screwed in because the hole is too shallow.

18 mm laser head with air assist
I primarily use my k40 for engraving acrylic for edge lit lamps. I can't even tell you how much improvement this upgrade has made. It's incredible. I'm able to turn down my engraving power by 20 to 25% to get the same results. I also recommend the 18mm lens and a 950gph air pump for the air assist. You won't be disappointed.
