Description 

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!

Mounting plate cut hole requirement : 14.5mm in diameter

 

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

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.

A Must-have
It improved the engraving quality a lot, don't forget the replace the lens with 18mm though (I bought the lens here as well). I don't know if it's the lens, or the head or both together improved the quality but I am very satisfied.

Must have upgrade
I purchased this item after having done some minimal hacking in the infamous "K40 - laser from China". For me, this was a drop in replacement that required no modification to the machine. I would suggest a better drawing showing where the lens goes as I had a little trial and error here. There was a spacer ring the I ended up removing because with it in place, only 1-2 threads engaged in the lens housing. Be gentle and only finger tighten the lens portion. I would also strongly suggest buying a mirror, lens and tubing at the same time. lens: LSR-LEN18ZN5I mirror: LSR-MIR20MSI tubing: LSR-WTUBE5X8 This works well paired with at least a 950gph (2cfm) air pump. A small aquarium pump does not have the flow rate.
