K40 Laser Air Exhaust Vent Full Bed Access, 2X Air Volume, (4th Gen) 40 Watt co2

40Watt k40 Laser engraving/cutting machine upgraded air vent, 4th generation short ram. Allows full bed access and expanded air exhaust volume. Now included, 1 air assist and 1 laser guide holder. Gives up-close to the bed ventilation without blocking any of the bed. About 2X increased air flow capacity over stock vent.

In comparison of having no vent and just the straight stock fan exhaust, I estimate it gives about a 20%-30% smoke exhaust evacuation gain. My bottom side scorch marks have seen a reduction when cutting 5mm wood in 2-3 passes on fairly high power at 60-65%. Fits easily through the back of the k40 laser machine and centers its self, the stock fan and fan slots will hold it in place without needing screws. If you have other aftermarket fan options and need it held in place, the air exhaust vent can bolted into the 4 pre drilled holes in the machine to still allow room for additional exhaust configurations (I cant guarantee what all aftermarket fan configurations will work but this fits great with the stock fan without even needing screws), it should work well with a few different aftermarket fan set ups, it works great with the stock fan also. The exhaust works well, I've been blasting through 5mm wood with it near 65% power and it seems my backside scorch marks are noticeably reduced or gone. .

It gives full access to the bed and places the ventilation directly at the end of the bed. PLA 3d print. There may be a few artifacts or striations across the shell, this is aesthetic only and doesn't effect performance, the print is pretty clean though. This print is fairly difficult to pull off and it takes a lot of material and a long time to complete. . ***If your K40 software expired and you don't want to buy CorelDraw, look up "k40 whisperer" free software, it works great*** If you need an air brush compressor look into the harbor freight model, its been great to me and very quiet.

*****Be careful what material you laser, some materials and most plastics create chlorine gas when lasered, if you breath chlorine gas it will mess you up.***** 30 days postmarked (after received) return policy, item must be returned in same or very similar condition as received.
