The Xtool S1 internal fan is in most cases inadequate for cutting and engraving wood. It does not clear the machine of smoke, firstly because it does not have enough suction, and secondly because it does not run long enough after the laser turns off. My workroom always stank of smoke until I added the IF2. Now the air quality is much better. The IF2 removes all the smoke from the machine, and it runs long enough after the laser turns off to also clear the retractable air duct I use. I no longer get smoke in the room when I open the machine or retract the duct. I think that this is an essential piece of kit. It is well made and does the job perfectly. I am very happy to recommend it.

Excellent piece of kit, does exactly what it states

Purchased to replace the inline fan I bought off Amazon. This thing is amazing. Awesome speed and fume extraction. Brilliant piece of kit

Great bit of kit really easy to setup and works like a dream full automatically. Does a great job extracting everything and keeps the air in the house nice and free from fumes and smells.

This really improves the extraction of smoke and other bits from engraving and embossing. In my set up I have a long run of exhaust pipe and even with this length this product makes sure everything is sucked out from the F1 and taken away outside. I also like that I automatically starts and stops with the F1 and alters its power based on the material you are using. Would highly recommend.
