This adapter fits DIRECTLY onto the back of the XTOOL F1 ULTRA (NOT the F2 Ultra), and it replaces the existing fan grill for the lowest profile 90 degree transition. You reuse the existing hardware. The round end then attaches to the BLACK flexible xTool hose. 

Build your custom smoke and fume extraction system with hose adapters allowing you to transition between various size hoses.

This part allows you to make a tight 90 degree transition at the back of the XTOOL F1 ULTRA (NOT DIRECTLY COMPATIBLE WITH inlet/outlet of the xTool IF2, and AP2! you can find that one here) for the purpose of smoke and fume extraction of your laser cutter and engraver. The flexible black xTool hose then attaches to this adapter and then you can attach the hose to the AP2 / IF2 etc. 

Certain laser machines / enclosures such as the ones from XTOOL typically include some length of 3 inch flexible hose. The bend radius of this hose is quite large and if your enclosure / machine is close to a wall you may need a tighter bend. This part makes the bend tight and low profile.

If you are looking for examples of inline fans that are commonly used for this application, see the links below. I would highly recommend the xTool Inline Fan 2 (IF2) or Air Filter 2 (AP2) as they interfaces with the xTool F1 Ultra and are very powerful. Check the link below for the best price from xTool.

 What is included:
