Kit de Arrefecimento por Ar Twotrees 500W para CNC Routers

plus: relative quiet, strong airflow possible
minus: housing not excact (small gap), fastening not optimal (screws in full material would be better)
idea: let the ventilator turn to the other way round (smoke suction)

Includes everything needed for installation except assembly instructions. They can be found on YouTube. Works well. The power cord needs to be placed (hung)far enough above the router to allow free movement of the spindle.

Surprisingly high airflow for such a small device.

j'ai acheter la cnc ttc450 ultra avec le kit de refroidissement+ d'autres accessoires tout est parfait sauf une choses ils existent des francais qui achètent ce genre de machine alors pourquoi je retrouve dans le mode d'emploi la langue anglaise et pas la langue francaise pour une grosse machine comme celle ci

I bought my machines and parts directly from TTC. Their support is excellent — very responsive and helpful. Shipping from China to the Netherlands was fast and smooth. The machines themselves are also very good. I did have one small issue with the Z-axis: the screen was a bit loose, probably due to transport, which caused a Z-drop mid-process. I tightened it back up and it's working perfectly again. So my only advice: double-check the bolts before starting a run. I’ll definitely buy from them again in the future!
