A suction head mounted on the front of a blue laser engraver to blow the exhaust out of the window :)
It's mounted on the front of the 2500 mW 445nm laser with 4 M3 screws. The adapter for the hose fits to Festool D27 hose (e.g. https://www.ebay.de/itm/Saugschlauch-27-mm-Absaug-Schlauch-Meterware-Ersatz-f-Festool-D-27-452384-D27/163385424393?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649)
Currently I use a 120mm 12V fan which works quite well.
The hight of the suction head can be adjusted as well as the focus of the laser.
Air assist from the other side is planned....
