Laser exhaust

<< < (3/3)

No. It's not weatherproof and making it so outside, with power and everything through the walls, isn't going to run.

Its is one of these and I think the problem is where the exhaust tube attaches to the fan. It's shaped metal and there is no gasket between that and the fan body. Should've thought of that when I put it in, but I was concentrating on making the tube-to-duct joint airtight. That bit's OK :)

Fixed. The issue was cause by the hole in the fan housing for the cable feed-through. I neglected to take a photo and ain't going to pull it all apart again just for that, so the attached image is a generic fan (clearly not a mains one!) which shows what the problem was. Being on the downwind side, it's an extra exit to blow air out of.
