I have recently bought a Chinese laser cutting machine which works quite well. Here is a picture of the machine:
However, when cutting plywood or acrylic, the smell is quite high and I believe it’s not healthy to breathe the vapors.
So I’d like to change or upgrade the exhaust fan. The wall output is 2.5m higher, as the machine is undergournd.
The machine is equiped with a small fan, see below:
and I don’t think it’s powerful enough.
The output and hose diameter is 6" - 15cm.
I’d like some advice before I buy the new fan. My concerns are:
- Should I place the fan at the rear exit of the machine, at the end of the long pipe or in between (eg one piece of pipe, the new fan and the rest of the pipe going up outside) ?
- What power should I choose to expel the gases to this height, while keeping a low noise ?
- Should I remove the existing fan, as the helix may prevent the air from flowing outside, or not?
I’m thinking of buying this kind of fan:
The price is around 80€. Any advice on this kind of product?
Thanks a lot for your help
