Ideally, a turbine is outside.JBeasty wrote:Yeah, after thinking about it, the fan idea makes the most sense for me. Cheap, easy and relatively quiet. My shop-vac is so loud I wear ear plugs when I run it.
As those are providing some aspiration à few meters of tubing can be envisaged without too much losses
It is not easy for me due to the walls, so my solution is to create a heavy box with isolation so the noise lower.
The silencer is also effective.
To help à fan, make it more efficient, some length of tubing front and back will help a lot, there are much turbulences around fans the aspiration zone and level is quite small in the end.
I use an "industrial" type in a door I added to the entry door, I could see how different the result is with the tubing (thin aluminium foil) front and back.
Suddenly my cell phone atmospheric pressure detector did notice something (I don't remind, 1-2bar I think), and the whole piece is not hermetic at all.
A few computation volume vs flow, may be useful.
If not too noisy those small units that are intended to be plug on a supple tubing, may do the job too (they are designed to create a good aspiration level unlike fans )
The formulas are easy to find, some on the turbine and fan makers, to choose a model depending of the use.
For a paint booth you look for 0.5m/sec air displacement.
Fumes rise so it may be different, I have a vertical flow (not very strong) and aspiration at floor level.

Put the fan behind you, it will be much more effective. Also, if you line it up right, it will keep the fogging in your welding helmet to a minimum. stick welding is pretty immune to wind and drafts, so let it rip.
