DIY Fume exttraction

Nov 23, 2005 13 Replies

Any ideas for a DIY fume extraction system? Mainly solder fumes, sometimes glue or paint.



Extraction can be to the outside so not too bothered about filtration in this case



Commercial systems start at around =A3500+VAT, other than the cheap fan and carbon filter gizmos which cost about =A350 and which I've found to be pretty useless.



My main problem is identifying the type of pump required, ideally not too noisy.

Cooker hood with an external vent kit?

Get a PC Type fan and wire it to a "wall wart" type of power supply.

Bolt a couple of finger guards to the fan, one either side. On the 'blow' side of the fan sandwich a piece of kitchen extractor filter* between the fan and the guard.

(*Charcoal type)

If it's to make you breath easier, you may consider doing it the other way round. A mask, with supplied air.

This can be as simple as a hosepipe, with a "matress inflator" type blower at the far end.

I'd suggest it's time to take your own mask off now, it's been on a little too long!

It was some odd vi thing. I think it's typoing i, and not noticing the effect when hitting 'esc'.

.....with an orange in the mouth, crocodile clips on the nipples etc?

Strictly optional.

I superseded that moments after it got posted. Oh well.

I use an old bathroom extractor fan and hose, boot sale £3 :-)

How close to the work do you have to get it to be effective? I have one of the fan & filter types but most of the fumes go straight up unless the unit is so close that you cannot then get to whatever you're working on.

I would also like something that can be adapted to use a tip extractor attached to the soldering iron (feature creep has started).

I use it when Brazing, I seem allergic to the flux fumes they makes me sneeze. Fan is mounted in a window with 150mm hose connected from the suck side to a metal funnel, which is welded on to an anglepoise lamp base. Works fine at about 18ins from the work piece, but I can't see there being enough suction for small bore pipe that would actually fit on a soldering iron, You'll need a Dyson for that.

Brazing flux may contains fluorides, heating which is a damn good way to manufacture hydrofluoric acid! I am _very_ cautious with silver soldering fluxes and ventilation.

OTOH, I still love the smell of resin flux. Nearly as good as warm paraffin wax with a tang of ozone.

nice, no wonder my nose doesn't like it.
