Adhesive fume extraction

[Paul_]

Evening all,

I'm coming to the end of a very long shop re-fit which has involved enclosing all repair machinery into a workshop within my shop, I have a window which has worked perfectly for fume ventaltion in the smmer months but I need to get organised for winter (when the window will need to be closed more)

I know I can buy specialist work stations that have ventaltion systems but I want to fit an extractor fan that vents from floor level to the outside. My question is, does anyone have a simular set up and have any advice?

I have a fan simular to this on my laser engraver which is perfect for fumes but would this handle adhesive fumes?

Hey Paul,

My daughter has a system in here training academy to extract fumes while teaching Acrylic Nails etc. It's portable and uses activated charcoal and can be vented via a tube through a window if needed. I'll ask her where she got it and let you know.

Cheers Martin, much appreciated.

You would need to consider fire risk assessment before installing D.I.Y. ventilation on flammable fumes.

Correct me if I am wrong but having done some research the fumes are VERY unlikely to ignite, unless contained in an air tight area. The fact we have air flow through the workshop from a doorway and window (plus vent above the window when closed) will allow the fumes to be diluted to any problem there may of been. 

Please tell if i am wrong as I need to get this right. I have learned that i'll need to filter through a carbon filter to reduce the smell to the surrounding area.

Cheers, Paul

I assumed your intention was to use some type of ducting to expel the fumes to open air, in which case the choice of motor could be important.

That's exactly what i orginally wanted to do, do you mean the fumes would be dangerous at the point they pass through the fan? My belief is that as the fumes will be mixed with oxagen (and so diluted) there should be no issues. Am I wrong? Appreciate your feedback.

Mixing flammable gases with oxygen can’t be a good idea surely?

[Flash]

It's something to do with the electric motor creating sparks as it turns, flammable gases and sparks are not a good idea. I understand there are motors that don't create sparks but I am no expert.

I think the concentration of flammable fumes that would be on a workbench would be unlikely to ignite from a motor, I have a sawdust extractor, nothing more dangerous than dust but in 15 years bever been blown up

[autolock]

I bought a unit off widespread solutions a few years ago ,and was designed to pull fumes through charcoal filter then back into The workspace which in fairness did work well but I opted for option of after going through the filters ducting it outside and that worked perfectly with no fumes outside either

[Trev]

Both sawdust and flour are known to be explosive when suspended in air and have caused many industrial accidents, therefore I would expect an extractor designed for extracting sawdust to be a sensible option for extracting explosive fumes.

[Flash]

Depends on the type of motor, 'unlikely to ignite" doesn't really cut it in a fire risk assessment.

[Mick Friend]

for the vapour to ignite it would need to be in the ignition range ie  

Petrol Vapour

1.2% volume in air

560 °C ignition temp

[Mick Friend]

so at that you would reek of it, so your solvent base being sucked out would be very very weak, but as was said you need to have specific info on the Vapour density and flash point

Hi all did you get any further with this project? Im also keen to add extra extraction into my small shop and would really appreciate any tips. Thanks, Alex
