spray booths

[Guest]

I was thinking it might be nice to make a fold up spraybooth that folds down into a bench top. It could sit ontop of the bench with a small edging to centralise it, the top would then lift with a piano hinge along the back edge and then the sides would fold up, with some kind of catch to latch them together. I didn't want to construct something which will take a lot of place to store the thing and sit gathering dust and looking unpleasant when it's not in use.

A lot of Graphic Artists use a spray filter that sits ontop of the bench and then has a clear perspex shield over the top. I was wondering how effective a rear extractor would be against a top mounted extractor? I would have thought it would be nearer the source of the paint particles and fumes etc.

Also If the extractor was mounted at a lower level to the back of the booth it could sit on the bench, requiring a much lighter structure to construct the booth. I was thinking along the lines of 3mm MDF, Birch Ply or Even Corriflute. I thought corriflute sheet would be a nice material as it's very light, cheap, and it's also semi translucent so would give a small amount of diffused light too.

This was the kind of thing I was thinking of (see pic below) with the cooker hood rigged up to the rear of the encluse on a kind of stand. The actual booth would be light weight as it wouldn't support the weight of the hood.

most of the ready-made spray booths have the extractor below them and a series of filters to make up the base. 9 times out of 10 the object you will be spraying will be on the base of the hood so you will be spraying down, so this sucks it straight away!

Volume of air shifted is the most important thing and a decent cooker hood is superb

we have a portable / fume cupboard here at work for use with solvents and Neat MEK, it is for the purposes of illustration like the spraybooth in post #16, but abit bigger,

it can also be used for spraying as well as solvent/ adhesives, we had it made by a local sheet metal company ( easy when the firm is paying i know- but not hugely expensive) but as MEK fumes are dense they fall, so at the back of this booth the tubing ( like a tumble dryer tube has a Y in it so it sucks from both the rear top panel but also from the base) really useful, but also advantageous as if you are about to spray paints, a minute of the fan running removes any dust build up since the last use on the base...... so prior to placing the item to be sprayed you can reduce any potential dust problems -so no or little dust in your fresh paint !

so if you are about to make your own spraybooth, with cooker hoods and tubing then consider having a lower and upper extraction point, its very useful, also by adjusting the fan speed you can also gain a type of electrostatic effect where you can actually suck paint into difficult to reach areas due to the base extraction airflow- the air movement carries the paint to lower surfaces...... this is not always desirable- it depends on the task ahead..... so the abilitiy to switch off this lower airflow is essential- on our system you just put the blanking cover on the Y output, its basically only drainpipe, but its a useful facility to have !

the motor/ fan we have is a plymo vent , basically just a big fan, the fabrication cost was under £300- its fairly lightweight sheet and plastic tubing but it works well and complies with C.O.S.H.H regulations which is a bonus !

I was thinking of designing the booth for easy storage as space is at a premium. The idea was that it sits on the benchtop and the top would latch on to the sides. Upon releasing the catches the sides could then be folded inwards and the back and top would then fold in half and be lowered down to fold flat making a reasoanbly easy to store flat box 50mm high or so. Obviously the cookerhood would have to be a seperate assembly or I might just go for some kind of fan and carbon filters. Hasn't taken a look at cookerhoods to see how easy fitting will be yet.

I just finished painting my home built spray booth. I'll post some images and give you an update on how it works later.

In the end I went with Nigel's suggestion of using a cooker hood extractor for extracting paint fumes.

I used some hardwood battens to make a frame and 9mm ply for the panels - it's built a bit like a wooden ****house but that was the only sheet material that came to hand!

It's very reassuring to hear that Nigel's guidance is still being put to good use.

I suspect that via this forum his advice will be used by many people for many years to come.

Yes Richard,we have a permanent reminder of everything he suggested and did within the forum,I do not think anything quite like this has happened to me on a forum before,it has left a big void,I just wish that I had met him and spoke to him more than I had done.

i found this forum by searching for airbrush tutorials...and obvisously came across Nigels.

so if it werent for Nigel, i might never have come across this forum and met him and all you other great people!!!

...Alan, cant wait to see pics of your "portable" spray booth.

i have not been that bold and still use my bodge job 3-sided wooden thing and a decent resperator with the highest grade filters avaliable!!

Hello

Sorry for digging up such an old thread, but i found this >Click< when doing some research.

Sorry guys if it has been posted before.

Wow ! that is pretty heavy stuff,you would never think there was so much to consider with a spray booth set up.

Anyone would think he was designing a ships A/C system!
