Do I Need A Spray Booth

[Marc Stock]

I use a portable spray booth from expo tools. Not exacly the cheapest option but perfect for me as i use my office space to do my modeling in

The reason why there was no explosion could be that the combustion chamber (the plastic storage box) had no air following the spraying of the cellulose thinner into it. No air means no oxygen (or more accurately not enough oxygen concentration to allow combustion. This is because each inflammable gas or vapour has a minimum oxygen concentration needed to allow burning. (It also has a max. oxygen concentration beyond which burning will not occur but that's not relevant here).

I actually am aware of the need for oxygen to allow combustion Steve! The container wasn't hermetically sealed as should be apparent from my description. Therefore a sufficient proportion of the enclosed space was comprised of air.


Certainly there was enough oxygen within for the fumes to ignite when a lighted match was thrown into the container!

OK.

I am not at home and posting on my iPhone so I cannot provide a photo or links but I use a spray booth that does not require venting to the outside. As I use acrylics I am only concerned to scrub out the particles from the air and the carbon and other filters on my set up do just that. I have two units linked in series to create sufficient space to spray larger 1/32 scale aircraft but in fact just a single unit is enough for most models.


I will post more info next week when I get home with a link to the vendor.

I'm not going to get into the "will a home made one blow your house up discussion" but if I had enough room (or a man cave) I'd make one 100%.


As I am limited for time and space I purchased one off John and it works well for my 1/48 planes, I'd imagine that at 1/32 it would start to get a little cramped.

Here is what I use.


As mentioned there is an expansion unit available to link two or more together creating a larger spraying area for larger models though a single unit is enough for even most 1/32 aircraft. There is a cheaper version with a less powerful fan I would not recommend. Also as mentioned it does not need venting to the outside so is best used for acrylics. I am very pleased with it.

I went for one of these:

A very competitive price from John, and it ticks all the boxes for me. I won't be building anything huge, and I need something that can be packed away.
