Powder-coat booth

[Davek0974]

Hi all,

I do a fair bit of powder-coat at home, I use a lashed-up booth of about 30" x 30" x 30" it has a recirculating cooker hood on top which is basically a fan with a filter cloth in front of it.

It works well but is heavy on filters and they don't last long.

Is there something better i can put together? I can't blow it out/extract it as it's a residential area and risk a mess.

Looking for ideas

Would blowing the exhaust (pre filter) through a water curtain(imagine a waterfall) cut down on the amount of paint reaching the filter?

Hi

probably would but would have to look into how to make it work on a small scale setup

Its an idea though

I'm thinking a small pond pump out of a settling tank/sump.

I watched one of those How's It Done type affairs and they had the spray plant at BMW (IIRC) and it was a wall at perhaps 85% slant with the powder sprayed toward it --> ___/ with water flowing down it as bigegg suggests. Flow was minimal but the setup had essentially replaced the old filtration system it had proved so efficient.

do it outside the powder will just blow away in a breeze like dust (like I do)

my setup is smaller than yours, but I use a plastic tub on its side

the vast majority of the powder remains in the plastic tub

when I've finished I brush out the powder and store the powder coating equipment in the tub.

I bring the coated parts inside and bake them in the oven in my kitchen

My set up is similar to optima but I use a cardboard box rather than a plastic one. I then use a halogen oven.

you need a bigger water pump than you think

I was actually thinking extracting as normal, and making a small waterfall filter.


Tbh, my original comment was a bit off-the-wall. I didn't even realise that they were already a thing

Sounds like a job for a cyclone type separator. http://www.tmart.com/SN50-High-Effi...MIssf7172t2AIV6JPtCh2BUQBvEAQYBSABEgKjtvD_BwE
