Paint Booth - Bench Style

[CNCCAJUN]

I am in the process of designing & building a Bench Style Paint Booth. & Paint Room.

Looking for input, ideas, etc. . . .

Pictures attached of a booth are only to give an idea of what I am looking to build from a style standpoint.

I am not building my own to save dollars, but to get a booth more applicable to what we are doing, ?painting pieces of plasma cut sheet metal?.

What I have in mind is as described below:

* Constructed of 3/4? plywood & standard frame material. (2X4, 2X2, etc. . .) suggestions?

* Downdraft through real paint booth exhaust filters to the outside. (now I?m legal)

* Downdraft opening 60" wide X 40" deep - will accept ( 6 ) 20? X 20? filters.

* Dwyer manometer to monitor filter loading.

* Filters supported by angle iron grid & 2X4 Hog Wire.

* Access (front) opening 60" wide X 42" high.

* Grainger 7F930 - 12" Tubeaxial Fan with 3/4HP motor ? 2126 CFM @ 0.50? SP

* Fan will be mounted in rear of booth @ bottom connected to plenum sized 44? deep X 60? wide X 36? high.

* Thinking 2 or 3 horizontal 1" pipes running side to side @ top to hang projects to be painted from. (ideas?)

* Large gauge wire grid 40? X 60? for support of non-suspended projects.

* Lighting - (4) tube fluorescent bulb fixture located on exterior of top.

* Light will pass through recessed plate glass to keep light out of paint stream.

* Paint Booth will be located in a 7' X 8.5' room with filters for make-up / fresh air intake.

* 20" fan with filter in room wall to assist with make-up/fresh air intake.

Already received some excellent input from Marty . . .

Thanks in advance,
Steve in Louisiana

Looks like a good plan. Not sure where you are getting a tubeaxial fan with motor for $320, but jump on that deal!

eBay . . . are you looking for one?

It seems this particular 12" is being surplused out. Grainger tells me the model suffix designates an O.E.M. but identical to the rest in with the same model number.

It will be here tomorrow, hope it is not a P.O.S. . . . . supposed to be new in the box.

Sorry for the mislead, this was without motor. $293.00 with shipping.

I have a NIB Baldor - TEFC - 56 Frame - 3/4HP sitting here.

It is the same motor the OEM was using.

Received the fan, tested it . . . works perfect . . .

Where do you guys that paint, clear coat or rattle can do it?

It is cold here now and humidity goes up and down.

why not build a plenum and filter rack in the end of the 7x8.5 room for exhaust?
paint booth to me means filter inlet air (which you have) and exhaust fan
not sure what your going to accomplish with the additional box

Funny you say that, I came to the same conclusion last night when checking layout space . . .

Steve,

Have you considered Uni-Strut & custom, plasma-cut hangers instead of the pipe & wire method?

Great idea . . . Piece of UNISTRUT 60" long and make hangers that would accept wire or make custom holders that would be the actual hanger.

Thanks,
Steve

Here's the hangers I use, but you may have to tweak 'em a little.

Or, you may come up with an even better way! These work great & I like them a little tight.

I can't recall if I added a torch offset on these or not.

Haven't had to cut any in 5-6 yrs. I cut about 48 of 'em & still have most of 'em.

thanks!

Thank you very much . . . based on the dimensions I assume you are running low profile uni-strut.

Actually, no. The unistrut I use is basically square. I don't have access to it right now, but it's 1-1/2" or 1-5/8", as I recall. The low-pro unistrut would be okay, but not as strong. My rack is 10' wide with the uni-strut at approx. 5' off the ground.

I've hung 2 - 30" X 60" X 7awg. panels from it with no sag and no trouble. Two hangers per panel.

great minds think alike?

we have a bunch of various paint hooks of various lengths from 4'' to 18''
they are cheap on ebay too

Do you use UNI-Strut like SteelFX with your hooks also . . . or a round rod (pipe)?

I am thinking the UNI-Strut may eliminate accidental "unhooks" as you could have with a pipe . . .

Or combine a Uni-Strut hanger like SteelFX has designed with the hooks you are using . . .

uuuuuuum!

Thanks everybody,
Steve

now your just going to be jealous...
full truck size paint booth with a motorized conveyor 20 ft in the booth to 20 ft out of the booth
we can hang a full car in parts on it; paint half, rotate out and paint the other half
we use to do a lot of electrical control boxes when the economy was better, now we're too busy for that market



we also have a hydrographics area with eyelets on the wall.
2 hooks hang uni-strut across the area with more hooks on the uni-strut, the uni-strut can be removed in seconds
i wouldn't hang anything permanent
