Anyway to SAFELY not vent outside?

Posted by rockythegoat on Friday, July 15, 2005 10:41 AM

I have a booth (Paasche) that is vented outside. Would like to rearrange my hobby room, which would move the booth too far away for outside venting. (Would be about a 17 foot run, with 3- 90 degree elbows).

Any way to build/cobble together a vent/filter box that I could attach to the booth exhaust? Something similar to the style of stove vents that exhaust inside the house via a charcoal filter. I normally use acrylics, but, do use solvent based stuff now and then.

I'ma thinkin', exhausting into a metal box, that has a furnace-type pre-filter, which leads to the final filters which would be face respirator type organic filters installed backwards. (The side which would normally point towards your face, will be exposed to the room. The normal "outside" of the filter, would face inside the box so the air is filtered.)

Thoughts?

Respirator filters are going to be too small unless you somehow partially disassemble them... the small ports on the back are going to be too small to let the required amount of air through.

I would recommend trying to pick up middle/charcoal filter package for an Artograph spray system, and then trying to adapt that:

The filters come in packs of 4; item 225-317 will be 15"x20"; 22 225347 will be 15"x30"

ck: thanks for the reply and the supplier info.

any particular thoughts on plan B, running 4 inch ducts 17 ft with 3 90's? it would likely make sense to use smooth duct as opposed to flex pipe, as its more "airflow" friendly.

You'll definately want to go with the smooth duct, which will probably be cheaper than the filters (which will need to be replaced). The concern is going to be whether or not your fan/motor is going to be powerful enough to overcome the resistance in the pipe and push enough air through.

I've referred people to this site a few times before:

I haven't checked the accuracy of his numbers, but I believe his approach is correct.

You never said what paints you are using?

My primary paints are Badger ModelFlex and Future overcoat. BUT, maybe 15% of my painting uses rattle cans, (Testors MM and hardware store stuff) for some things (primer coats, special colors, etc). So, I do have to worry about the solvent fumes getting into the room air.

I will try that guy's site and see what is says.

I've sent an inquiry off to Paasche to see what they say, both for room venting and the 17 foot run using the HSSB Spray Booth. (What I have.) I'll post their response here when and if I get it.

Thanks!

Make your decision based on the most important factor. YOUR HEALTH ! The fumes from those solvents is just too potent to take a chance on doing serious damage to your lungs. Even acrylics have some chemicals in them that are not very condusive to good health.

Here is the answer to the same question from Paasche, the maker of my paint booth. Just a little FYI to all:

"That is a long way to run the duct with 3 turns. If you only had 1 turn it would most likely be fine but the 3 turns may add to much resistance. It won't hurt to set it up and compare the air flow before and after hooking up the duct."

I think a "Pat-On-The-Back" to Paasche for getting back so quick is in order.

Yardbird: I agree with your assessment. I've never been a fan of the venting into the room thing. Guess that's why I went through the hassle of installing ductwork for my kitchen stove hood when we remodeled. That was a fun job... Dead [xx(]

Guess I'll live where the booth is now, see what I can do there to steal some more room.

Thanks all for your comments.

Hi ya,

I have the same booth at home. My exhaust tube is about 20 feet long with 1 90 degree bend. I have not notice any decrease in performance since I switched from a 10 foot run to a 20 feet run.

Also, I always use a three stage respirator when spraying (even acrylics) and after spraying, I allow my booth to run for about 10 minutes to further filter any fumes in the air. I also leave the room for that 10 minutes.

You could say "I enjoy my health".

Good luck,
Jesse

Jesse: Thanks for the info. I hate to loose too much effeciency with this booth, as it really moves the air. I've had some smelly stuff spraying in there and have never had a problem with fumes in the room. It's a real nice booth. My only complaints would be, and both are minor, is the thing weighs a ton which is limiting me a bit on where I want to put it (shelf which has some weight on it now) and there is no provision for lighting.

Actually, now that I've said it, how do you handle the lighting issue? I have a swingarm lamp pointing in, but, it gets in the way and throws pretty harsh shadows.

If you consider it a real problem, I have seen sections of tubing (4" is the smallest)which have a small fan with a non-explosive motor built into them which are used to boost the airpressure in long runs. They're set up to turn on when you turn on the blower in your spray booth. Check with someone like Granger or your local heater/air conditioner shop.

Hi rockythegoat,

I was wondering what you ended up going with to possibly not vent your spray booth? Having read over 100 threads on various suggestions for spray booths here, I like the larger size of the Pace booth (5" deeper, also the built in lights) and how it looks more enclosed than the Artograph 1530, so if I wanted to use spray paint cans, it won't end up everywhere as much.

In an aparment and with a cat running around, I also don't have as easy of a time to exhaust the fumes so I was wondering if any of you have purchased and tried the Artograph mid and polyester/charcoal filter and stuck that in the Pace Peace Keeper Deluxe? Would that work safely and what size is the filter in the Peace Keeper Deluxe?

I figure when we have a larger place, I can exhaust the fumes outside my house/work area and I like the larger size, lamps, more enclosed looking pics of the Pace. The 1530 does seem to have a more powerful fan (370 vs. 265 cfms) though.

Thanks for any thoughts on this option and all the previous suggestions from all the other forum members.
