Hey everyone, happy holidays to all.

I have an issue with my garage and I sure could use yalls help.
The issue is, the garage sweat's bad. All my tools the floor, just about anything that you touch has moisture on it. What can I do to eliminate this problem? The shop is completely insulated.
It only happens in the winter.

The other thing that I could use help on is how to run the plumbing (AIR) through out the shop. Does anyone have a drawing on how the airline should be ran?
What is the best thing to use for the main line?
What is a good in-line water/oil seperator?

Tim.

sounds like you need a dehumidifier. should be able to find a decent one at lowes/home depot

71tahoe · 01-02-2009, 11:53 PM

Trick question?

Southeast Texas=gulf moisture.

Your well insulated shop traps moisture in the air and still gets cold enough for everything to reach the dew point.

The only things I can think of are heat it or dehimidify it or both.

Question 3.

I used 3/4 schedule 40 pvc, adapters from HD and quick connects from various and sundry places.

Question 4.

No idea on a good drier.

Well. I will give you a link to a place i have bought stuff from.

In their catalogs they have airline routing diagrams.

And tons of cool stuff to buy too.

http://www.tptools.com/

I am not affiliated with them. Order a catalog. Just had good luck buying from them. Great service.

**El Jay** · 01-03-2009, 12:42 AM

Personally, I would avoid PVC.

If that stuff decides to come apart because of some minor damage, we're talking "mucho shrapnel", and very possibly some serious bodily harm.

Spend a few extra $'s & go with copper.

Just my .02.

with that being said. I offen wonder if pex can be used for air. its amazingly strong. and a hell of alot cheaper then copper! lol

**El Jay** · 01-03-2009, 01:48 AM

I have to be honest, I 'm not @ all familiar with pex, so I can't comment.

I just know that seemingly minor damage to PCV has the potential to become disastrous.

corn · 01-03-2009, 02:25 AM

Could try one of these.

Have to agree.
You might want to consider an exhaust fan. Plus it will help with fumes

70GMCer · 01-03-2009, 08:05 AM

If you are have condensation problems, going to any kind of metal piping, (copper or otherwise) for your compressor, will create a lot of water inside that piping. IMO

TennesseeZ · 01-03-2009, 08:17 AM

PVC piping comes in more than one thickness (schedule). I agree, I'd stay away from that real thin stuff you find in the hardware airplane hangers, get some sch 40 PVC and fittings from a plumbing supply or go with black iron threaded pipe.

As for the sweating issue, what is your shob built of? Is it freestanding, a basement, or any other type construction that could be contributing to the moisture issue?

ETsC10 · 01-03-2009, 02:09 PM

Maybe your shop is too well insulated combined with no or poor ventilation.

Warm inside air can hold lots more moisture...mixing it with outside (colder) air
can often lower the inside humidity plus shift where the dew point is reached.

Sounds kinda silly, but try opening the doors every few days.

I live near an airport and have a sound abated/super insulated house.
To help prevent humidity problems, the house has an automatic vent system
that recirculates the inside and outside air.

...that's my shot in the dark...

elkynova · 01-03-2009, 02:59 PM

I had that problem in my shop after super insulating it. You need to have some sort of ventilation system or just crack a window and leave it open, that should help. I used 1/2 inch sch 80 pvc more than 15 years ago for my air compressor lines. I have a 5hp 60 gallon compressor and have never had a single problem. PVC is fine as long as it does not have exposure to direct sunlight. I would definately use sch 80. Good luck

beautimus · 01-04-2009, 06:51 AM

in reguards to the condensation problem, the advice your getting in the rsponses above is golden. one note on the humidifier, get one of those that has an adapter for a garden hose. when you get it, set it to run continously for a couple of days to get the moisture out of the air.run the garden hose to a drain or pipe it out thru the wall. then set the setpoint to about 50 percent humidity and let it cycle on and off as needed. you won't believe how dry your shop will stay, and how much water it will extract over time.

As for the air lines, pvc will work, but the glue joints don't like some compressor oils. it can weaken the glue over time. plus if you get the condensation stopped you wouldn't have to worry about metal air lines dripping. best of luck to you.

cdowns · 01-04-2009, 08:54 AM

was a vapor barrier used under the slab? you might consider sealing the concrete floor would help a bit

Tim's68 · 02-06-2009, 09:48 PM

Hey guys, first I would like to say thanks for all the input. Second sorry for taking so long to saying thanks. Some of you guys posted up a long time ago and again I apoligize for not responding. Im 50 years old and we just (July16) adopted a new born child, need I say more????
All the answers that you gave is what I figured, just wanted to make sure.
I have two exhaust fans on the back wall, do you think if I put a timer on one of the fans and have it to come on say like at 6 am 1pm 6pm 12am.that would solve my issues????? Or at least help ????
And by the way Corn, the AX stuff helped but it did'nt solve my problem.

So much for all that, anyone have pictures of their winter projects that they would like to share?
I had full intension to be furthur ahead than I am but to be honest I have done NOTHING.
Im still trying to figure out how to do a back half on my truck (68 short fleet) to run 33X21.50tires. Got any clues??? Anyone in the Houston area willing to help me out?
I under stand the cutting of the rearend, 4link, coil overs, I just dont know the dimensions on the frame as far as how / where to cut it.
I dont have alot of money to pay you but I could sure take you on a good surf fishing trip ......................... if you like saltwater fishing?
Well, the new addition is crying so I must go do my other duties.
And again,thaks for all your help.

Tim.
