Outside Compressed Air Outlet Ideas?

[Metal-Marc]

Any idea or suggestion on how to have a compress air outlet outside my garage?

The first thing that came to mind was copper, but copper will transfer cold/heat inside and maybe cause condensations inside the wall.

Inside wall is roxul, a 6 mil plastic and sheetrock.Garage has a minisplit, so is heated in the winter and cooled in the summer.

Who has done this?

I made a pass-thru with 3” pvc pipe capped on the outside with a weathertight cover (from a 240v outdoor receptacle). When I needed air outside, I would push out a 3’ whip of permanently coupled 3/8 hose. The rest of the time the hose would be pulled in to thaw and keep out of the sun. 24 years so far, same whip.

I used copper in my old garage with an outlet weatherproof cover…no issues. In my new shop which is stone and log siding and didn’t want that box…so I did this. Reaches most of my buildings and exterior walls.

 

[Jeff Ivers]

10 years ago, I installed a through the wall feed for outside air and have had no problems with it. I used a brass ****** and associated fittings. I documented it in my DIY Shop thread.

I stubbed 3/4 copper thru the wall and sealed the exterior penetration, this is on a pole building. The wall was insulated with fiberglass batt insulation.

Got a 100' hose on a reel that hangs on the inside of one of my doors. Going to use one of these for outside access right under it. Open the hatch and poke the hose out and pull as required.

I bought one of those intending to use it. IMHO, it’s flimsy and I didnt use it.

Which 240v cover did you use?

 

[DGersic]

I put in pass-through holes using electrical boxes and outdoor covers.

Maybe something like this? Won't be as flush, but it won't be flimsy and should seal decently

Lots of great ideas.

This got me thinking. Maybe a rubber hose throught the wall connected to a 90° elbow and a quick connect?

I used a galvanized cast iron outdoor weathertight-ish cover I found in an industrial dumpster, but if I had to buy one now, I would use something like this:

but copper will transfer cold/heat inside and maybe cause condensations inside the wall.

I really think you're overthinking this. hose bibs are installed on virtually every house with a hole drilled thru the exterior wall with no issues.

 

[PCustoms]

Sleeve the copper in a section of PVC pipe and then fill the pipe with foam.

Even if there is condensation at that point it can't go anywhere.

But

How often do you really need air outside?

 

[Yellerdog]

Overthinking this, just run a pipe through the wall with quick connect fitting on the outside. Pumped gas after school and this was out setup in the 80’s, was still there when the building got torn down 4-5 years ago.

 

[Metal-Marc]

How often do you really need air outside?

Often enough I guess. When I air my tires, swap tires with the air jack, any other construction work which require a nail gun, blow gun.

 

[ericm]

How often do you really need air outside?

Pretty often. Blowing off chainsaws and tractors. I don't want the dirt inside. Airing up a vehicle that's not pulled into the garage. Thanks for all the tips, I'm planning a couple external air outlets on my shop.

 

[Jeff Ivers]

One of the things that I did not mention in my earlier post is that I am a firm believer that the air pressure to one's lines should be turned off except when you are actually using air. I have a quarter turn shutoff between my compressor and my air lines that supply the shop and the outside. Since the amount of time I use air is much less than the amount of time when I don't, consideration of condensation in the wall was absolutely never an issue.

 

[T444e]

How often do you run warm/hot water during winter through your hose bib?

Not warm/hot water, but my tap water is low 50s and use the hose bibb several times throughout the winter (SE WI) and daily when I had a dog. Never a concern. More of a concern about condensation running sprinklers on the hose in the summer. I wouldn't worry about what little condensation may possibly come off an air line.

Who has done this?

I have a standard Milton "M" on the north outside of the shop since 1989. It works,

Pretty often. Mostly the air blow gun, for cleaning off things that I don’t want to bring in or put away dirty. Tablesaw, miter saw, various sanders, routers.

Nail gun got used a bunch while building my shed, and recently on repairs.

 

[The Cobbler]

I don't understand the question. warm/hot water isn't going to condense . case in point, look at copper water lines in a house, the hot line is always less discoloured

Common occurrence to use compressed air out side. Now if I could fit multiple vehicles (hell, if I could fit just one, or even the lawn tractor ) and had room to work on my projects, disregarding all the combustibles and combustible finishes, my need for outdoor compressed air would be near zero. I still need to clear enough room to get the lawn tractor in the shed and attach the snowblower.

 

[T444e]

This is my exterior connection. The copper is sweated to the brass plate (1/4" thick). Didn't want to stress the sealant on the penetration. I had to offset around the inlet piping to the regulator. The exterior connection was added years after the original install, got sick of having to open the overhead door in winter when needing CA outside. The black hose goes to a hose reel between the doors. Love the reel (another afterthought after original install), but again don't want to open the door in winter to use it.

 

[HPRifleman]

Would it be easier to just have a portable compressor (pancake or roller) that could be taken outside when air was needed?

Or a hose?

 

[jstroede]

Here was my solution. I wanted air and water in my back yard in my garden/patio area. It has worked well for me, though I do drain water in the winter. The water actually is connected near the floor with pex to a T installed on the spigot I have in my garage.

 

[steve308]

Am I the first in to suggest PVC?

 

[Tbender78]

I just used the standard brass connectors on the side of my house at the driveway. Wifey can pull up, turn on the compressor from the outside switch and air up whatever she needs. No need to bother me.

 

[Fav Onefour]

Somewhat related, I ran an air line through the attic out to the garage. I'm in cold climate.
I used copper and had concerns about condensation. The line in the attic is sloped to the garage entry point. I did a fitting similar to gas line sediment trap at the lowest point with a ball valve on the bottom end.
My compressor is usually shut down between projects. I open the ball valve and drain when I shut down the compressor. There isn't much condensate with seventy feet of 1/2" line through the attic. On occasion I'll see a few drip bubbles.

Hose? This is GJ the solution has to be to buy a second outdoor compressor...........

Too many people with too much time on their hands.

I either run the 50' hose outside through the man door or grab the pancake and 10' hose and go for a walk. Depends what/where is flat.

Seems a bit through the wall you still have to go in and get a hose, unless you leave it outside all the time. If so, I then ask:

• Why haven't you fixed the leak yet
• Why don't you have a vintage 1950 gas station air station

Air hose? It ain't the 90's anymore.. Grab the cordless inflator or impact ratchet.

About 18ish feet of sloped exposed 1/2 copper to my reel. I did put a drain leg like mentioned earlier, but zero problems in 8 years of VT Winters. Gets used every time I plow to blow off truck and any other **** that comes in including mower in summer. My blow guns that are kept outside have frozen up but never the line. Don't overthink this.

 

[NUTTSGT]

I used a hole in the back wall below the compressor and covered it with outdoor plug cover.
Once I added the shed over the back wall I permanently plumbed it in the shed. Now I just open the shed door and there's a quick connect.

That sounds horrible, how do you ever get anything done using such simple solutions?

100%!

Did this, parked right beside barn. Handy as heck. It probably sees more use than my shop compressor. 185cfm is a joy. I may reverse plumb my indoor lines to use the diesel compressor when heavy cabinet sandblasting inside ( 25 ish cfm stuff) as if never been thrilled with my 80g 2 stage

 

[larry4406]

I ran copper pipe inside garage walls.

Transitioned to threaded via female adapter. Drilled masonry. Stubbed out with galvanized ******. Reducing elbow pointed down to quick connect. Duct seal around pipe at brick.

10 years on….

Looks pretty good Larry. How does the duct seal hold up to the weather ?

That duct seal is untouched since I put it on about 10 years ago.

Roll a snake, put ends down so seam is at bottom, and make it look nice and work the seam to seal.
