Compressed air bulkhead fitting outside wall of house.

Picture of Compressed air bulkhead fitting outside wall of house.
Ever since I purchased my house I have been wishing for a compressed air line on the outside of the house. I do all my own automotive repairs, and live in the rust belt, so an impact wrench is a must. My house is 125 years old, and in need of fixing up, as every old home is. I am a hobby woodworker, so pneumatic nailer and stapler use is a common weekend activity.  I use a compressed air a lot. So having an air outlet located in the place where you use it most often is a wonderful thing to have. Especially when it would mean not uncoiling and running hoses on ridiculous  paths through your house every time you would like to do any project.

This project is all about convenience. My compressor lives in the basement, near my electrical panel, which makes sense as it is a 220 volt compressor, and its big and heavy and hard to move. Dedicated 220 volt outlets are expensive. Air hoses are cheap. So the compressor lives its life in one place.

So the best plan would be to just mount some kind of airline permanently on the outside of my house, with quick connector fitting, to the place where most projects happen. Just power up the compressor in the basement, hook up your airline outside and you are off and working. Sounds great, yes? But his brings up a few issues of its own.

1) Any work you do on a house you own should be well crafted, and designed to last a while and not rust or make a mess.

2) It should be designed with weather in mind, and should not compromise the envelope of your house.

3) If is mounted in a place where you can see it, it should look nice, and not like a large kluged together eyesore

I spent a while trying to figure this project out to make it look good. Every time I would stop at gas station that had a repair garage I would look and see if they had an airline outside and how it was installed.  Most of them were horribly done. So the goal was to make this project look nice and get the number of pieces down to a bare minimum. Standard design principle: Less Parts = Better Design.  And Make it weather tight. And make it look nice. And get it approved by my wife. This last part is important. This is what I came up with.

I imagine you have to run a lot of hose if you're running an air line source from a fixed position. How are you dealing with the condensation/moisture that accumulates due to the hose length.

Nice Job! I'm sure you'll enjoy this for many, many years.
Nice. Really elegant solution. Couldn't you have previously poked it out of the window in the above picture though?

As with many old houses, the previous owners made some decisions that I would not have. Like taking the semi-rotten basement windows and sealing them in place with spray foam, and then someone else came along and screwed and caulked single pane storm windows over them. Rendering them all doubly non-operable. Not the best solution, compared to replacing them with newer windows. But it works well enough to be fairly low on the list of things on this house that need refurbishment.

well done! I've always had the luxury of a garage when doing my car work, but this is a fantastic fix to a problem a lot of people have. Thanks for sharing!

Thank you. I had been trying to figure it out for a while. I tried searching for a good solution on the internet, I found a lot of people who where trying to do something like this, or build something like this, but no one had a found a nice solution. Once it was figured out the execution was simple, and I hope worth sharing with the other shade tree mechanics, professional mechanics, woodworkers, contractors, propeller heads, tinkerers, etc, etc, out there.
