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.
Step 1: Why This Needed to Be Done.
Not in least, because of the design of the house, it requires running an air hose on the following path. From the compressor, across the furnace room, out the door, through the workshop, past the basement stairs, across the laundry room out through the door at the bottom of the bulkhead (hatchway to some) up the stairs through the door at the top of the bulkhead around the garden, back down the side of the house, and to the driveway. Total length = 100+ feet. Its a pain, it takes time, you have to leave all the doors open, there are lots of places to trip over the hose. And when you are done, you get to pack it all back up again. Its just a bad way if doing things. So bad its almost comical, I sketched up a basic not to scale layout to explain it, Yes its that crazy of a route. Something must be done.
Step 2: Gather the Parts.
1 - 1/2" NPT pipe flange
1 - 1/2" NPT Lapp Brand Waterproof Skintop Cable Strain Relief.
1 - 1/4" NPT pipe nipple long enough to get through your wall, plus a few inches, in my case 18"
1 - 1/4" NPT street elbow.
1 - 1/4" Female air line quick connect fitting.
1 - 1/4" Male air line quick connect fitting. (not pictured here)
1 - Teflon thread sealant tape (not pictured here)
1 - Mounting Screws for your pipe flange (sizes vary)
I tried to keep the parts count as low as possible to keep with the clean look. The pipe flange, nipple, and fittings I got from a company online www.pexsupply.com as no local store carried much in the way of black iron pipe in the 1/4" size. The air fittings are from the local home improvement store. The cable strain relief something I had, but can be purchased from an online supplier like Allied Electronics, or you may find something like it at a local electrical supply house. Note of caution: Many of the 1/2" strain releifs I tried did not have a large enough opening for the 1/4" pipe to pass through. You can easily step up to a 3/4" NPT strain relief and pipe flange to make your life easier. The 1/2 version I found just barely fit the 1/4" pipe I was using. I could have gone to a 3/4" pipe flange and strain relief, but smaller flange looked better where it was being mounted.
