Plumbing for air

Does anyone remember where I saw an article about plumbing a small shop for air using a small pancake air compressor?  It used copper tubing and short hose connections.  Thearticle must have been 3, 4 or even 5 years ago.  Thanks for any help.

Re: Plumbing for air

Not sure of the article, but do not solder the fittings. Flare the ends and use flare fittings.

The only one I remember was in AWW, but it used air hose for the plumbing....most certainly not what you saw.

Hello Schuttdog and welcome!

 

Not to plug anyone's product but it sounds to me like the Rapidair nylon hose might be a way to go versus copper (cost, ease of installation, etc). Did a quick search and I didn't come up with anything but I'll keep looking.

Re: Plumbing for air

One guy I talked to used 3/8 cpvc pipe. For safety he had several old garden hoses that weren't being used and slid that over the pipe so if the pipe let go the hose would stop flying pieces and being bigger than the pipe and not secured on the ends it would allow the air to have an escape. Maybe not the best way but if you have the material laying around like he did the cost wasn't an issue.

Never do anything you don't want to explain to the EMT.

Re: Plumbing for air

I agree why flared fittings, and why 3/4 copper, wouldn't 1/2 copper be suffice ?

Re: Plumbing for air

I read somewhere that the 1/2 pipe will work but the 3/4 inch gives more stored air for more nailing before the compressure kicks on. I guess like a larger tank. I don't know if it makes that much difference but the author of the artical seemed very convinced about it. He also "zig-zagged" the pipe back and forth up the wall after coming out of the compresser. That way any moisture in the lines will condense in the zig-zag and run back down toward the compressor. He then had a drip leg where the moisture will build up, and at the bottom of the drip leg a valve that he would open to drain out the moisture/water that built up there.

 

I think the artical was in "Fine Woodworking" magazine (if I'm allowed to say that :smileywink:) But I'm not sure. But it was enough to convince me for when I do run a line, I will probably follow his lead.

Re: Plumbing for air

go with the drip leg and forget the zig zag...

 

BTW..

for 1/2 pipe the volume is 1.6 gallons per 100' of pipe as where 3/4 pipe is 2.8 gallons per 100'...

hardly seems worth the effort and expense...



this would have been the week that I'd have finished chewing thru the restraints...
if only new layers hadn't been added....

Stick....
