YouTube video - quite the air system here!!

kcm.MN · Sep 19, 2017

Now THIS is what I call an impressive air setup! Is a little difficult for me to understand the guy - is almost like he's too close to the mic or something. However, the rest of the video more than makes up for that tiny flaw!!

He does have quite a set up! Must have a lot of extra time on his hands! LOL

As for the compressor control switch, I've wired a couple shops so the compressor starter was wired into the shop lights. That way it never gets left on. Just have to learn to expect it to come on when the lights go on!

That is a good compressor! If any of you ever come across a good deal on an old, slow industrial compressor like that, grab it! Those things will last a lifetime!

I'm not quite at the point to try it yet, but I've been thinking about building my own compressor using reinforced 6" PVC pipe and other off-the-shelf items. There would be several pistons powered by an electric motor (radial to reciprocal) and should run oil-free.

...Storm is coming - more later.

Kcm do not use pvc pipe for pressurized air.
At some time in the future it will explode
sending sharp shrapnel in all directions.
Unless you can find some that is air
pressure rated above your expected pressure.
I may not have understood how you were going
to use it. Research deep before proceeding.

When it comes to air lines google Big lock piping systems. Goes together fast and easy. PVC will be damaged by the trace amounts of oil in the pressurized air and grenade at some point.

No oil. VERY slow speed, with all PVC fully encased in fiber-reinforced concrete, which is further reinforced by the steel used as the form. This would be a much larger system than in the video. There will be no tank - it will only be a run-when-needed machine. The PVC isn't for storing pressurized air, but for the initial pressurizing. With this slow a system and these materials, water will be more than adequate for its use, and for this particular need, there's no fear of having water in the air line. Oil might not do any harm, but definitely wouldn't provide any benefit. The water-cooling would only benefit this particular use.

There will also be an HVELP (High Volume Extremely Low Pressure) system which will use a bellows rather than any kind of piston drive.

I don't like things that run fast and generate needless heat, so long as I have the room. ...And I have plenty of room! :wink:

BIG ol' 10-4 on that. I snagged this 12 CFM Quincy off Craigslist for $280. Still a little light-duty for running a blasting cabinet, but handles everything else very nicely.

It is almost like his main project is the compressor. I ran copper out to two filters but nothing like this guy has . I just want to get it done to use the air. He wants to re-engineer air systems. Nice set up he had.

Stephen Newell · Sep 20, 2017

If you do it right there isn't anything wrong with using PVC for compressed air. I've been working around PVC used for compressed air since 1973. Every shop I ever worked at including my own has used it. Like anything it has limits and the pressure rating is posted on the pipe so if you regulate the pressure down below the maximum pressure it won't just explode. Where people get into trouble with it is they run PVC all the way from the compressor to the coupler and when someone yanks on the hose the pipe breaks. If you change from PVC to galvanized at the end of the pipe where you can securely fasten the pipe to the wall before you put a coupler on it you won't break the pipe in that manor. I've seen a pipe broken like that dozens of times and all it does is make noise. I've never seen anyone get so much as a scratch.

Bingo! Thank you Stephen. Just what I had in mind.

markiz41 · Sep 21, 2017

I thought so too. I was always taught that the simpler you make a pneumatic system the more effective it is. Just properly sized compressor, tank and lines. The fewer connections, the better. This guy has so many unions and diaphragms in his system, no wonder he has to shut it off or the tanks leak down.

Seems way more elaborate than necessary. Sound isn't very good because he has a cheap microphone.

I'd run 4 inch steel overhead if I could afford it, with 1 inch drops to regulators. Could easily add an effective 120 gallon of tank capacity in the shop.

I'd also put a small lean-to on the shop to stick the compressor in.

$60.00 on sealed bid company auction. I supplied the motor which I already had. Needed valves lapped and crank seal. it has been running good for almost 6 years now.

Probably should use something like a hose from the compressor to the other tanks. If it was copper (I didn't notice) the copper will work harden from the vibration over time and crack.
