Can you explain this setup? Basic use and precautions? It was in my garage and I want to learn to use it.

Nothing wrong with that PVC pipe in that application. Keep using it.
Just because the first reply has a avatar that is a photo of big machine does not mean that person is correct. |

Black pipe and galvanized pipe rust, become brittle and corrode with age causing shrapnel when it explodes.

PVC pipe isn't for air.
Use black pipe, pex, or air specific line. PVC is a shrapnel thing with air. |

Pipe or copper I used this blue not sure what its made of line.
Cheaper and faster set up but always getting small leaks. Wish I would have used black pipe. I have a water filter and trap at compressor and at my cleaning tank area I put another water trap and pressure regulator. |

Technically, the PVC should handle the pressure, but most people would not use it for compressed air.
The first cannister is the water separator and it should separate out the condensation from the compressed air. It needs to be drained periodically. The second unit with the gauge is your pressure regulator and is used to set the pressure you wan to run your tools at. The third cannister is the oiler. It should be filled with air tool oil and adjusted to supply a very fine mist of oil to lubricate your tools. |

Whole bunch of idiocy in this thread.
Plenty of steel pipe out there for air. It’s very reliable and doesn’t explode when it fails. PVC on the other hand is no good for air. It ages poorly, especially in a shop filled with solvents and ozone from welders and motors. It gets brittle and when it fails generates lots of shrapnel. |

Quote HistoryQuoted: Black pipe and galvanized pipe rust, become brittle and corrode with age causing shrapnel when it explodes. Black pipe just gets pin holes when it rusts. No shrapnel... Tap that PVC a little too hard with a project you are trying to maneuver in the shop and you better be wearing your eye protection... |

Since no one is answering your question....
The cylinder on the left is a water separator. It will remove a good portion of the water in your compressed air. (The water is from air humidity) You should drain it regularly via the valve on the very bottom. I drain mine each morning when I'm planning a full day in the garage, or before I paint anything, or whenever I see there is water accumulating in the bowl. You should also drain the tank drain on your compressor regularly. Some people drain both of these at the end of every use. It's up to you. The middle part is your pressure regulator. The knob on the bottom is turned to raise or lower the working pressure. For the majority of the time you will leave it set the same as your compressor's pressure and use tools at full pressure. You will want to lower it if you paint with a paint gun. The right cylinder is the oiler. I don't use one since I paint a lot. If you use a lot of air tools such as impact wrenches, ratchets, or grinders you will like to keep it filled with an appropriate tool oil. You do not want oil in your line for sandblasting or painting. Since I do a lot of both, I manually oil each tool with an oil can. My preferred oil is Marvel Mystery Oil, but there are plenty of opinions about tool oil. You will want to turn the air pressure off at the compressor before opening this to fill the reservoir, but that's a little obvious. |

I have air tools I've used professionally for over 40 years still running.
I oiled them when I would think of it with what ever I had on hand. Would never put an oiler in line. How would you blow off parts or paint. |

Guess who repiped it? PVC and compressed air, are an accident waiting to happen. |

Replace the oiler with a second water filter..oil your tools after each use..that way they sit with fresh oil inside the internals which does far more for protecting them than a crappy inline oiler that rarely works right..Plus oil is the death of paint work and any oil in the hoses will constantly be coming out on your work area...I would not use plastic pipe..use black pipe and be sure to put a water trap on each termination point..also make sure you drain the tank daily....Also make sure you kill the power anytime you leave..I have seen shops burnt to the ground when a hose popped and the compressor ran until it caught on fire and burnt the place down...

OP, you can buy Air Tool Oil pretty much anywhere, ditch the inline so you're not limiting your options (paint, sandblasting, dusting stuff off, etc).
And I agree that PVC would make me nervous!! |

Awesome help guys. Going to swap the PVC out with black pipe, pull the inline oilers, and put in a water separator at all termination points. I also have this, but found a manual on line for it.

Air tools rock. Schedule 40 PVC...what pressure are you maxing at? I have 25 year old schedule 80 PVC all through my shop, several hundred feet of it and never had any of it "blow up". There have been times when a line got broke but it was easily repaired. Now, as a business I always planned on and wanted to swap it out and finally got about 99% complete with all new lines in copper.
What you need to be concerned about with air lines is proper sizing to prevent pressure drop and distance from compressor to water separator. |
