Half done hooking up compressor in the factory
I have decided that it is not proper to call my business location a
warehouse. The proper name for it is factory, because it was built to house machines that make stuff. That said, I am about half done hooking up the compressor. The compressor is a 10 HP Quincy model 350 compressor, ($200). My home 7.5 HP one will soon be sold. First, it is placed in its intended spot, with carpet under the legs. Second, the outlet for the compressor was not hooked up, and I had to do some digging and thinking to find the wires in one of the breaker panels. That took about an hour to understand. I put a heavy duty 30a disconnect ($5) on the wall and right now, the motor is hooked up directly to the disconnect, for test purposes of course. The compressor seems to run quietly enough to nor be disturbing. Next thing will be putting in a magnetic starter for it (should be easy, once I get the conduit fittings). I have a starter on hand ($40). After this, I need to connect the 175 CFM Pneumatech air dryer ($50) to it. The shop does have compressed air plumbing, although it is somewhat undersized, all pipes are 1/2". But I can live with it. i |

Once you get it running, find the most distant air outlets, and run them until the water stops flowing. Them move towards the compressor, repeating with the other outlets. Finally, check back at the end to make sure that none snuck by while you were draining the other outlets. Remember -- just because *you* are installing an air dryer, there is no certainty that the previous owners did. You may be lucky, and find out that they did. I remember when I used to work for a certain company in this area, if you started to use an air drop which had just been hanging there for a while, you had to expect to get a lot of water out of it before you got any air.

If you end up in that situation, it can be fixed. All you have to rework is the main trunk line larger, say a 1", and then when you reconnect all the intermediate tap points you make the tees off the mainline go UP off for 6" or so, then they go horizontal out to the individual outlets. And they have a drip leg at the bottom with a butterfly valve at the bottom. You can rework the original 1/2" pipe that way too, if you never plan on using more than one drop at a time. But you'd need to put all the big draws like bead blast cabinets Right Next To the compressor. Do the three ball valves (In - Bypass - Out) between the compressor outlet, the Air Dryer, and the mainline - so you can cut it out of the loop quick and easy if something goes wrong. And when you get to the far end of the Mainline - that has conveniently sloped downwards somewhere between 1/16" and 1/8" a foot or so from the high end at the compressor and air drier toward that point, you put a drip-leg and a drain valve there too. And you don't put Any plain couplings At All in the new Black Steel Pipe mainline - they're all Tees with the unused spigot pointing up and plugged. That way you don't have to take the whole thing apart again if you want to add a drop. Threaded Pipe is always a pain in the arse that way. Me, I'd use Brazed Copper all the way - you want to add a tee, it's not an issue. Cut and braze when and where needed. And make the taps go UP the same way, so any water that condenses out gets left behind. -- Bruce -- |

Galv flakes a lot. I hope you use a FLR on each drop, with or without lube. F'rinstance http://goo.gl/2yi3z . Indeed. Ive made a point to NEVER use Galvanized pipe in any of the 100 or so air systems Ive designed and installed. This after repeatedly having to unchoke or replace air solenoids that were filled/blocked/ruined by flakes..sometimes BIG flakes of Galv. Black pipe is cheaper, and while it may rust a bit more internally..it reaches a point where little comes out of it..and when it does..is dust that passes through such devices nicely. Particularly when one does moisture control before the air reaches the plumbing. Copper is best..but as Larry indicated...figure out which kid you like the least, then sell him/her for the bucks to install it. When a joint of 3/4 black, 20 feet long is $11 or less...its the most viable candidate for most folks.

Good point. I will do that. There is a lot of plumbing work to be done, hooking up compressor to the dryer, dryer to the compressed air system, etc. i |

Weird how there was a machine shop out in the middle of just cornfields, but that was the reagan era for you, the defense buildup was so large there was (I have to assume by the existence of this setup) an actual lack of machining capacity.
