Plumbing for shop air?

So it's just inline with the outlet of the cooler?

I am looking at doing the setup that uses a stand pipe off the outlet of the cooler so as the cooled air drops the water out it will go straight into the stand pipe and a float drain.

Something like this but with a auto drain float valve on the bottom.
(This doesn't seem to be a great installation, just has the right idea)

Pretty much. I come out of the bottom of the cooler and straight into the separator, then out of the separator and into the tank. I used soft copper and compression fittings everywhere (good compression fittings from McMaster...the shit from Amazon that I started with wouldn't seal for shit and a couple blew apart). I tried soldering in one joint (hot side) but it also blew apart...I just used plumbing solder, maybe it got hot enough to melt the solder?
 
My only issue with that is, why heat up the air that’s supposed to cool the compressor?

A ton of compressors come just like that with intercoolers. I've never paid attention to if they suck or blow across the compressor head. I doubt that generate that much extra heat that it would affect the compressor either way.


I used to hav one of these but IRs that was set up like that. I have the intercooler for my Emglo but the frame was all mangled when I got it and I never got around to repairing it. Really should get on that too.

Yeah I was going to braze the lines with refrigeration solder and refrigeration copper (type L maybe?)
 
It's like having your AC condenser in front of the radiator... Doesn't really matter.

Probably not. I’m using a Hayden 1299, it’s too big to mount in front of my pulley anyway.

I understand the factory after coolers are mounted there but, they are built to a price point!
My 7.5 hp slow speed compressor is rated for 15 hp. If I ever wanted to double the CFM the cooler would still huge AND, I only spent half of what the factory option would have cost!

I never get any water coming out of my lines with this setup. This setup plus the refrigerated air dryer makes for air dry enough to paint without a single fisheye or other defect caused by dirty air. It works really well, and lives outside.

Rarely ever have water in the tank, but I do still get some water in the tank, just not much. Not like before.
 
One of my ag customers just built a 60x60 shop and i talked them into using the 1" aluminum tubing rapid air system and it turned out very nice. Another customer used the 1/2" plastic rapid air and they didn't try to straighten the tubing and it looks like shit. I also had the first customer add 120v wiring for a auto drain on their compressor but they never installed one 🤦‍♂️.

It's now packed with so much shit you can hardly walk thru it. Damn farmers.

I have one of these if you want more info

Got a pic of the cooler and plumbing?

With no water seperator between the outlet and the tank that probably only allows more air volume (cooler) in the tank, not really water removal.

I had two that I picked up a couple years ago and resold. You can pretty much see it all in that pic. Just a big serpentine coil between the pump and tank. No water collection between them, so it likely just drops a lot more water in the tank vs. not having it. I have pretty much the same setup that came on my Emglo, I just need to build a new mounting frame for the coil and I'll probably incorporate a separator after it as well.

I still have this refrigerated drier that I got with the same lot. It shows and error code when I power it up. I always figured it was just because it didn't have any pressure on....I should really plumb it up and see if I can get it to work. :shaking:

That's crazy that giant aftercooler doesn't have a drain before it dumps all the water into the tank?
Maybe they can't sell new air compressors cause the tanks rot out if they separate the water ?

Yeah definitely power that thing up and see what's going on.
I had planned on getting a HF refrigerated dryer when I planned building the plasma table, but now I'm not sure if that's needed for hobby bracket making. A annual motor guard filter and some added compressor cooling/water separation might be just as good.

They all came out of a discount tire and all 3 had auto drains on the tanks so they didn't hold water for very long. I don't think it's common for compressors that come with integrated coolers like those to have a separate drain before the tank.



The blue Horizontal is my Emblo that I'm still using. I have pallet racking along that wall now and the compressor sitting under it. I'm half tempted to stick the whole thing up on the top shelf of the racking. Or, make a new mounting plate for the motor and compressor and stick the tank outside behind that wall. Or maybe scrap the tank, put the motor and pump up high and plumb it in to the drier and use use the drier's tank as my main tank.

Floor space is a premium but I keep balking at moving mine outside.
I think that makes for a really hard life on a compressor it harsh climates.
An elevated platform in the corner of my shop though wouldn't take up any room.
 
If anyone is looking for an idea on a catch can for water. Basically a 3 inch pipe with caps welded in the end and tapped for fittings. Then threaded bungs welded on for inlet and outlet
