Re: New Compressor arrived today

Well, my opinion is the up down air line design is no bueno and prefer a horizontal top in back and forth design. This means air has to be in the air tank, get trapped at the end by a dryer or go out in the air. That's exactly 2 places to purge water. Each horizontal run in my garage is 20' so I also have room to grow the system.
You need to blow off a little air from the bottom after running the compressor to get rid of condensation in the tank. This is universal.
An up down system means you need to blast those valves out everytime the compressor is used and you're done using it for the day and the air has cooled (or tomorow). I promise some black water will shoot out if you ever forget. Nasty.
Poor design.
For a 2 car garage you don't need a bunch of drops so it makes sense to do as I have and have a manifold at the end with multiple outlets. It's the same argument as above. If you have a horizontal overhead system with vertical drops, you have to purge each drop of water after the air has cooled each time the compressor runs.

Re: New Compressor arrived today

I am open to this...that's why I ask questions...I will have an auto drain on the bottom of the tank...just easy to have it do it for me.

Do you have a picture of your set up?

Re: New Compressor arrived today

No pics. I don't have a pic hosting site account and they're too big to post. You can PM an email address and I can send the dinosaur way tho.
I have a custom (not fancy or expensive) true 3/4" flex line from the tank to the ceiling. That means the ID of the fittings is 3/4". Then 20' pipe with a minimal drop with a union. The same back and forth until I drop into the last horizontal end with another union where I have the filter, dryer, regulator and multiple air outlets. Simple cheap effective.
Auto-drains tend to clog so you have to check; same as manually cracking a ball valve. Barf. I run a L of the bottom of the tank out to the edge, then valve, then reverse back a bit and down. Ok, I'm cheap and lazy.
You just need to crack the valve to drain the water at the bottom of the tank. I used to superstitiously drain the air from the tank but eventually realized that wasn't needed. Sort of like using flare wrenches on bleeder screws. Lol

Pics emailed
BTW, here's a link to SB and apparently my compressor is their bead and butter size. http://www.saylor-beall.com Mine is as shown down to the red tag and stickers, but obviously mine's many years old.

Thanks for the pics Kevin! I might just put an aftercooler on my compressor and be done with it. I also found a used refrigerated air dryer fairly cheap...hmmm

I really liked the SB compressors, but was just out of my price range.

Re: New Compressor arrived today

I am thinking of doing something similar to this (found it at garage journal here)... 50 feet of 3/4" coiled copper. I will feed it at the top...have a T at the bottom with a drip/drain leg then off to the tools and shed out back. The coil will take up much less room than 50+ feet of copper along the walls...and I could mount a fan to blow on the coil if I so desired. Thoughts?

Re: New Compressor arrived today

So I have been debating and researching, even looking for a "cheap" used refrigerated air dryer. Aftercoolers go between the compressor and tank. What is being suggested here is the copper pipe whether it be run vertical with many drains or horizontal with one drain seems to be the consensus. Here is the question I have...instead of running copper pipe on the wall as the cooler...why couldn't I mount a aftercooler (condensor/radiator) after the tank and before my plumbing with a drain? Wouldn't that give the same effect with minimal space taken?
