A little tip for when applying PTFE tape, turn the reel around the other way when wrapping it around the fitting. That way you don’t constantly have excess.

Beautiful work & lots of copper & soldering work! However, the most efficient heat exchanger is a tube & fin aftercooler like a Derale #15300 or even a new or used automotive A/C condenser. The surface area for heat exchange in the tube & fin design is mind boggling compared to the tube surface area. Duct & seal a fan to blow or suck thru the fins & it's unbeatable! The most efficient way possible is to pipe the hot air directly from the compressor pump outlet into the tube & fin, fan cooled "aftercooler", then into a water seperator, then into a tank. No more water in your tank! The best hobby sized system I've ever seen was designed & built by an engineer (KZfaq) Doug Kronemeyer, a 3 part video set (DIY#9) chocked full of engineering logic & knowledge! His system is so good it rivals the performance of a hi dollar refrigerated air drier! And it is a passive system except for the fans! Give it a look, you will be impressed! Also a shout out to Bud Stiner, THE Compressor Guru (KZfaq) for DIY compressor knowledge, parts & service! Paul from S. Central Tx.

Excellent job! I will build one of these too! Very inspirational, thank you!

Good stuff! That’s a nice setup. Thanks for sharing!

Great job 👍

Very nice!!

Wow richtig geil gemacht Daumen hoch da lasse ❤️⭐👍

Great setup, and well executed. Although you now need to make the drainage system from the water traps :D. I’m only joking, good job!

Very educative video! Can you tell me what the purpose of all the loops are and why you have three valves at the bottom?

where did you find those 90 degree bends? all the ones I see at HD are the short 90's not the longer sweep ones like you have?

How are the two compressors connected? Didnt you need NRVs?

Very well done sir. If you don't mind, how much money do you have tied up in that copper system? Thumbs up on your video bud. 👍

So where does output of small tank go to?

also what kind of flux are you using?

Wouldn't it be better to have the air dryer before the tank so that you keep the inside of the tank dry, so that you get no rust in the tank.

Really nice. What’s the length of your long pipes.

How thick is the pipe for the watertrap ?

I keep seeing this copper pipe and all those $150 double dryer things... think yall waste $ ....I work on large yachts, the painter has it down with a simple solution.....if your pushing 150 lbs just use 100 to 150 ft of 1" PVC (sch40 good to 270 lbs, if above 75 degrees might go to 215 bursts at 1450) and use a Motor Guard filter. even better the filters are cheap, sounds weird but just use a roll of toilet paper and rip off about 20 layers and use that in the filter..... Think about this....the guys been doing this for well over 30 years, using high end ( AwlGrip) paint spraying 1 or 2 million dollar yachts no problems !!! the filter case is $80 on Amazon, 1" PVC is less than by an easy 80%... you can use 3/4" pvc just ran a little more. has a just less than 10% more pressure and burst factor. My opinion is just too much hype over this whole thing, the yacht paint is no fool and a smart man and well quality is his key to success.
