    And it’s very reasonably priced. Does the 1/2inch line provide enough air to run your air tools? The outlet on my new 60 gallon compressor is 1/2inch as well.

    Straightening the hose is a task, but not that bad. Very simple and straightforward kit.

    I went with 3/4" sweat copper with drops every 10'. I have a header on one wall and then a crossover to another header on the other wall.

      I am work right now so no pics. If water is problem before you drop go up 2 or 3 inch & then drop water can't go up hill. I am using 1/2 galvanize it makes going up before down easier & cleaner.

        Air gets hot when it is compressed and picks up moisture in the form of vapor. When it cools, the moisture it's carrying drops out of the vapor state and condenses on anything cooler than it is. Consequently, there is no point in having a dedicated water trap anywhere near the outlet of the compressor as the water vapor essentially passes freely through it.

        I found an old post online regarding the use of metal pipe that zig-zags up the wall, peaks at it;s highest point near the 25 foot mark and has at least two downward pointing legs, one at the compressor outlet and one at the end source at least 50 feet down stream of the compressor side of the pipe.

        The metal pipe cools the warm compressed air and the water condenses inside it, runs down from the peak and drops into the down pointing legs at each end where a ball valve can be turned to drain the water.

        On the cool end of the pipes, another branch travels vertically up to a water trap just in case, and then out to the distribution set up you add.

        I have never seen one drop of water in my water trap as 80+ percent of the water drains back towards the compressor=side down pipe and a few remaining drops drain down towards the cool end of the system.

        I used 1/2" galvanized pipe. Copper can work harden and crack relatively easily, even when firmly mounted. Black gas pipe has no corrosion protection. I also use a flexible line to connect the compressor to my cooling pipe.

        What I don't have a picture of here is the pipe slowly zig-zagging up the wal to a single high point, where the moisture can drain back down hill to my two ball valves to be drained. It's amazingly effective at drying the air, inexpensive and easy to implement. My water trap has never had a single drop of water in it, but I used one anyway just because.

          I commonly see the regulator, filter, and water separator built into one unit. And they’re usually mounted very close to the compressor. I guess that would make the water separator part of it very ineffective

            I just have two comments based on 41 years of working in utility power plants. Copper piping is the material of choice for instrument air systems. Corrosion resistance is the primary reason. I worked in plants that were 40 years old at the time that still had the original copper instrument air systems in place. Galvanized was prohibited for instrument air. What happens is that over time the galvanizing would start disintegrating on the pipe interior. The debris would start plugging the instrumentation that the instrument air system fed. Just my view on this.

              Any insight on the plastic coated aluminum used in the rapidair systems as far as reliability? Copper is probably the most commercially used, but it is quite a bit more expensive than the rapidair system. And for my home shop, I don’t think it’ll see the same stress as a commercial shop

              Can't comment on the Rapidair system as I have no personal experience. I know it is quite popular around here. I'd have to count but in our car club I know at least three members have the Rapidair system in their shops and I've heard no complaints about it.

                Sure it has the same stress as a commercial setup. Pressure is pressure. And that's what these lines hold.

                Ordered my compressor, as well as the 100ft 1/2in rapidair master kit. I’ll have to find a couple air hose reels to mount on the ceiling.
