Improved RapidAir Compressed Air System For Home or Garage 

Thanks! Sometimes it's good to be bad 😃

Me too! Nice to know others are living with the same condition I suffer from😂. This video helped me proceed with my system. I have recently rebuilt a Champion compressor and am excited to finish up this long overdue piece of my shop.

dean jordan thanks for watching and glad the information was useful. I have had to replace one HF bowl that started leaking. I think having the ball valves at each regulator and keeping them shut off keeps the pressure off of them and helps them last.

bishop york I used street elbows and some 90's, most of which I had on hand. Street elbows offer more flow due to greater radius where the air makes the 90 degree turn and having a larger i.d. I used a couple of 3/8 brass elbows that fit their ball valve that has a 1/4 hole thru the ball in the valve, the quick connects are also your typical 1/4" size. The 3/8 elbows made the connections easy with fewer joints and were bigger than the 1/4" fittings, so no flow loss. The aluminum blocks will trap water, fill up, and pass it on to devices down stream, they also have more joints which increases the potential for air leaks. Filter regulators remove water and don't pass it on. At about 15psi, these self drain. When I'm not using the system, I shut off the air supply and when/if the air leaks out of the system, everything drains itself. Thanks for watching so closely! Great questions.

Brijesh Jagan had to replace the bowl on one of the 1/2" filters when it started leaking. No other issues and wouldn't do anything different. Thanks for watching!

Great! Thanks so much!!

supervdj all of what you see is standard hardware store stuff. Technically they are "reducer bushings", if I understand which piece you're asking about. Galvanize isn't required, that's all they had when I went to buy the "cross" (4 way) fitting. Thanks for watching!!

Jimmie Gonzalez 1/2. Thanks for watching and good luck with your system. BTW, I saw Tractor Supply has the same system in their brand for less money.

Thanks for the quick reply. I've got only a 1/2 inline filter and a 1/2 filter regulator and 3 3/8 regulators, do you think I will be okay if I Just keep the 1/2 line just as you have hanging off the tank and run the 3/8 coupling from the 4 (Cross) into a 3/8 with another filter?

Jimmie Gonzalez Sounds like you're set up just like my system and it should work just fine!

Just an observation for others to follow your lead - the 4 way and 3 ways that have quick connect couplers also have reducers between them right?

Jimmie Gonzalez that is correct, the cross and tee are 1/2 pipe. The large 3/8" quick connect is bushed down to 3/8 pipe. The 1/4" quick connect is bushed down to 1/4 pipe. And the filter regulators at the point of use, are 3/8 pipe. I kept 3/8 pipe fittings on the inlet side and bushed the outlet side down to 1/4 pipe to fit a standard 1/4" quick connect. The 3/8 ball valves end up having the smallest restriction in the system but the hole through them is about 3/8" so they are still larger than the 1/4 quick connects and the smallest restriction is the hole in the fitting on the air tool.
