Wow !!!!!! I just checked out that "Rapid air system.
What a rip-off.
Over $800 to do just a 3 bay shop
My shop is over 3000 sq ft, ran all the air lines in 1 " copper,outlets
every 10 ft all around, plus plumbed 2- 80 gal compressord and the spray booth and only spent around $300 in pipe, fittings ,drains etc.
Less than 8 hrs and it was done ( over 250 soldered joints)
