SW Ohio
x2 on pressure vs vacuum 14 psi vs 50+
I once saw on a job site guys pushing a foam ball tied to string about 700' through what looked like 6" conduit, pulled a larger rope with the string and then a honking big wire with the rope using a winch at first and then a bobcat to pull the rope! Using air it only took a couple minutes to get the ball to the other end, couldn't feed the string out fast enough!
