Michael Kellough said:Kevin D. said:They both are fairly quiet and similar in sound level to the ear. The difference is in the sound itself. The JC10 has a more bass like sound to it whereas the Cadex has a more prrrrt sound to it. Neither is annoying or seem loudish, they just sound a little different from one another.
The big difference between the two is recharge time. The JC10 takes a full minute to charge from empty, whereas the Cadex 4 takes 15 seconds. I think this is a combo of factors. The JC10 has a somewhat larger tank capicity, but the RPMs of the motor pump on the Cadex runs at twice as fast of the RPMs of the Rolair.
I'm going a bit from my memory from a few months ago when I was evaluating all this, but IIRC the Cadex is 3.8 at 90 psi whereas the Rolair is 2.3 @ 90.
Are the cut-in cut-out preassures the same?
Don't know. I'll try to remember to look it up.
