Sandblasting is much more effective with 16 cfm than 10 at 90 psi... now my sand blaster will show 75 psi when it used to show 40!

And this is with a 4" pulley when we should be using a 5".. it can only get better!

I still want to find a way to use both pumps at once tho /forums/images/icons/laugh.gif but we dont have two sets of 240v lines in the garage... darn /forums/images/icons/frown.gif But then again... theres always gas engines /forums/images/icons/smile.gif

As long as the running amps of both units are below the rated capacity of the circuit (reading the circuit breaker can tell you this), you could run both compressors off of one circuit, as long as you started them seperately. Compressors are hard to start, even with a pressure dump, and approach the locked rotor amp rating of the motor, which, if both would start at the same time, would likely trip the breaker (I'm thinking 40 amp)

Happy blasting!
