A 1hp centrifugal blower supplies the vacuum and high velocity flow to send the can through 50 ft of 3½ inch tubing from Ed's patio to the crusher in his garage in under one second. A PIC microcontroller operates the whole system from the time he opens the hatch to the time the little chunk of compressed aluminum is ejected from the machine.
