Let's be sure to keep things straight, as Rob is doing. The electric pump
in the original post will draw down to 75 microns, which is 29.917 inches
of mercury at sea level. I call that a hard vacuum. It won't survive a
shop's duty cycle, perhaps, but it will work for us if we let it run long
enough. I'll bet shops don't pull a harder vacuum, tough a shop-grade pump
might get there faster.
The air-pressure-operated venturi pump that Tyler posted is the one Matt
(and Rob) warned against. It does not pull a hard enough vacuum to dry an
AC system.
