Precision Vacuum Pumps are causing a quiet revolution! Not too many people appreciate the irritating clatter and rapping noise commonly associated with vacuum pumps. That's one of the big reasons why Precision pumps enjoy such wide acceptance today, just a little more than a year since their introduction. Virtually noiseless and vibrationless, they offer an advantage that is welcome in any environment. And they do a better pumping job! Compare published performance curves and you'll find Precision pumps are more efficient at actual working pressures — up to a remarkable 79% at one micron. Guaranteed ultimate vacuum runs to 0.1 micron of mercury — 1 x 1 0 4 Torr.
