Quiet operation with noise level at or below 54 dB(A)
Overheat protection for safety
Start pumping at a lower pressure in the second stage to draw a deeper ultimate vacuum
The displacement at 60 Hz is 0.6 cfm, while is 0.5 cfm at 50 Hz
The ultimate vacuum is 0.15 Torr when full gas ballast is reached, and the ultimate vacuum is 0.0023 Torr when there is no gas ballast
