Vacuum pump capabilities vs altitude.

Postby emsvitil » Tue Aug 09, 2016 2:51 am

Say you have a single stage vacuum pump that can goto 100 microns at sea level.

If you goto 18,000 ft, where the air pressure is roughly half that at sea level; can you get down to 50 microns with the same pump?


The exhaust is only working against half the air pressure, so wouldn't the micron level also drop by half?
