75 M O D U L A R VAC U U M G E N E R ATO R S 1 For more information or for additional configurations, please contact us at NASInsideSales@imi-precision.com » Energy efficient – compressed air on only when needed, automatic shut-off » High Productivity – non-clogging design reduces downtime » Strong hold – powerful vacuum up to 28"Hg [948mbar] » Mounts Easily – compact and lightweight » Fast Response – installs close to vacuum point » Efficient – minimal air consumption » Reliable operation – straight-through design with no moving parts Generator Selection 1. Determine the desired evacuation time (speed) 2. Calculate the total volume of air to be evacuated in the system including vacuum lines, vessel/ cavity size, cups, etc. 3. Determine the desired vacuum level, "Hg/mbar Application ex.: Evacuate 2 cu.ft. of air in 1 minute (60 sec) at a vacuum level of 21"Hg Formula: Time (60 sec)/Cu. ft (2) = 30 seconds per cu.ft.
