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. (evacuation speed) Product options Standard (NVP20) Pneumatic blow-off (NVP2X) Valve controlled blow-off (NVP20V) Multi-port (NVP20M) Air Saver (NVP20C) Fluid: Filtered (100 Micron) unlubricated, non-corrosive dry gases Operating Temperature -30° to ~250° F (-34° to ~121°C) Operating Pressure 80 PSI (5.5 bar) Standard or 60 PSI (4.1 bar) Materials Generator Body: Anodized Aluminum Supply/Vacuum Line 1/4" OD for sizes 60 and 90 3/8" OD for sizes 100 and 150 Mounting Holes Mounting holes accept 10-32 [M5] screws Performance Level Designations "M", "Y" 0-20"Hg [0 to 677mbar] for medium vacuum/high flow applications "H", "Z" 0-28"Hg [0 to 948mbar] for high vacuum/standard flow applications
