Standard Specifications
Glossary of Terms
• Air Consumption
The volume of compressed air, per unit time, required
to operate the vacuum generator; measured in standard
cubic per minute (SCFM).
• Air Supply Pressure
Pressure of the compressed air at the supply inlet of the
vacuum generator; measured in pounds per square
inch (psi).
• Time of Evacuation
The time required to evacuate a given system from
atmospheric pressure to a specified negative pressure
(vacuum level).
• Vacuum
Vacuum exists when atmospheric air is removed from a
system, resulting in less pressure within the system
than the atmospheric pressure outside the system.
• Vacuum Flow
The rate at which atmospheric air moves out of a
system is defined as the vacuum flow rate and is
expressed in standard cubic feet per minute (SCFM).
• Vacuum Level
The level of negative pressure is defined as vacuum
level and expressed in inches of Mercury (in. Hg.).
