Negative Gauge Pressure

Negative Gauge Pressure is the difference in pressure between any vacuum and atmospheric pressure. The maximum possible negative gauge pressure is always limited by the current ambient atmospheric pressure, which constantly varies, but is typically around 1 bar absolute.

Suction Pressure

Suction pressure is a negative difference in pressure generated between two points which draws a gas or a liquid from a higher to a lower pressure state.

Vacuum

Vacuum is a range of pressures which exist between zero absolute pressure and atmospheric pressure.
