lowervacuum

lowervacuum is a term sometimes used to describe a vacuum pressure that is not exceptionally high. In practical terms, it refers to a vacuum that is significantly lower than atmospheric pressure but may not reach the ultra-high vacuum (UHV) levels achieved in specialized scientific or industrial applications. The specific definition of "lowervacuum" can vary depending on the context and the equipment being used.

In many general applications, such as vacuum sealing for food or basic laboratory aspiration, a "lowervacuum" might still be considered a good vacuum. For example, a vacuum cleaner operates at a very low vacuum compared to atmospheric pressure, but it is not considered a "high vacuum" in scientific terms. Similarly, some industrial processes that require a reduced pressure environment, but not an extreme one, might be categorized as operating under lowervacuum conditions.

The achievable pressure in a lowervacuum system is typically determined by the pump's capability and the system's leak tightness. Compared to rough vacuum (which is closer to atmospheric pressure) or high vacuum, lowervacuum occupies a middle ground. It is a level of reduced pressure sufficient for many common tasks without requiring the sophisticated and costly equipment needed for ultra-high vacuum.
