Definition and Basics

This concept refers to a device or system designed to distribute a controlled amount of negative pressure to various points or areas as needed. The fundamental principle behind this technology is the creation of a vacuum or a pressure that is lower than the atmospheric pressure. This is achieved through the use of pumps or venturi systems that remove air from a sealed environment, thereby reducing the pressure within that space. The ability to control and distribute this negative pressure is crucial for various applications where maintaining a specific, lower-than-atmospheric pressure is necessary for operational success.

History and Development

The development of negative pressure technologies has evolved over time with advancements in materials and control systems. Initially, simple mechanical systems were used to create and manage negative pressure. However, with the advent of more sophisticated control systems and sensors, the precision and reliability of these devices have significantly improved. The evolution of these systems has been driven by the need for more accurate control of pressure in a variety of settings, leading to the integration of digital technologies and feedback mechanisms that ensure consistent performance.
