In a vacuum system, what occurs when not enough vacuum is maintained?

When a vacuum system fails to maintain adequate vacuum levels, the primary consequence is the entry of air into the system. This air intrusion can compromise the efficiency and functionality of the vacuum. In medical gas systems, maintaining a proper vacuum is crucial for preventing contamination and ensuring optimal performance of the equipment.

The failure to sustain sufficient vacuum can lead to various problems, including the potential for contaminants to enter, which may affect the safety and effectiveness of the medical gases being used. Additionally, such air entry can disrupt the intended functions of the system, possibly leading to other issues down the line, such as malfunctioning equipment or inefficient operation, but the immediate concern is air entry.
