Vacuum receivers must be capable of withstanding what gauge vacuum?

Vacuum receivers are designed to operate under a specific range of vacuum pressure to ensure proper functionality and safety within medical gas systems. The measurement of vacuum is commonly expressed in inches of mercury (inHg), and the standard atmospheric pressure at sea level is approximately 29.9 inHg.

When considering the capabilities of vacuum receivers, the requirement is to withstand a full vacuum, which means they should be able to handle pressures approaching absolute zero, equating to a perfect vacuum. Therefore, a vacuum receiver needs to withstand a maximum of 29.9 inHg, which corresponds to the theoretical limit of a complete vacuum (or -29.9 inHg).

This specification reflects the safety and operational standards in medical gas systems, as achieving and maintaining such vacuums is critical for the proper functioning of medical equipment and ensuring that no contaminants can enter the system. Thus, the ability to withstand a vacuum of 29.9 inches of mercury is essential for the reliability and effectiveness of the medical gas systems relying on vacuum receivers.
