A standard gauge pressure of 160-185 psi applies to which of the following?

The standard gauge pressure of 160-185 psi is applicable to instrument air. Instrument air refers specifically to the compressed air that is used in industrial plants to provide power for tools, instrumentation, and actuation of devices. This range of pressure ensures that the air is delivered reliably and effectively for control systems and pneumatic devices.

In medical gas systems, maintaining specific pressures for different applications is crucial for safety and functionality. Instrument air ensures that the pneumatic components operate effectively, and the pressure range specified allows for the necessary force to drive instruments without risking damage to sensitive equipment.

The other options do not align with this pressure range, as each serves different functions with distinct pressure requirements. For instance, laboratory air typically requires lower pressures, while laboratory vacuums operate below atmospheric pressure, and non-medical air does not have a standardized pressure range aligned with medical or instrumentation needs. Understanding the specifications and purposes of each type of air or vacuum is important for ensuring proper installation and operation in various applications.
