A high pressure air compressor is defined as operating above what pressure?

A high pressure air compressor is generally classified as one that operates at pressures above 1000 psig (pounds per square inch gauge). This definition is important for understanding the operational capabilities and safety measures associated with high pressure systems. Compressors that operate at this level are designed to handle significant stress and require specific components and maintenance practices due to the risks involved in high pressure operation.

Choosing 1000 psig as the threshold aligns with industry standards for categorizing compressors and helps in compliance with safety regulations. It informs the necessary precautions, equipment types, and engineering controls required when working with such compressors in various applications, especially within naval operations where machinists must be aware of the pressures they work with to ensure safety and efficiency.
