deaerate

This term is primarily used in technical, industrial, and scientific contexts, such as chemical engineering, metallurgy, and water treatment. It describes a precise physical process of gas removal to ensure material stability or prevent oxidation and corrosion in high-pressure systems.

While "degas" is a more general synonym used across various fields, "deaerate" specifically emphasizes the removal of air. It is a formal, specialized verb and is rarely encountered in casual conversation or non-technical writing.
