Compressed Gas vs. Compressed Air: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 14, 2023
Compressed gas refers to any gas under pressure in a container, while compressed air specifically denotes air stored under pressure.

Key Differences

Compressed gas is a broad term encompassing any gas stored under high pressure, which can include a variety of gases for different uses. While, compressed air, a specific type of compressed gas, is regular atmospheric air that has been compressed.
