What is in canned air?

The usual gases found in canned air are difluoroethane, trifluoroethane, tetrafluoroethane, or butane.

Is compressed air hot or cold?

The ideal gas law tells us when the pressure on any constant volume of gas increases, the temperature also increases. Compressed air is no exception; it can become as hot as 300 degrees F. Without cooling, this level of heat can damage equipment, hurt employees and compromise products.

Is compressed gas hot or cold?

The expanding gas that comes from canned air absorbs heat from the can, making it cold.

Is it okay to breathe compressed air?

Compressed air gets used across a range of industries to provide respiratory protection. It’s used in applications where the risk of breathing ambient air is too high to mitigate using half or full-face respirators. But it is not safe to breathe the compressed air directly following compression.
