Would it not achieve the same purpose by using high pressure air to clear small debris from electronics? Is there some reason this is impossible? Also what benefits does air duster gain performance-wise by using such a dangerous chemical?
In: Engineering
In order to create a notable amount of compressed air, you really want to be able to store the contents at a high enough pressure that it condenses to a liquid. A small amount of liquid can become a very large volume when given room to expand.
At room temperature, an equilibrium between liquid and gaseous oxygen is very difficult to maintain, typically requiring a vaccum insulated container and a pressure relief value to ensure the contents don’t reach too high of a pressure/temperature.
Refrigerants are much easier to store, as the transition from a liquid to a gas at room temperature occurs moderately close to atmospheric conditions.
