How much pressure in an aerosol can?
What is the PSI of canned air? The maximum pressure for an aerosol can is typically 10 bar (145 psi) at 20 C (68 F). Therefore, a fully compressed air duster will exhaust air about 10 times the can volume.
What happens if you puncture an aerosol can?
Hazards to workers But any number of problems, such as a puncture, a faulty valve, excessive temperatures, or corrosion can result in unintended depressurization. In the most severe cases, aerosol cans may explode, burning nearby workers and showering them with steel shrapnel.

It either ran out of propellant, or the spray tip is clogged. Clogging of the tip normally happens with paint, primer, or anything that gets sticky or coagulated when it dries. Many of these types of spray paints instruct you on the can to turn the can upside down and spray for 5 seconds after you complete your task.
Do aerosol cans lose pressure?
Aerosol cans do loose their pressure over time. But they have to use a new can and install a new pressure fitted top.
Why do spray bottles stop spraying?
The operation of a pump spray bottle depends on a spring-loaded plastic piston operated either by a trigger or a vertical pump mechanism. If your sprayer doesn’t work, it’s either because the nozzle is blocked, the piston seal is damaged or the inner tube isn’t immersed in fluid.
