A fire extinguisher is primarily considered pneumatic, as it uses compressed gas to propel the extinguishing agent out of the nozzle. The pressure inside the extinguisher is created by gas, which can be either stored under pressure or generated through a chemical reaction. While hydraulic systems also use fluids under pressure, fire extinguishers do not rely on liquid pressure to discharge the extinguishing agent.
