Difference between pressure type and gas cylinder fire extin

1. Pressure-storage fire extinguisher is a mixture of fire extinguishing agent and driving gas in the fire extinguisher cylinder.

2. Gas cylinder type fire extinguisher, in which the fire extinguishing agent and driving gas are stored separately in the cylinder of the fire extinguisher, releases pressure gas from the gas storage bottle (both external and built-in), rushes into the fire extinguishing agent storage place and takes out the fire extinguishing agent.

Gas cylinder type fire extinguisher has a separate gas cylinder for storing driving gas, while the driving gas of pressure storage type fire extinguisher is packaged with fire extinguishing agent in the cylinder of the fire extinguisher. There is no separate gas cylinder, but there is a pressure gauge showing the pressure inside the cylinder, which is convenient to check whether the pressure of the fire extinguisher is normal.
