What is the correct nozzle pressure for a deck mounted or traditional portable master stream fog nozzle?

The correct nozzle pressure for a deck mounted or traditional portable master stream fog nozzle is 100 psi. This pressure is established based on the optimal performance characteristics of fog nozzles, which are designed to produce finely atomized water droplets for effective fire suppression while maintaining good reach and coverage.

Operating at this pressure ensures that the nozzle can deliver a sufficient flow and proper spray pattern to combat various types of fires effectively. A pressure of 100 psi allows for adequate dispersion of water, leading to greater cooling and better exposure of the water to the fire.

It's important to understand that different nozzles are designed for specific pressures, and operating at this recommended PSI optimizes their efficiency. This pressure not only supports the necessary flow rates required for effective firefighting but also enhances the overall safety and maneuverability of the hose team.
