What is the standard nozzle pressure for all fog nozzles?

The standard nozzle pressure for all fog nozzles is set at 100 psi. This specific pressure is recommended because it provides a balance between achieving an effective spray pattern and maintaining adequate reach and penetration of the water stream. Fog nozzles use a combination of water and air to create a finely dispersed spray, which can effectively cool the surrounding area and extinguish fires more efficiently.

Selecting 100 psi as the standard nozzle pressure helps to ensure that the nozzle performance remains consistent across different pumping scenarios and that firefighters can operate the equipment without having to adjust for varying conditions in most situations. This consistency aids in training and operational readiness, allowing fire service personnel to rely on standardized practices while ensuring effective fire suppression tactics.
