What pressure is typically used for a fog nozzle?

The typical pressure used for a fog nozzle is 100 psi. This pressure range is standardized for the effective operation of fog nozzles, allowing for optimal performance in fire suppression. The 100 psi setting is designed to provide a fine spray of water that helps in cooling and displacing heat while effectively combating fires. It creates a mist that enhances water's surface area, improving its absorbency and cooling capacity.

This consistent pressure is important for ensuring the nozzle produces the desired foam or water droplet size, which is critical in controlling the spread of fire and reducing the ambient temperature in a firefighting scenario. While other pressures can be used in specific situations, 100 psi is widely recognized as the optimal choice for general firefighting operations involving fog nozzles.
