More Flow Without Losing the Line
Select your options to build the correct nozzle configuration
The Working Fire™ is a fixed-orifice combination nozzle designed for departments that want dependable everyday flow with the ability to push more water when the fire demands it. Under normal conditions, it operates like a fixed-flow nozzle at either 150 GPM at 75 PSI or 160 GPM at 50 PSI, depending on the model. When the nozzle is over pumped beyond its rated flow, the built-in pressure relief feature helps limit nozzle reaction, so the line remains more manageable for the crew.
The Working Fire operates like a fixed-orifice combination nozzle up to its rated flow and pressure. Crews get predictable performance, familiar nozzle operation, and straightforward pump calculations for initial attack.
When flow increases above the rated 150 GPM or 160 GPM setting, the pressure relief function helps reduce the sharp rise in nozzle reaction normally seen with standard fixed-flow nozzles. This allows crews to flow more water while keeping the attack line more manageable.
The Working Fire is available in two primary performance options:
150 GPM at 75 PSI
160 GPM at 50 PSI
This gives departments the choice between a traditional mid-pressure attack line setup or a lower-pressure option designed to reduce nozzle reaction and improve line handling.
The Working Fire gives crews predictable fixed-flow performance for the first line through the door, with enough flexibility to push more water when conditions worsen.
When the incident calls for more GPM, the pressure relief feature helps crews increase flow without the same reaction force spike expected from a traditional fixed-flow nozzle.
The 160 GPM at 50 PSI model supports departments looking for lower nozzle pressure, reduced reaction, and easier line advancement while still meeting strong attack-line flow targets.
For crews operating with limited staffing, nozzle reaction matters. The Working Fire is designed to keep the line more manageable as flow increases above the rated setting.
The Working Fire is a fixed-orifice combination nozzle with a built-in pressure relief function. It operates like a standard fixed-flow nozzle up to its rated flow and pressure, then uses pressure relief to help manage nozzle reaction above that range.
A standard fixed-flow nozzle can see a major increase in nozzle reaction when over pumped. The Working Fire includes a pressure relief feature that helps limit reaction force as flow increases above the rated setting.
The pressure relief feature activates when flow exceeds the nozzle’s rated flow, either above 150 GPM or 160 GPM, depending on the model.
Yes. The 160 GPM at 50 PSI model is designed for departments that want lower nozzle pressure while still maintaining a strong attack-line flow.
