Common Questions

Q: How does the adjustable flow rate benefit different applications?

A: The dual-range 20-60 GPM flow adjustment provides flexibility for different operational needs.

20 GPM (Lower Flow Rate):

• Conserves water while maintaining effective coverage.
• Ideal for misting, controlled soaking, or sensitive areas where excessive force could cause damage.
• Useful in wildland firefighting for indirect attack methods, such as pre-wetting fuels or maintaining fire breaks.
• Reduces water demand when supply is limited, such as in rural or remote settings.

60 GPM (Higher Flow Rate):

• Delivers a high-volume stream for maximum impact.
• Effective for fire suppression, structure protection, or rapid coverage of large areas.
• Suitable for knocking down flames quickly when high water output is required.
• Enhances cooling and steam conversion in fire attack scenarios, improving overall efficiency.

Adjusting between these settings ensures optimal water management, balancing force and conservation based on the operational demands.

Q: Is this nozzle suitable for firefighting purposes?
A: Yes, the adjustable flow rates and durable construction make it suitable for firefighting and other demanding applications.​

Q: Can this nozzle be used with hoses that have NH (National Hose) threads?
A: No, this nozzle is designed specifically for NPSH threads. Using it with NH-threaded hoses may require appropriate adapters to ensure compatibility.​
