Buckeye N-2W White Nozzle, 10 Pack

The Buckeye White Nozzle (N-2W) is the high-capacity solution for wide-reach hazard suppression and extra-low proximity configurations. While standard nozzles manage focused point-source hazards, the 2-flow wide-angle design projects an expansive high-dispersion mist. This specific dispersion pattern makes the N-2W the primary specified choice for large-scale ventilation defense in industrial exhaust ducts with up to a 150-inch duct perimeter (381 cm) and specialized culinary setups where the mounting height is extremely restricted to 2 to 10 inches (5 to 25 cm).

Constructed from chrome-plated brass to withstand high-velocity exhaust plenums, the N-2W is instantly identifiable by its distinctive white color-coded band. This visual cue ensures safety hardware contractors can verify at a glance that the system's hydraulic math supports the wider coverage area. By delivering double the agent volume of a standard tip, the N-2W achieves a rapid saponification reaction across expansive surfaces, ensuring total fire suppression in areas where a narrower spray pattern would leave dangerous dry spots. The N-2W-10 10-pack provides the inventory needed for comprehensive ventilation protection.

The N-2W must be installed by a licensed fire suppression technician in strict accordance with the Buckeye Kitchen Mister BFR design manual, NFPA 17A, and NFPA 96. The mounting height of 2 to 10 inches must be observed precisely. At standard heights of 30 inches or more, the wide-angle spray pattern becomes too dispersed, potentially failing to reach the necessary chemical density required for rapid flame knockdown. For duct applications, the duct perimeter at the nozzle location must not exceed 150 inches (381 cm).

Because the N-2W is often positioned in grease-trap zones where caking is most severe, a fresh Buckeye blow-off cap must be installed and verified at every 6-month inspection. The wide-angle orifice geometry is particularly vulnerable to blockage from solidified grease; any obstruction will disrupt the dispersion pattern and compromise suppression. Because the N-2W consumes 2 flow points from the cylinder's total pressure budget, the technician must also verify during system design that the sum of all nozzle flow points in the system does not exceed the rated cylinder capacity.

Why is a 2-flow rating necessary for a 150-inch duct?

In large-scale ventilation, grease accumulation covers a massive surface area. The N-2W provides the necessary chemical mass-flow rate to coat the entire perimeter of a 150-inch duct instantly, ensuring the agent is not diverted by high-velocity exhaust air before it can achieve a vapor seal.

Can the N-2W be used for standard high-proximity ranges?

Generally, no. The N-2W is specifically calibrated for low-proximity and extra-low proximity applications. If mounted at standard heights of 30 inches or more, the wide-angle spray pattern would be too dispersed, potentially failing to reach the necessary chemical density required for rapid flame knockdown.

Does the wide-angle orifice geometry require different maintenance?

Because the N-2W is often positioned in grease-trap zones, it is highly susceptible to grease caking. Technicians must verify that the wide-angle orifice geometry is protected by a fresh Buckeye blow-off cap during every 6-month inspection to ensure a consistent discharge pattern.
