Buckeye N-1LP Red Nozzle, 10 Pack

The Buckeye Red Nozzle (N-1LP) is a precision-calibrated low-proximity nozzle specifically engineered for the confined zones of a Buckeye Kitchen Mister BFR fire suppression system. While the Blue (N-1HP) series is optimized for high-proximity surface protection, the N-1LP Red Nozzle is the definitive solution for exhaust duct fire protection, plenums, and low-clearance appliance safety. As a 1-flow point rated component, it atomizes the wet chemical agent into a high-velocity misting pattern designed to achieve rapid knockdown in high-airflow environments.

Constructed from chrome-plated brass to resist the corrosive effects of aerosolized grease, the N-1LP is easily identified by its distinctive red color-coding. This visual identification ensures safety contractors can verify the hydraulic calibration protecting the ventilation infrastructure at a glance. When mounted at a 30 to 40-inch mounting height or positioned within a duct with up to a 50-inch duct perimeter (127 cm), the N-1LP provides the targeted chemical concentration required to satisfy UL 300 and NFPA 17A mandates. The N-1LP-10 10-pack ensures consistent inventory for full-hood retrofits.

The N-1LP 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 30 to 40 inches must be observed precisely; installing outside this range can result in poor agent distribution and a failed UL 300 fire test. For duct applications, the duct perimeter at the nozzle location must not exceed 50 inches (127 cm) to ensure the agent achieves full coverage of the grease-laden interior walls.

A blow-off cap or foil seal must be installed on every N-1LP at all times. Given the nozzle's frequent placement inside ducts where grease caking is most severe, the cap is the only way to ensure the 1-flow hydraulic pressure is unobstructed during actuation. During each semi-annual inspection, technicians must verify the cap is present and intact, and that the nozzle orifice is free of blockage. Any nozzle showing signs of corrosion, orifice restriction, or heat distortion must be replaced with a new OEM N-1LP to maintain the system's UL listing.

Why is the N-1LP specifically required for ducts?

Exhaust ducts present a unique fire hazard because they channel flames and high-velocity air. The N-1LP is engineered with a specific orifice geometry that maintains misting integrity even in the presence of strong exhaust suction, ensuring the agent is not pulled away before it can coat the grease-laden duct walls.

Does the "Low Proximity" rating affect the nozzle's mounting height?

Yes. While high-proximity nozzles are designed for distances up to 48 inches, the N-1LP is optimized for a 30 to 40-inch mounting height over specific appliances. Installing it outside this range can result in poor agent distribution and a failed UL 300 fire test.

Can I use the Red Nozzle with standard blow-off caps?

The N-1LP is fully compatible with Buckeye's line of blow-off caps and foil seals. Given its frequent placement inside ducts where grease caking is most severe, maintaining a fresh cap is the only way to ensure the 1-flow hydraulic pressure is not obstructed during actuation.
