Badger Range Guard F Nozzle, Pack of 10 - 87-120017-001

The Badger Range Guard F Nozzle (87-120017-001) is a high-capacity, precision-engineered discharge component designed exclusively for the Range Guard wet chemical fire suppression system. In the specialized math of kitchen fire safety, the nozzle is the final point of delivery, transforming a pressurized liquid into a life-saving chemical mist. The F (Fryer) nozzle is a 2-flow point rated component, acting as the industry benchmark for protecting high-hazard appliances like single-vat and split-vat deep-fat fryers.

Featuring a rugged nickel-chrome plated brass body, the 87-120017-001 is designed for rapid field identification via dual-groove identification etched into the nozzle head. This 10-pack fryer series assembly represents the definitive solution for high-volume maintenance and new installations. It is engineered to achieve rapid flame knockdown and initiate a permanent vapor seal, ensuring that a fryer flare-up is suppressed before it can transition into a catastrophic structural fire. Utilizing the genuine OEM 87-120017-001 ensures your facility maintains its UL 300 listing and discharge spray patterns remain consistent with factory-tested safety parameters.

Hydraulic 2-Flow Point Balancing

As a 2-flow nozzle, the F type delivers double the volume of a standard 1-flow nozzle. This higher mass-flow rate is essential for fryers, where the agent must overcome the intense thermal plume of cooking oil above 375°F. The total flow points of all nozzles in the system must not exceed the rated capacity of the agent cylinder to ensure the Karbaloy agent is delivered with enough internal pressure to atomize correctly.

The Saponification Reaction

When the potassium-carbonate-based agent is discharged through the F nozzle, it initiates saponification. The agent reacts with the free fatty acids found in hot cooking grease to form a thick, non-combustible soap foam blanket that excludes atmospheric oxygen to smother the flames and traps flammable vapors to prevent re-flash.

Targeted Misting Dynamics

The internal geometry of the F nozzle is machined to produce a uniform, wide-angle spray pattern optimized for an 18" x 18" coverage area. The nozzle is calibrated to achieve a soft landing of the agent, ensuring maximum chemical concentration on the oil surface without causing dangerous splashing.

Dual-Groove Identification Purity

In a grease-laden environment, reading small part numbers can be nearly impossible. The F nozzle features dual-groove identification, two deep-grooved rings on the body, allowing a technician to verify the 2-flow rating by touch or quick visual scan during a semi-annual audit.

Foil Seal Integrity Defense

The F nozzle is designed to work with specialized foil seals that protect the discharge orifice from caking or solidifying grease. These seals are engineered to rupture instantly at the precise pressure of a system actuation, ensuring an unobstructed flow path.

Corrosion-Resistant Metallurgy

The 87-120017-001 is manufactured from solid brass and finished with a premium nickel-chrome plated brass coating, ensuring the nozzle resists pitting corrosion and maintains the structural integrity of its 3/8" NPT threads for the entire service life of the system.

• Standard 18" Deep-Fat Fryers: Providing total surface protection for single-vat configurations.
• Split-Vat Fryer Batteries: Often requiring two F nozzles to ensure each independent vat receives the necessary chemical concentration.
• High-Efficiency Fryers: Protecting appliances that generate intense radiant heat and utilize large volumes of vegetable-based oils.
• Institutional Kitchens (Hospitals/Stadiums): Maintaining a safe, code-compliant environment in facilities where rapid recovery and suppression speed are essential.
• System Retrofits: The cost-effective 10-pack is the standard inventory item for service companies managing multiple fryer stations.

Precision Aiming Logic

The F nozzle must be aimed according to the specific nozzle aiming chart in the Range Guard Technical Manual. For a standard 18" x 18" fryer, the nozzle is typically centered. Even a 5-degree deviation can result in a dry spot, allowing a fire to bypass the suppression zone.

The 6-Month Visual Audit

During every semi-annual inspection, verify that the foil seal is intact. If a seal is ruptured, the nozzle must be removed and inspected for internal grease accumulation.

Internal Strainer Inspection

The internal strainer protects the orifice from pipe scale or debris. During routine service, verify that the manifold piping has not introduced contaminants that could lead to a partial discharge.

Wrench-Tight Integrity

When installing the 87-120017-001 onto the discharge pipe, ensure the connection is liquid-tight. A leaking nozzle base will bleed off system pressure, potentially failing to achieve the necessary spray pattern.

Can I use the F nozzle for griddle protection?

No. The F nozzle is specifically listed and calibrated for deep-fat fryers. Griddles and ranges require different nozzle types such as the R or G series to achieve the correct coverage pattern for those specific hazard geometries.

Why is this sold in a 10-pack?

For service providers, fryers represent the most common hazard. A single kitchen may have 4 to 6 fryers, each requiring multiple nozzles. The 10-pack ensures that technicians have enough OEM stock to complete a full facility install.

Is the foil seal included?

Foil seals are often sold separately or as part of a recharge kit. However, it is mandatory to use the specific Range Guard foil seals with the 87-120017-001 to ensure proper seal integrity and rupture performance during discharge.
