Badger High Overhead Nozzle - 83-259270-000
The Badger 83-259270-000 (also referenced as 259270) is a precision dry chemical nozzle engineered for high-overhead area protection in industrial environments. Where low-overhead nozzles are optimized for proximity, the 83-259270-000 is designed for the long throw -- delivering sufficient kinetic energy to propel dry chemical agent from ceiling height to the hazard below without being dissipated by building ventilation. It is the standard nozzle for Industry Guard systems protecting large-scale manufacturing zones, spray booths, and similar applications.
Constructed from nickel-chrome plated brass, the 83-259270-000 resists the corrosive vapors and particulate buildup common in industrial settings. Its internal strainer manages laminar flow to produce a cohesive solid cone pattern, ensuring the center of the hazard receives the same agent density as the perimeter and preventing burn-through. Using this genuine OEM nozzle is a mandatory requirement for maintaining the UL listed status of an Industry Guard system -- the discharge must match the pre-calculated hydraulic design.
High Overhead vs. Low Overhead: Field Distinction
The 83-259270-000 high overhead nozzle lacks the heavy velocity-reduction screen of the low overhead (83-844258-000) model, preserving enough kinetic energy for the agent to reach the floor from ceiling mount heights. The low overhead version features a dense screen specifically to soften the discharge for proximity mounting above dip tanks, where splash prevention is critical. Substituting a high overhead nozzle in a low overhead application will cause dangerous splashing; using a low overhead nozzle at ceiling height will result in the agent floating away in the ventilation draft.

Blow-Off Cap Mandate
In paint booth and spray environments, the orifice is constantly exposed to overspray. Every 83-259270-000 must be fitted with an OEM replacement cap to prevent the internal strainer from becoming blocked by hardened paint. The cap pops off instantly under system discharge pressure.
Orifice and Plating Audit
During each semi-annual NFPA 17 inspection, verify that the nickel-chrome plating is intact. Peeling plating can trap dry chemical agent in the orifice, causing internal caking that restricts flow. Any nozzle showing obstruction or plating failure must be replaced immediately.
Alignment Verification
High-ceiling nozzles are susceptible to being knocked out of alignment during facility maintenance. A nozzle aimed even 10 degrees off-target can leave a significant shadow zone where a fire can continue to burn unchecked. Verify aim at every inspection using the system's as-built drawings.
Can this nozzle be used in a Range Guard wet chemical system?
No. The 83-259270-000 is calibrated for the particle size and flow dynamics of dry chemical agents. Using it in a wet chemical system will cause an immediate clog and system failure.
Which agent types are compatible?
The nozzle is designed for all standard dry chemical agents, including ABC powder, BC agent, and Purple-K. It is not compatible with wet chemical or foam agents.
Does this nozzle include mounting hardware?
No. The part number refers to the nozzle body only. Installation requires a standard 3/8" NPT connection to the discharge piping. Mounting hardware must be sourced separately based on the ceiling substrate and installation configuration.
