C352TS - H3R 2.5 lb. Red Fire Aviation Fire Extinguisher

C352TS – H3R Aviation 2.5 lb. Red Halon 1211 Handheld Fire Extinguisher

The H3R Aviation C352TS is a flight-critical, high-efficiency handheld fire extinguisher containing 2.5 lbs of pure Halon 1211 (bromochlorodifluoromethane) clean liquefied gas agent. Specially engineered for the demanding envelope of commercial, military, and general aviation aircraft, this model serves as the primary cockpit and cabin defense line against unexpected inflight fire emergencies. Deployed as a single-unit line replaceable unit (LRU), it provides rapid, high-pressure knockdown capability against flammable liquids and electrical fires without causing thermal shock or leaving behind corrosive residues that would permanently destroy mission-critical avionics or electrical wiring.

Manufactured by H3R Aviation, Inc., the C352TS features a premium drawn-steel cylinder with a minimum wall thickness of 0.028 inches, high-reliability all-metal valve assemblies, and an integrated visual pressure indicator gauge. The "TS" suffix indicates that the assembly includes the factory-supplied, FAA-DAR vibration-tested 817S double-strap transport bracket, which guarantees the unit remains securely bound to the airframe partition under high-amplitude harmonic resonance and landing impacts. Free from granular chemical powders that obscure vision and choke flight crews in enclosed cockpits, this specialized extinguisher utilizes low-pressure liquefied nitrogen propellant to cast a dense stream into hard-to-reach wiring bays and under-floor voids, ensuring maximum safety-of-flight integrity when containment is paramount.

The H3R Aviation C352TS represents the gold standard in airborne gaseous fire suppression, backed by rigorous ANSI/UL testing metrics and civil aviation operational mandates. Its structural layout minimizes empty weight while maximizing chemical punch, making it a mandatory component for aircraft ranging from single-engine pistons to wide-body commercial transports. For directors of maintenance, safety inspectors, and corporate flight operations managers, provisioning the C352TS guarantees strict compliance with FAA, EASA, and NFPA 10 standards, providing high operational readiness throughout its multi-decade service life.

Key Features

Why Choose C352TS?

Installing a genuine, factory-charged H3R Aviation C352TS Halon 1211 extinguisher avoids the severe operational safety failures linked to consumer dry-chemical alternatives. Commercial off-the-shelf dry powder extinguishers utilize monoammonium phosphate compounds that melt and fuse into a glass-like abrasive crust when exposed to flame temperatures. If discharged inside an aircraft cabin, this powder expands into a blinding, corrosive cloud that strips the insulation off copper wiring, ruins circuit boards across the primary avionics bus, jams flight control pulleys, and forces immediate emergency oxygen mask usage due to acute inhalation risks. The C352TS dispenses a pristine, volatile gas stream that neutralizes ignition chains without leaving a microscopic trace of destructive powder, ensuring that the aircraft's critical electrical infrastructure can continue to function to complete a safe precautionary landing.

The chemical function of the H3R Aviation C352TS relies on the principles of gaseous molecular chain-breaking and endothermic kinetic suppression. Unlike water, which cools a fuel load below its ignition point, or carbon dioxide, which attempts to displace ambient oxygen levels, Halon 1211 operates primarily at the atomic level within the combustion zone. When discharged from the C352TS nozzle as a flashing liquefied gas stream, the molecule undergoes thermal decomposition inside the flame, liberating highly reactive bromine radicals. These free radicals interact directly with the short-lived hydrogen and hydroxyl radicals that drive the exothermic propagation of a fire. Through a cyclical catalytic mechanism, the bromine radical binds with these active chain-carriers, forming stable compounds and effectively terminating the flame chain reaction without depleting cabin oxygen to levels hazardous to the flight crew. Because Halon 1211 possesses high vapor density and low surface tension, it penetrates hard-to-reach spaces via gas expansion, filling the non-symmetric structural spaces behind instrument panels to eliminate deep-seated arcs without causing thermal shock deformation on sensitive ceramic microchips and multi-layer printed circuit boards (PCBs).

Note: The H3R Aviation C352TS is a flight-critical life safety component subject to strict airworthiness directives and chemical transport rules. It is categorized as a Class 2.2 Hazardous Material (UN1044). In accordance with NFPA 10 and civil aviation operational procedures, this gauged extinguisher requires a mandatory visual check every 30 days to verify that the pointer rests within the green operational zone, an extensive internal maintenance inspection every 6 years, and a complete structural hydrostatic shell integrity test every 12 years calculated from the original stamped date of manufacture. Installation, positioning, and securement tracking must be carried out by a certified A&P mechanic or authorized avionics repair facility in strict compliance with the target airframe's approved Structural Repair Manual (SRM) or Standard Practices Manual (Chapter 26).
