A344T – H3R Aviation 2.5 lb. Halon 1211 Fire Extinguisher (Red)
Part Number: A344T
Manufacturer: H3R Aviation
Standard Series: Halon 1211 (Handheld)
Certification: FAA / UL Listed (7B:C)
Overview Section
The A344T is a professional-grade Halon 1211 fire extinguisher specifically engineered for the confined spaces of aircraft cockpits and cabins. While the net weight of the Halon agent is 2.5 lbs. (contributing to a total weight of approximately 3.4 lbs.), it remains one of the most compact and powerful fire suppression tools available for General Aviation and Business jets.
Utilizing Halon 1211 (Liquefied Gas), the A344T is a "Clean Agent" extinguisher.1 It is designed to stop fires by chemically interrupting the combustion chain reaction without leaving behind any powdery residue or "cold-shocking" sensitive avionics. This makes it the industry-standard choice for pilots of Cessna, Beechcraft, and Cirrus aircraft who need immediate fire suppression capabilities without the risk of collateral damage to their electronic flight displays.

Advanced Engineering & Structural Application
The A344T is engineered for Non-Conductive Fire Suppression. In an aircraft, fire usually occurs in one of two places: the engine compartment or behind the instrument panel.
Engineering Insight: The Halon 1211 Advantage
Unlike dry chemical extinguishers (which utilize corrosive ABC powder), the A344T discharges a "streaming" gas. This gas can penetrate hard-to-reach areas—such as behind a G1000 display or under a seat—where a dry powder might not reach.2 Furthermore, because Halon 1211 is a non-conductive gas, it will not cause short circuits or "freeze" delicate circuit boards, allowing you to salvage your avionics suite after a fire event.
Compact Pressure Vessel
The A344T utilizes a high-strength aluminum cylinder that is much lighter than steel counterparts. This helps operators meet strict "Useful Load" requirements. The high-quality chrome-plated brass valve assembly and large pull-ring are designed for one-handed operation under the high-stress environment of an in-flight fire.
Aircraft Compatibility
The A344T is the "go-to" extinguisher for various cockpit configurations:
Cessna 172/182/206: Fits perfectly in the standard floor-mounted bracket.
Beechcraft Bonanza/Baron: Common cockpit side-wall installation.
Cirrus SR20/SR22: Often used as a primary or secondary cabin safety item.
Experimental Aircraft: The preferred choice for Van’s RV builders due to its weight-to-power ratio.
The H3R Aviation A344T is an essential piece of safety equipment for every pilot. When an electrical fire breaks out behind your panel, you cannot afford to use an extinguisher that leaves a corrosive mess or damages your expensive radios. This 2.5 lb. Halon 1211 unit provides a powerful 7B:C rating in a lightweight, red-painted aluminum body that is easy to locate in an emergency. Trusted by pilots worldwide, the A344T offers the peace of mind that comes with a "clean agent" discharge that stops fires instantly without compromising your airframe or avionics.
Installation & Maintenance Addendum
Mounting: Ensure the A344T is mounted in the provided 817S bracket and is easily accessible from the pilot's seat. It should not interfere with the movement of the flight controls or rudder pedals.
Monthly Inspection: Check the pressure gauge monthly to ensure the needle is in the Green Zone. Verify that the safety pin is in place and the plastic seal is intact.
Recertification: Halon extinguishers do not expire, but they should be weighed annually and hydrostatically tested according to local regulations (typically every 12 years).
