Buckeye 50 lb CO2 Wheeled Fire Extinguisher 20-B:C

Carbon dioxide is the original clean agent — it leaves no residue, conducts no electricity, and dissipates completely after discharge. For high-value electronic environments where water, dry chemical, or foam would cause more damage than the fire itself, CO2 is the only practical choice. A 50 lb wheeled unit extends that protection from cabinet-scale to room-scale. Buckeye Fire Equipment makes this model rated 20-B:C, with a 6061 TG aluminum cylinder, brass valve, and the long discharge hose and horn assembly characteristic of wheeled CO2. Listed to the ANSI/UL 154 carbon dioxide fire extinguisher standard and tested under UL 711 fire-test classification. USCG approved for marine use.

Primary use cases are data center white space, telecom switching rooms, broadcast studios, generator rooms, transformer pads, machine shops, laboratories, and clean rooms. IT equipment room fire protection under NFPA 75 data center fire protection guidance specifically calls out clean agents over water or dry chemical for primary protection. Portable wheeled CO2 extends fixed clean-agent systems governed by NFPA 2001 clean-agent suppression systems. For an overview of agent selection across CO2, Halotron, and dry chemical for sensitive equipment, see our fire extinguisher guide for sensitive electronics.

Two safety considerations that scale with capacity: CO2 produces no lingering suppression, so fuel above its autoignition point can reflash once the gas disperses. And a 50 lb discharge into a confined space can displace enough oxygen to endanger occupants — size to room volume per NFPA 12. Outdoor or open-bay installations don't have this risk. OSHA 29 CFR §1910.157 workplace extinguisher rules apply in parallel for employer-provided units.

Operating temperature range of -22°F to +120°F. Mobile cart, solid rubber tires, brass valve, black discharge horn. DOT compliant, USCG Type B:C Size II approved.
