Amerex 332 (20 lb) Carbon Dioxide Fire Extinguisher

Clean, Residue-Free Fire Protection for Sensitive Equipment

The Amerex 332 20 lb Carbon Dioxide (CO2) Fire Extinguisher provides clean, effective fire suppression without leaving any residue. Discharging as a white cloud of "snow," CO2 smothers fires by eliminating oxygen, making it ideal for protecting sensitive electronic equipment, laboratories, and areas where cleanup after discharge is a critical concern.

Why Choose the Amerex 332 CO2?

• 20 lb capacity – Maximum CO2 supply for extended firefighting capability and large-scale applications
• BC fire protection – Effectively fights Class B (flammable liquids) and Class C (electrical) fires
• Zero residue – Leaves no cleanup after discharge, protecting sensitive equipment and electronics
• Electrically non-conductive – Safe to use on energized electrical equipment without risk of shock
• Clean agent technology – Won't damage computers, servers, or delicate instruments
• Oxygen displacement – Smothers fires by removing oxygen from the fire triangle
• Durable construction – Built to professional standards for reliable performance
• Amerex quality – Manufactured by a trusted leader in fire protection equipment
• Rechargeable – Can be professionally serviced and recharged for long-term use

Ideal For:

Large server rooms, data centers, laboratories, clean rooms, museums, libraries, electrical rooms, telecommunications facilities, and any location with sensitive equipment or materials that cannot tolerate residue from traditional extinguishers.

What It Protects Against:

• Class B: Gasoline, oil, grease, solvents, paints, and other flammable liquids
• Class C: Energized electrical equipment, computers, servers, wiring, and circuit breakers

Why Choose CO2 Over Dry Chemical?

Carbon dioxide extinguishers offer unique advantages:

• Absolutely no residue or cleanup required after discharge
• Won't damage sensitive electronics or equipment
• Ideal for areas where contamination is unacceptable
• Electrically non-conductive for safe use on live electrical equipment
• Environmentally friendly with no chemical agents

Why Choose 20 lb Over Smaller Models?

The maximum 20 lb capacity provides:

• Longest discharge time for fighting large-scale fires
• Greatest coverage area for extensive spaces
• Most firefighting agent for stubborn or rapidly spreading fires
• Best suited for large data centers and industrial applications

How CO2 Extinguishers Work:

When discharged, carbon dioxide rapidly expands and cools, creating a white cloud of CO2 "snow" that displaces oxygen around the fire. By removing oxygen from the combustion process, the fire is quickly smothered. The CO2 then dissipates into the atmosphere, leaving no residue, powder, or liquid behind.

Important Safety Note: CO2 extinguishers discharge at extremely cold temperatures (-109°F). Avoid skin contact with the discharge horn during use. CO2 displaces oxygen, so ensure adequate ventilation after use in enclosed spaces. This extinguisher is NOT rated for Class A fires (ordinary combustibles like wood, paper, or cloth).

For Multi-Purpose Protection: If you need protection for Class A fires as well, consider our Amerex ABC Fire Extinguisher models.
