Unlike dry chemical extinguishers, the SF-15CO2 discharges clean CO2 gas that leaves no residue, making it the preferred choice where protecting sensitive electrical equipment or avoiding cleanup downtime is a priority. The combination of a D.O.T.-approved aluminum cylinder, stainless steel hardware, and a polyester powder coat finish gives this unit a corrosion resistance advantage in harsh or marine environments where lesser-constructed units would degrade prematurely. Color and bar-coded labels further simplify accurate inspection and service tracking.
Key Features & Benefits
Industrial-Strength Aluminum Cylinder
The D.O.T.-approved aluminum cylinder provides a high strength-to-weight ratio suited for demanding job site and industrial environments. Aluminum construction also contributes to the unit's corrosion resistance, extending service life in humid or chemically active settings.
Superb Corrosion Resistance
A super durable polyester powder paint finish combined with stainless steel handles, pull pin, and retaining chain makes the SF-15CO2 well suited for corrosive environments such as marine, chemical processing, or coastal installations. This level of hardware quality reduces the risk of component failure during an emergency.
Chrome-Plated Solid Brass Valve
The chrome-plated solid brass valve delivers reliable actuation and long-term durability under pressure. Brass valve construction is a recognized standard for dependable performance in fire suppression equipment.
Impact-Resistant Horn
The strong impact-resistant horn is designed to withstand the rigors of job site handling and repeated use. A durable horn ensures consistent CO2 discharge direction and flow during an emergency event.
Wide Operating Temperature Range
Rated from -22°F to 120°F (-30°C to 49°C), the SF-15CO2 remains operational across a broad range of environmental conditions, from cold storage facilities to hot industrial spaces. This range ensures the unit is ready to perform regardless of ambient temperature extremes on the job site.
Color and Bar-Coded Labels
Color and bar-coded labels are designed for accurate service and inspection tracking, reducing the chance of service errors during annual maintenance. This feature supports compliance with NFPA 10 inspection requirements.
U.S.C.G. Approved with Listed Bracket
U.S. Coast Guard approval (Type B:C Size II) with the bracket listed on the label makes the SF-15CO2 a compliant choice for marine vessel applications. The bracket listing simplifies installation verification for marine inspections.
Common Applications
Electrical Equipment Rooms
CO2 extinguishes Class C electrical fires without leaving conductive or corrosive residue, making it ideal for server rooms, switchgear rooms, and control panels where equipment damage from agent contamination must be avoided.
Flammable Liquid Storage and Handling Areas
The SF-15CO2 is rated for Class B fires involving flammable liquids and gases, making it appropriate for fuel storage areas, paint booths, and chemical handling facilities.
Marine and Coastal Environments
U.S.C.G. approval and superior corrosion-resistant construction make this unit a compliant and durable choice for marine vessels and coastal installations where salt air accelerates corrosion on lesser-built equipment.
Industrial and Manufacturing Facilities
The heavy-duty construction and corrosion-resistant finish suit the SF-15CO2 for placement in manufacturing plants, machine shops, and processing facilities where both flammable liquids and electrical hazards are present.
Commercial Kitchens and Food Service Support Areas
Where Class B and C hazards exist in food service support areas (e.g., generator rooms, electrical panels), a clean-agent CO2 extinguisher avoids contaminating food preparation surfaces with dry chemical residue.
Compatible Materials
- Flammable liquids and gases (Class B fires)
- Electrical equipment and energized wiring (Class C fires)
- Gasoline, diesel, and petroleum-based fuels
- Solvents, paints, and lacquers
- Electrical panels, switchgear, and control equipment
- Generators and motors

Q: Does the SF-15CO2 have U.S. Coast Guard approval?
A: Yes. The SF-15CO2 carries U.S.C.G. approval as Type B:C Size II, with the approved bracket listed on the label, making it suitable for marine vessel use.
Q: What standards does the SF-15CO2 meet?
A: It meets or exceeds ANSI/UL 154, ANSI/UL 711, CAN/ULC-S503, CAN/ULC-S508, and complies with the NFPA 10 Standard for Portable Fire Extinguishers.
Q: What mounting brackets are available for the SF-15CO2?
A: The SF-15CO2 comes with a standard Wall/VB bracket. The HDVB-3 is available as an optional heavy-duty bracket.
Q: Why choose a CO2 extinguisher over a dry chemical unit for electrical hazards?
A: CO2 discharges as a clean gas and leaves no residue, so it will not damage or contaminate sensitive electrical equipment. Dry chemical agents can leave corrosive powder that requires extensive cleanup and may cause additional equipment damage.
Q: What is the discharge time and effective range of the SF-15CO2?
A: The SF-15CO2 has a discharge time of 17 seconds and an effective range of 6–12 ft (2–2.5 m).
