Product guide
A 3 kg CO₂ extinguisher is a handheld fire protection unit that has 3 kg of pressurized carbon dioxide gas. This type of fire protection is used mainly to put out Class B (liquid fuel) and Class E/C (electrical) fires. It operates on the principle that the gas expands very quickly to become a cold gas which displaces the oxygen needed for the fire to continue burning. Because it does not leave any residue, it is considered the best choice for protecting sensitive equipment and expensive technology systems from damage while providing fire protection.
Carbon dioxide gas is a non-conductor of electricity and leaves no residue after use, making it an ideal choice for placement in specific areas.
Server Rooms & IT Hubs: Protects network racks and computers against electrical fires.
Commercial Office & School: Location where there are large numbers of printers, computer systems, and household appliances.
Laboratories & Workshops: Controls electrical control panels effectively, as well as manages small risks associated with chemicals and/or flammable liquids.
Exact specifications vary slightly by each manufacturer (for example, Safety 53 or Universal Fire Protection), however a typical 3 kg cylinder will have the following common performance characteristics:
Fire Extinguishing Agent: Carbon Dioxide (Pure CO₂)
Discharge Time: 8 to 14 seconds
Discharge Distance: 2 to 5 meters
Operating Pressure: High pressure (approximately 55 to 150 bar)
Total Filled Weight: Approx. 12.9 kg (due to heavy steel alloy casing)
Visual Indicators: Red body with a distinct black banner and a horn-shaped nozzle
Don't ever grab the horn: The liquid CO2 changes into a gas, and when that happens, the temperature goes down. If you hold onto the discharge horn, you could get really bad frostbite ("cold burn") on your hand. You should always use either the designated handle or an insulated grip to hold onto the horn.
Do not employ on kitchen fires: The violent forces that result from a CO₂ discharge may cause hot greases or burning oils to splash, resulting in an immediate spread of a Class F/K fire in a kitchen.
Class A Fires: Do not use this product on a class A fire (wood, paper, etc.) as the fire may appear to be out momentarily; however, the product cannot reach into the burning material to extinguish the embers and therefore there is a high risk that the fire will reignite.
After you deploy CO₂, make sure you ventilate the area. If you use CO₂ in small areas, the lack of oxygen may cause people inside to suffocate.
What is a CO2 fire extinguisher?
A CO2 fire extinguisher is an explicitly made safety equipment with high-pressure, which contains pressurized liquid carbon dioxide. The extinguisher has been specifically manufactured to put out Class B (flammable liquid) and electric fires through oxygen displacement and fuel cooling. Because the extinguisher leaves no residue, it is most suitable to protect electronic equipment that is sensitive.
How much is a 3kg CO2 fire extinguisher?
A typical cost of a 3kg CO2 fire extinguisher in Pakistan will be anywhere from PKR 6,800 to PKR 11,500 depending upon the manufacturer/supplier, quality, and brand. Certified or higher-end versions may cost as much as PKR 22,000.
What are the details of the 2 kg CO2 fire extinguisher?
Fire Rating: Typically 34B (this means that it can put out Class B fires caused by flammable liquids and also electrical fires).
Physical Characteristics: The total weight of the product is between 5.8kg and 8.5kg depending on the material used for construction of the cylinder (steel cylinders weigh more than aluminum ones). There is a large black discharge horn on the unit.
Performance: The discharge time is approximately 8 to 14 seconds with an effective throw range of 2 to 5 meters. Operation takes place at an internal pressure of 55 to 60 bar.
Key Feature: Since carbon dioxide (CO2) is stored at high pressures as a liquid, there is no pressure gauge. Therefore, you need to check how ready the device is by weighing it.
Why is CO2 used as a fire extinguisher?
Oxygen Displacement: Because CO2 is 1.5 times as heavy as air, when you spray it on a fire, it will displace the oxygen in the area, thus disrupting the "fire triangle" and extinguishing the fire.
Cooling Effect: As it exits the horn, it does so rapidly as a gas under high pressure, which is very cold (-60 C) and creates "dry ice snow," which removes heat from the burning fuel.
Clean and non-conductive: This gas will put out electrical fires safely, as well as being clean (no residue) so that after the fire has been extinguished there is no need for cleanup of chemical residues, and there is less risk of damage to expensive hardware.
