FK-5-1-12 (or FK5112) is the chemical name of a type of clean agent fire extinguisher.
In terms of application, FK5112 is commonly used in areas where chemical powder residues are not desired after discharge, such as electrical rooms, server rooms, data centers, MDB panels, control panels, or areas with critical electronic equipment. However, the actual choice of application should be considered in conjunction with the product model, instructions for use, site conditions, and the specific technical documents of that product.

How is FK-5-1-12 related to Perfluorohexanone?
FK-5-1-12 and Perfluorohexanone are the same chemical substance, just named differently according to nomenclature and application standards.
Perfluorohexanone is the common chemical name describing the structure of this substance. It is a ketone with 6 carbon atoms (Hexa) and all hydrogens replaced by fluorine (Perfluoro), having the chemical formula C6F12O.
FK-5-1-12 is the international code name designated by standard organizations such as ASHRAE and ISO to refer to this clean fire extinguishing agent in the fire protection industry.

How is PAF-222 related to FK-5-1-12?
PAF-222 is a product solution from PAF GLOBAL that utilizes clean extinguishing agents in the FK-5-1-12 family, which are available in various formats depending on the model and design, such as clean agent fire extinguishers, automatic fire extinguishing devices, or fire suppression systems for critical areas.
However, this section does not focus primarily on explaining the details of PAF-222, but is intended to help readers understand the type and name of the chemical before making a decision. If you would like to study the product details directly, you can read more here. [What is PAF-222]
Why FK-5-1-12 is Used as a Clean Fire Extinguishing Agent
FK-5-1-12 is widely used in clean agent fire suppression systems because it effectively reduces impact and damage after discharge. It is ideal for areas housing electrical equipment, electronics, or high-value assets that should not come into contact with residues or chemical powders.
Leaves No Powder Residues
No residue and non-conductive (Clean & Non-conductive): When discharged, the agent vaporizes completely into gas. It leaves no difficult cleanup after use and does not conduct electricity, thus preventing damage to IT servers, electronic devices, or critical documents.

High Electrical Insulation Protection
FK-5-1-12 in both liquid and vapor states has electrical resistance, or dielectric strength, approximately 2.3 times higher than dry air.
This means that even if you discharge this agent onto live, operating electrical equipment with electrical current running through it, the agent will not cause electrical shock. You can read more here. [What is Non-Conductive (Dielectric)]
Highly Effective and Device-Safe Fire Suppression Properties
Rapid Fire Suppression: FK-5-1-12 suppresses fire primarily on the principle of a cooling effect, absorbing heat from the scene and interrupting the chemical reaction of combustion, allowing it to extinguish fires very quickly.
Environmentally Friendly
No Ozone Depletion Potential: Ozone Depletion Potential (ODP = 0)
No Impact on Global Warming: Global Warming Potential (GWP < 1) which is extremely low.
Fast Atmospheric Dispersal: It has an atmospheric lifetime of only about 5 days, meaning it does not accumulate in nature for long.
Safety for Humans
Some gas fire extinguishing agents (such as CO2 or certain inert gases) extinguish fires by "oxygen displacement" to lower oxygen levels, which can cause people in the room to suffocate and lose consciousness.
But FK-5-1-12 suppresses fire by "absorbing heat" away from the fire.
What areas are suitable for FK-5-1-12?
With properties of being non-conductive, residue-free, safe for humans, and environmentally friendly, the fire extinguishing agent FK-5-1-12 is ideal for "enclosed areas containing high-value assets or devices sensitive to moisture and chemical residues."
Data Centers / Server Rooms: Rooms housing server racks
Control Rooms / Network Rooms: Rooms managing network and communication systems
Telecom Switches / Base Stations: Telecommunication exchange stations
Libraries & Museums: Protecting antiquities and artwork
Document Archives: Contracts, accounts, or critical legal records
Bank Vaults: Secure areas storing safes and valuables
Labs & Cleanrooms: Containing analytical instruments or reactive chemicals
Medical Imaging Rooms: Such as cultivation rooms, MRI or CT Scan rooms
Pharmaceutical Facilities
Plant Control Rooms: In industrial factories, power plants, or oil refineries
Switchgear & Electrical Rooms: MDB panels or high-voltage control cabinets
Generator Rooms / UPS Rooms
Engine Rooms & Yachts: Certified by international maritime organizations (such as DNV, ABS)
Aviation Control Towers: and Flight Simulators

How is FK-5-1-12 different from other fire extinguishing agents?
Comparing FK-5-1-12 with other popular fire extinguishing agents helps illustrate the differences most clearly across dimensions of effectiveness, human safety, environmental impact, and equipment protection as follows:
Environmental Aspect: This is the biggest difference. HFCs group agents, which have a high GWP of up to 3,220 (causing global warming), are being phased down under the Kigali Amendment, whereas FK-5-1-12 has a GWP of < 1, so there is no risk of being banned in the future.
Life Safety: CO2 extinguishes fire by diluting oxygen in the room below levels humans can breathe, making it life-threatening if discharged in an occupied room. Meanwhile, FK-5-1-12 extinguishes fire by absorbing heat, allowing people to continue breathing and evacuate safely.
Post-Discharge Damage: Dry chemical powder leaves fine powder residues scattered across the room, which corrodes circuit boards and causes permanent damage. In contrast, FK-5-1-12 vaporizes 100% completely, leaving absolutely no residue behind.
