Why Ferosticker?

Instant Fire Interruption

Utilizes a potassium-based aerosol that chemically disrupts the combustion reaction by neutralizing free radicals, making it 3 to 10 times more effective than CO2 or Halon per unit of weight.

Zero Damage, Zero Mess

Unlike traditional dry chemical extinguishers that wreak havoc on aluminum, steel, and copper components, Ferosticker's clean agent leaves no corrosive residue, preventing costly repairs and engine ingestion scenarios.

Autonomous Activation (338°F / 170°C)

Triggers automatically at 338°F (170°C), a temperature high enough to avoid false alarms in hot engine bays but low enough to stop a fire before it becomes a total loss.

Maintenance-Free for 6 Years

A set-and-forget solution with a 6-year service life, eliminating the chore of periodic checks and avoiding costly annual servicing required by plumbed-in systems.

The Shield. It Earned Its Nickname.

"I was skeptical, because everything claims to be 'set-and-forget.' But after 6 months with Ferosticker in my RV's battery compartment and by the inverter, I actually feel it. That deep-seated worry about a lithium runaway fire? It's gone. Worth every penny for that peace of mind. Highly recommend to any serious RVer."

"After a scare on my last offshore trip, I knew I needed better engine bay protection. Traditional extinguishers are messy and destructive. Plumbed systems are a maintenance headache. Ferosticker is the elegant solution I've been waiting for. It's simple, autonomous, and the clean agent means no damage to my expensive electronics if it ever deploys. This is what modern boating needs."

Rated 5.0 / 5.0 | 'Excellent'

"My classic car's wiring is my biggest concern. I used to check it constantly. The Ferosticker gave me a modern solution for an old problem. It's discreet, easy to install, and knowing it's watching even when I'm not... that's huge. No messy powder, no visible bulk. It truly is invisible insurance."

The Science Behind Your Silent Sentinel

Ferosticker is based on aerosol fire-suppression technology originally developed for extreme environments, including space applications. When the activation element reaches approximately 170°C / 338°F or is exposed to direct flame, it automatically releases highly active potassium radicals that interrupt the chemical combustion process by neutralizing hydrogen, oxygen and hydroxyl radicals, suppressing the developing fire

Stop the fire. Not the printer.

Traditional powder extinguishers can leave sensitive equipment covered in difficult-to-clean residue. F03 uses condensed aerosol to suppress fire without the same powder mess, helping reduce secondary damage and cleanup.

Easy To Install

Peel

Pick a clean, flat spot inside the panel or compartment. Wipe it dry, then peel off the backing

Stick

Press it down firmly, above whatever could catch fire. No tools. No wiring.

Check

Leave about 2–3 cm of space around it. The aerosol needs room to spread.

* Ferosticker protects the compartment, not the room. That's the design: it stops the fire inside the enclosure, before it can spread into the room.

** Fire safety is built in layers. Ferosticker is the layer that goes where the others can't: inside the compartments where fires start.
