Product Details
the CLOUD® AERO is a compact, self-activating aerosol fire suppression device designed to help suppress fires before they spread.
Designed specifically for enclosed 3D printers, heated chambers, HotBoxes, enclosed CNC machines, enclosed laser engravers/cutters, electrical cabinets, and similar equipment, the CLOUD® AERO activates automatically under sustained high heat and releases a condensed aerosol fire suppression agent that interrupts the combustion process at a chemical level.
Unlike traditional powder extinguishers, the CLOUD® AERO:
- Requires no wiring or external power
- Requires no maintenance or servicing
- Leaves minimal residue
- Is generally safe for electronics and PCBs
- Has no pressurized tank or explosive discharge
- Provides continuous passive protection for up to 10 years
The CLOUD® AERO is most effective in enclosed spaces where the aerosol agent can remain concentrated around the fire source long enough to fully suppress combustion.
For open-frame printers or open equipment, effectiveness may vary depending on airflow, mounting position, and fire location. Whenever possible, use inside an enclosure for best performance.
Available in 2 sizes: the CLOUD® AERO and the CLOUD® AERO XL
The CLOUD® AERO is engineered to provide simple, passive fire suppression protection for:
- Enclosed FDM 3D printers
- Resin printers in enclosures
- Heated print chambers and HotBoxes
- Enclosed laser engravers and cutters
- Enclosed CNC equipment
- Electrical cabinets and control boxes
The unit automatically activates under sustained high heat conditions and releases a condensed aerosol agent designed to suppress developing fires quickly at the source.
- Best performance is achieved in enclosed spaces
- Mount high in the enclosure where heat and flames will rise
- Position near likely ignition sources when possible
- Open-frame machines may reduce effectiveness due to airflow dispersion

Simple Installation
Clean the surface where the patch will be placed with isopropyl alcohol and a paper towel (not a rag or cloth).
Place the Velcro patch onto the surface and let it cure for 24–48 hours before mounting the Cloud.
No wiring, plumbing, sensors, batteries, or maintenance required.
Each CLOUD® AERO includes:
- Velcro Hook backing pre-installed on the device
- Velcro Loop mounting plate with strong 3M adhesive
For best performance:
- Mount near the top of the enclosure
- Position above likely ignition sources:
- Hotend
- Heated chamber
- Mainboard/electronics
- Power supply
- Keep reasonably close to where heat and flames are likely to rise
The CLOUD® AERO is optimized for enclosed spaces where the extinguishing aerosol can remain concentrated around the fire source.
Recommended applications:
- Enclosed 3D printers
- Printers inside HotBoxes
- Enclosed CNC machines
- Enclosed laser engravers/cutters
- Electrical cabinets
The CLOUD® AERO may still provide protection on open-frame printers, however:
- Airflow may disperse the aerosol agent
- Effectiveness depends heavily on placement and surrounding conditions
- Enclosures are strongly recommended for best suppression performance
This allows quick installation on most surfaces without drilling or modification.
