Industrial Fire Suppression Systems for Paint Booths

By AmerexIn Fire Extinguishers

Paint spray booths are essential across industries—from automotive refinishing to manufacturing and even theme parks. While they create a controlled environment for high-quality finishes, they also introduce a serious fire risk.

The Hidden Fire Risks Inside Paint Booths

Paint booths are designed to isolate the spray application process and control airflow, but in doing so, they also concentrate hazardous materials. During spraying, flammable paints and solvents are atomized into fine particles and vapors that can ignite easily. While these booths continuously draw in fresh air and exhaust contaminated air, overspray, and fumes, the vapors themselves are often both toxic and highly flammable, creating a potentially dangerous environment if ventilation or control systems fail.

Even under proper ventilation, ignition sources such as static electricity, electrical components, or mechanical failures can quickly spark a fire. This combination of fuel, oxygen, and potential ignition makes paint booths one of the highest-risk areas in industrial settings. For this reason, a reliable fire suppression system is essential to ensure safety and protect both personnel and operations.

Why You Should Choose Amerex

Amerex Industrial Fire Suppression Systems are designed to fit both open front paint spray booths (OFPSB) and vehicle paint spray booths (VPSB), delivering reliable, code-compliant protection for high-risk industrial finishing environments.

Amerex provides industry-leading protection for OFPSBs up to 18’6” in height— enabling broader protection of large or specialized operations. The design also accommodates crane slot openings in the booth ceiling, supporting operational flexibility without compromising fire protection.

For VPSBs, Amerex offers efficient total flood solutions:

  • A single Total Flood Perimeter (TFP) nozzle can protect up to 2,720 cubic feet.
  • Many common paint spray booths can be protected with just two nozzles (known as the 2-nozzle system), reducing complexity and cost.

Amerex offers flexible system configurations, giving facilities the choice between:

  • Mechanical Release Modules (MRM) for link-based detection.
  • Pneumatic Release Modules (PRM) for continuous tubing detection.

Both are designed to adapt to complex layouts and maximize protection coverage.

Unwavering Compliance, Ensured Safety

In addition to the best performance in the industry, Amerex Industrial Fire Suppression Systems have been tested and listed to the UL1254 Standard. They also comply with NFPA 33, ensuring the safest and most reliable products on the market. NFPA 33 is the national safety standard that provides requirements to mitigate fire and explosion hazards of spray application processes using flammable or combustible materials.
