Compressed Air Foam Mist Fire Suppression System
Products Description
Compressed Air Foam Mist (CAFM) is an advanced fire suppression technology that combines the strengths of compressed air foam and fine water mist to create a highly effective, efficient, and eco-conscious fire control system. It works by blending foam concentrate, water, and compressed air through a specially designed mixing chamber or nozzle system. The result is a stable, expanded foam mist that delivers superior fire performance with minimal water usage.
How CAFM Works:
1.Compressed air energizes and expands the foam solution, forming microbubbles. 2.These microbubbles are discharged as a dense mist or light foam blanket through nozzles or lances. 3.Upon contact with flames and hot surfaces, the foam mist rapidly cools, suffocates the fire, and forms a barrier to prevent re-ignition. 4.The mist form ensures deep penetration and full coverage, even in hard-to-reach or complex spaces.
Standard : CAFS Foam Mist Fire System was designed according to NFPA 11 Standard.
Discharge concentration: ≥1.63LPM,
Discharge duration time : ≥10mins.
Nozzle flow rate: 1.0L/S.
Working Pressure: 0.8~1.0MPa
Gas Bottle Filling Pressure: 15MPa.
Fire Agent: AFFF3% FOAM
We can provide you customized product as you request, and design fire system, and also provide instrucation&training for installation.
Products Advantages
• Dual-Class Fire Protection: Effectively suppresses Class B (flammable liquid) and Class C (electrical) fires
• Minimal Water Usage: Reduces collateral damage to electrical components and sensitive equipment
• High Heat Absorption: Fine mist droplets absorb heat quickly, helping lower temperatures and prevent thermal runaway.
• Fast Knockdown Time: Rapid fire suppression within 30–180 seconds, depending on hazard size
• Eco-Friendly Foam Agents: Available with fluorine-free and biodegradable options
• Safe for Energized Equipment: Non-conductive mist makes it safe for use on live transformers and electrical enclosures.
