CAFS Fire Truck , also named CAFS fire engine or CAFS fire tender, is a highly efficient fire-fighting vehicle equipped with a compressed air foam fire extinguishing system. CAFS fire truck is normally used to mix water, foam liquid and compressed air in proportion to generate high-stability fire extinguishing foam.
CAFS (Compressed Air Foam System) fire truck represents an innovative fire suppression apparatus that integrates water, foam concentrate, and compressed air to generate highly effective firefighting foam. Unlike conventional water-based systems, this technology produces a homogeneous foam mixture with a stable bubble structure, significantly enhancing fire-extinguishing efficiency.
Urban Response CAFS Units
Tailored for densely populated areas, these compact trucks prioritize maneuverability in narrow streets. Equipped with mid-range foam tanks (500–1,500 liters) and high-pressure pumps, they excel in suppressing structural fires while minimizing water damage.
Rapid Intervention Vehicles (RIVs)
Compact chassis-mounted units (GVWR ≤12 tons) prioritize agility for urban settings. Equipped with 500–800-liter CAFS pods and 360° discharge nozzles, they support narrow-access firefighting.
Industrial Hazard-Specific CAFS Rigs
These heavy-duty units target chemical or flammable liquid fires at refineries or airports. They employ alcohol-resistant foam concentrates and explosion-proof components. Multi-channel CAFS systems allow simultaneous application of different foam types.
CAFS employs adjustable nozzles to project foam in varying patterns, such as straight streams or wide sprays. The foam’s low water content allows it to cling to vertical surfaces and penetrate deep into combustible materials
Rapid Fire Suppression
CAFS (Compressed Air Foam System) fire trucks excel in extinguishing flames swiftly by deploying a high-expansion foam mixture. This foam, generated by blending water, foam concentrate, and compressed air, forms a cohesive blanket that smothers fires by cutting off oxygen.
Preventing Rekindling
The foam’s residual coating acts as a thermal barrier, reducing the risk of reignition. This is particularly vital in wildfires or industrial settings with flammable materials, where hidden embers or residual heat can reignite.
Hazardous Material Incident Mitigation
CAFS foam acts as a barrier during chemical or fuel-related emergencies, suppressing vapors and preventing explosive reactions. Its blanketing effect isolates hazardous substances, reducing risks to responders and communities.
