Foam Concentrate

Class A & Class B Fire Suppression Foam

Firefighting Foam concentrates deliver the power and precision responders need when water alone isn’t enough. The collection at Shop Darley spans cutting-edge chemistries, from low-viscosity Class A agents that soak deeply into wildland fuels for faster knock-down and mop-up to specialty 1% A/B concentrates engineered for mixed-hazard departments that routinely pivot between structural and flammable-liquid incidents. Environmentally responsible options dominate the lineup: PFAS‑free and fluorine‑free formulations meet today’s rigorous regulatory standards without sacrificing expansion ratio or burn‑back resistance, including 3 × 6 % blends for large‑scale industrial suppression and next‑generation 3 × 3 non‑fluorinated foams that seal polar‑solvent vapors in seconds.

Airport and military crews will also find Mil-Spec SFFF products designed explicitly for runway fuel-spill scenarios. At the same time, municipal users can rely on long-shelf-life Class A Plus foams that enhance wetting action, reduce water consumption, and clean up easily. Whether you’re protecting the wildland-urban interface, petrochemical facilities, or aircraft operations, these concentrates integrate seamlessly with existing proportioning systems and deliver reliable performance in fresh, brackish, or saltwater.
