Hercules™ CAFS

Pierce Hercules CAFS Fire Truck Foam System control panel for a Pierce Fire Truck

5X More Effective Than Using Water Alone.



Water has high surface tension. Hercules™ CAFS, in contrast, offers a low surface tension, allowing it to spread quickly, cover more area and cling to the fuel source longer, giving the foam agent the ability to penetrate and cool material faster than water alone.

For a quicker and safer knockdown, with less exposure to heat for firefighters, consider Pierce Hercules CAFS. Hercules adds compressed air to your Husky™ foam system and provides better control of the foam bubble structures, allowing firefighters to gain control of fires faster, reduce water usage and lighten handlines while offering better exposure protection.

Our Hercules CAFS system perfectly complements any of our Husky foam systems. Concerned about space? All the controls easily fit on any pump panel for easy and organized operation.
