Product overview
CHEMGUARD EXTREME CAFS is a Class A foam concentrate developed for compressed air foam systems. The solution reduces water surface tension and can form a foam layer that helps water remain in contact with combustible surfaces. The published dilution varies by CAFS, handline and aerial delivery method; there is no single concentration for every application. Select the foam quality, compatible metering equipment and available water supply together. The manufacturer also documents wetting-agent use, which should be distinguished from a complete foam-system listing. Confirm the current container, batch and safety data before supply and commissioning.

Key features
- Product: EXTREME CAFS Class A foam concentrate
- CAFS dilution: 0.1–1.0%
- Air-aspirating handline dilution: 0.3–0.5%
Applications
Compatible CAFS and Class A handline firefighting, exposure-protection foam and documented aerial delivery arrangements. The proportioning setting must match the delivery equipment and intended foam quality; current manufacturer instructions govern the final configuration.
Selection and project integration
Provide UDCT with the fuel or test application, required capacity, available water pressure and flow, selected concentrate and compatible equipment. Confirm the exact part numbers, coupling threads, storage conditions and current manufacturer instructions. For foam systems, use the fuel-specific application criteria and approved proportioning/discharge assembly; commissioning must verify the actual hydraulic and proportioning performance.
