Production introduction
Engineered for efficiency, Fire Foam Afff 1000L delivers a powerful foam blanket that smothers hydrocarbon fires-including gasoline, diesel, and crude oil-by blocking oxygen and cooling the fuel surface. Its surfactant blend ensures a surface tension of 16.1–17.8 mN/m, enabling swift spread across liquid surfaces, while an expansion ratio of 6.8±1 produces dense, adherent foam. The 1000L capacity makes it ideal for refineries, tank farms, and industrial facilities requiring continuous foam supply during extended firefighting operations.
Fire Foam Afff 1000L maintains stability in temperatures from -15°C to 45°C, resisting freezing and thermal degradation. The drum's UV-resistant design protects the concentrate from sunlight, preserving its chemical integrity. When diluted with water (per 3% or 6% ratios), it generates foam with a 25% drainage time of 4.0–4.8 minutes, ensuring long-lasting suppression. Its compatibility with standard proportioning systems and pump units simplifies integration into existing firefighting infrastructure.
Beyond emergency use, Fire Foam Afff 1000L supports preventive maintenance-regular testing of foam quality (via expansion and spread rate checks) ensures readiness. The drum features a reinforced bung for easy pumping or gravity feeding, and its stackable design saves storage space. For facilities handling large volumes of flammable liquids, Fire Foam Afff 1000L offers a reliable, high-capacity solution to mitigate risks and protect assets.

FAQ
Q: What is the optimal way to transfer Fire Foam Afff 1000L from the drum to firefighting systems?
A: Use a dedicated centrifugal pump with a 2-inch hose to avoid aeration, which can degrade foam quality. Alternatively, utilize the drum's bottom outlet for gravity feeding into proportioning tanks, ensuring the transfer rate matches system demand.
Q: How does temperature fluctuation affect the shelf life of Fire Foam Afff 1000L?
A: Prolonged exposure to temperatures above 50°C or below -20°C can shorten shelf life to 5–6 years (from the standard 8 years). Store the drum in a climate-controlled area, and avoid direct contact with heat sources like boilers or sunlight.
Q: Can Fire Foam Afff 1000L be used in mobile firefighting units (e.g., fire trucks)?
A: Yes, but secure the drum with anti-roll brackets to prevent movement during transit. Use a pressure-regulated transfer pump to feed foam into the truck's proportioning system, ensuring consistent flow rates during vehicle motion.
Q: What safety measures are required when handling spilled Fire Foam Afff 1000L?
A: Contain spills with absorbent booms to prevent runoff into drains. Neutralize small spills with lime (to adjust pH) before disposal. For large spills, contact hazardous waste services-avoid direct contact with skin, as concentrated foam may cause mild irritation.
Q: How to verify the concentration of Fire Foam Afff 1000L after long-term storage?
A: Take a 500ml sample and test its refractive index using a refractometer-readings should match the manufacturer's specs (1.338–1.342 for 3% concentrate). Deviations indicate degradation, requiring replacement.
