What is foam proportioner
foam proportioner is a device that mixes firefighting foam concentrate with water at a precise ratio (1–6%) to create effective fire-suppressing foam. It ensures optimal foam expansion for smothering flammable liquid (Class B) fires.
Types:
Balanced Pressure: Uses pumps and valves for consistent ratios under varying pressures.
Venturi: Relies on water flow to draw concentrate via suction (no power needed).
Key Features:
Adjustable ratios for different fuels (3% for hydrocarbons, 6% for polar solvents).
Durable materials (stainless steel, brass) for corrosion resistance.
Compatible with AFFF, AR-AFFF, or eco-friendly fluorine-free foams.
Applications: Fuel tanks, airports, chemical plants, marine firefighting.
Standards: Meets NFPA 11/16 for reliability and safety.
Maintenance:
Flush with water post-use to prevent clogging.
Inspect seals, valves, and concentrate levels regularly.
