What is a AFFF Foam Proportioner
AFFF foam proportioner is a device that accurately mixes Aqueous Film-Forming Foam (AFFF) concentrate with water to create fire-suppressing foam. It ensures the correct ratio (typically 1–6%) for optimal fire knockdown in flammable liquid (Class B) fires.
How It Works:
Water Flow: Incoming water creates a pressure differential, drawing foam concentrate into the stream.
Mixing: Uses a venturi, bladder tank, or balanced-pressure system to blend concentrate and water.
Output: Delivers foam solution to nozzles/cannons for application.
Key Features:
Ratio Control: Adjustable for varying fire risks (e.g., 3% for hydrocarbons, 6% for polar solvents).
Materials: Corrosion-resistant (stainless steel, brass) for harsh environments.
Types: Inline (fixed systems) or portable (apparatus-mounted).
Applications: Fuel storage, airports, chemical plants, marine firefighting.
Standards: Complies with NFPA 11/16; tested for reliability under high flow/pressure.
Maintenance:
Flush with water post-use to prevent residue.
Regularly inspect seals, valves, and concentrate levels.
