Production introduction
Foinbo® Low Expansion Foam Branch Pipe (LEFBP) is a specialized firefighting apparatus designed to generate and project low-expansion foam solutions for suppressing Class A (ordinary combustibles like wood) and Class B (flammable liquids/gases) fires. As a critical component of industrial and municipal fire protection systems, this device combines mechanical foam generation with ergonomic handling to deliver rapid fire control in high-risk environments such as oil refineries, chemical plants, aircraft hangars, and fuel storage facilities.
- Flow Capacity: Ranges from 225 LPM to 960 LPM , accommodating varying fire loads.
- Operating Pressure: Nominal range of 7 bar (100 psi), with minimum thresholds of 4.5 bar (65 psi) to ensure adequate foam quality.
- Throw Distance: Up to 40 meters for high-flow models, enabling safe standoff distances in large-scale incidents.

FAQ
Q: What is a Low Expansion Foam Branch Pipe (LEFBP)?
A: A firefighting nozzle designed to generate and project low-expansion foam (expansion ratio 5:1–20:1) for suppressing Class A and Class B fires.
Q: What is the primary function of an LEFBP?
A: To create a dense foam blanket that starves flames of oxygen, cools the fuel surface, and prevents re-ignition.
Q: What types of fires can LEFBPs extinguish?
A: Class A (solids like wood) and Class B (flammable liquids like gasoline).
Q: How does a self-inducting LEFBP work?
A: It automatically meters foam concentrate at a fixed ratio (e.g., 1%–6%) using an integrated educator.
Q: What is the minimum operating pressure for an LEFBP?
A: Typically 4.5 bar (65 psi) to ensure adequate foam expansion and throw distance.
