Production introduction
The foinbo® Class A/B/C Fire Foam Proportioner delivers all-in-one foam mixing performance, tailored to tackle the full spectrum of Class A, B, and Class C fire hazards across industrial and commercial facilities. Built on balanced pressure technology, it injects foam concentrate into the water line at a precise 3–3.9% mixing ratio, adapting seamlessly to varying water flow and pressure. Rated for 1.2MPa working pressure, it supports mixed liquid flow rates from 8–250 L/S across PHP32 to PHP250 models, making it suitable for everything from small warehouses to sprawling petrochemical complexes.
This proportioner stands out for its versatility and reliability. It works with both water turbine and electric motor drives, offering flexible power setups for sites with or without stable grid access. The balanced pressure mechanism eliminates manual adjustments, ensuring consistent foam-water mixtures for solid combustibles (Class A), flammable liquids (Class B), and even electrical equipment fires (Class C) when paired with compatible foam types. Its heavy-duty construction withstands harsh industrial environments, including corrosive atmospheres and extreme temperatures, while standard DN100–DN300 flanged connections simplify integration into existing fire networks.
