Foam Water Monitor

Foam water cannons are short for dual-purpose foam-water fire monitors. Their core function is to switch between spraying water or a foam mixture, enabling long-range extinguishing of Class B liquid fires (oil, chemicals) and Class A solid fires, while also providing cooling and fire isolation.

Core Definition and Key Differences

Positioning: A core product category in the fire monitor series, possessing both "water cannon cooling" and "foam cannon isolation" capabilities, distinguishing it from pure water cannons (spraying only water) and pure foam cannons (spraying only foam).

Key Parameters: Rated flow rate 24–100L/s, working pressure 0.4–1.2MPa, foam range ≥32m, water range ≥37m, horizontal rotation 360°, pitch -30°~+60°.

Working Principle and Structure

Principle: Pressurized water is mixed with foam liquid at a ratio of 3%/6% via a proportioner. The mixture is diffused and atomized through nozzles, drawing in air to generate air foam that covers the fire scene; switching to water path directly sprays water for cooling.

Structure: It consists of a base, gun body, rotating body, nozzle, control valve, and proportioning mixer. It has three control modes: manual, electric, and remote control. The rotating mechanism mostly adopts worm gear, which is self-locking and flexible.
