The EMACO Portable Inline Inductor is a highly efficient foam proportioning device used in mobile firefighting operations where fixed proportioning systems are not available. Designed for direct connection between a fire hose and nozzle, it uses venturi suction to draw foam concentrate into the water stream at a controlled rate.
Built with corrosion-resistant materials and engineered to deliver accurate foam mixing even under varying pressure conditions, the unit is FM Approved and compatible with a wide range of foam concentrates, including AFFF and AR-AFFF types.
Compact, portable, and easy to operate, the EMACO Portable Inline Inductor is ideal for fire brigades, fuel handling areas, chemical processing zones, airports, offshore platforms, and industrial facilities where mobility and quick action are essential.
Key Features
The Portable Inline Inductor is a vital tool for emergency foam firefighting operations. Unlike fixed proportioning systems, which are installed permanently, the inductor is designed for field use—allowing firefighters to apply foam from any water source such as hydrants, pumps, or tankers.
Using a venturi principle, the device creates a pressure drop inside the water flow, drawing foam concentrate from an adjacent container and mixing it directly into the hose line. This makes it invaluable for operations involving flammable liquids, spill fires, aviation fuel incidents, and industrial hazards.
The EMACO Portable Inline Inductor is engineered for easy handling, reliability, and precise foam induction, ensuring that firefighters receive the correct foam concentration needed for effective fire suppression.
Connection to the Hose Line
The inductor is installed between the water supply hose and the foam nozzle. As water flows through the unit, a venturi chamber creates a suction effect.
Venturi Suction Operation
The pressure drop inside the chamber draws foam concentrate through a pickup tube connected to a foam drum or container.
Foam Proportioning Control
A metering valve regulates the foam concentrate flow to maintain the desired proportion—typically 3% or 6%.
Mixing and Discharge
The foam concentrate mixes with the water inside the hose line and exits through the nozzle as finished foam solution.
Pressure and Flow Stability
The unit is designed to operate within a specific optimal pressure range. When the correct inlet pressure is maintained, foam induction remains consistent and reliable throughout operation.
