Leader MIX 50–275 GPM Portable Foam Inductor

Leader MIX 50–275 GPM Portable Automatic Foam Proportioner

The LeaderMIX 50–275 GPM Portable Automatic Foam Proportioner is a fully autonomous, mechanical foam dosing system designed to deliver accurate and consistent foam concentrate proportions across a wide range of flow rates. Developed for firefighting, industrial fire protection, and emergency response operations, this portable proportioner operates without electricity or external power, ensuring dependable performance in demanding field conditions.

Engineered for simplicity and reliability, the LeaderMIX system automatically adjusts to pressure and flow variations while maintaining precise foam concentration, making it well suited for dynamic firefighting environments where conditions can change rapidly.

Operational Overview

The LeaderMIX Portable Automatic Foam Proportioner utilizes a self-powered mechanical proportioning system that inducts foam concentrate into the water stream based on flow rate. Operating from approximately 50 to 275 GPM, the unit maintains accurate foam dosing even when pressure or flow fluctuates during operations.

The system begins operating at approximately 75 psi and responds instantly to changes without requiring calibration, electronics, or external controls. This autonomous operation reduces setup time, minimizes maintenance requirements, and improves reliability during emergency response scenarios.

Construction

Designed for professional fireground and industrial use, the LeaderMIX features a robust mechanical design housed in a durable, compact enclosure suitable for transport and rapid deployment. The portable configuration allows the unit to be connected directly to apparatus discharge outlets, portable manifolds, or ground-based hose layouts.

The absence of electronic components enhances durability and reduces failure points, making the LeaderMIX particularly suitable for harsh environments and long-term service.
