Leader MIX AR 50–275 GPM Vehicle Mounted Automatic Foam Inductor

Leader MIX AR – Vehicle Mounted Automatic Foam Proportioning System (50–275 GPM)

The Leader MIX AR Vehicle Mounted Automatic Foam Proportioning System is a fully autonomous mechanical foam dosing system designed for fire apparatus and fixed foam installations. Built around trusted 100 % mechanical proportioning technology, this system provides reliable and accurate induction of foam concentrate into the water stream across a wide range of flow conditions without requiring an external power source.

Operational Overview

The Leader MIX AR system uses a simple yet robust mechanical venturi-based automatic dosing design — a method widely recognized in the fire service as a practical compromise between traditional venturi foam eductors and complex electronic dosing systems. These systems adapt instantly to flow variations, maintain consistent foam concentrate ratios, and require minimal maintenance due to their lack of electronics or power components.

Installed directly onto a vehicle’s foam plumbing or fixed foam system, the Leader MIX AR is intended for frequent use by municipal fire departments, industrial fire brigades, and other professional response teams that value durability, reliability, and simplicity.

Features

Based on independent sources describing Leader automatic foam proportioners:

• Automatic and autonomous mechanical dosing: Adjusts foam induction based on flow without electronics or power.

• Wide flow adaptability: Designed to provide accurate foam proportioning throughout the 50–275 GPM operating range.

• Durable, simple design: Requires minimal maintenance compared to electronic dosing systems.

• Integrated control panel: Mounted configuration allows easy operation directly from vehicle or fixed installation.

• Professional-grade performance: Suitable for Class A, Class B, and AR foam concentrates in demanding fire response conditions.

How It Works

Leader’s automatic foam proportioners operate by creating a controlled venturi effect that draws foam concentrate into the water stream proportional to the flow rate. Because the system adjusts mechanically, it keeps foam concentrations within desired settings even as water pressure and flow change — a key advantage in dynamic fireground environments.

This mechanical method has been widely adopted in modern fire apparatus because it provides reliable and repeatable foam dosing without the complexity and maintenance challenges of electronic metering systems.

Applications

The Leader MIX AR Vehicle Mounted Automatic Foam Proportioner is ideal for:

• Fire apparatus foam delivery systems

• Fixed or semi-fixed foam suppression installations

• High-demand structural firefighting scenarios

• Industrial facility fire response teams

• Municipal and mutual-aid departments

Available Configuration

Notes

The Leader MIX AR system is based on proven mechanical proportioning principles that require no external electrical power. System performance is consistent across its rated flow range and adaptable to a wide variety of foam concentrates.
