1INTRODUCTION
The Leader MIX CLASSE B/AR & CLASSE A 200-1000 l/min (50-275 gpm) is a variable flow dosing system which
can be used to inject foam concentrate into a pressurised water network.
There is a remote console for the Fixed model.
The Leader MIX CLASSE B/AR & CLASSE A 200-1000 l/min (50-275 gpm) automatically adapts to the network flow.
The Portable model is equipped with a pressure meter and a suction indicator.
The Fixed model is equipped with a remote console.
It works similarly to in-line venturi injectors, it replaces 3 traditional injectors: 200, 400 and 800 L/min (50, 100 and 200 gpm).
It does not require a power supply or specific maintenance (just rinse and purge the system after use).
There are 2 models: Portable or Fixed.
