Foam proportioner

Automatic and autonomous

Autonomous, it requires no power supply to operate. The foam eductor LeaderMIX can operate simultaneously with multiple nozzles of variable flow rates.

Wide operating range 200-1050 l/min

The foam proportioner LeaderMIX has a wide flow rate range (200-1050 l/min) and advantageously replaces up to 3 conventional inductors (200, 400 and 800).

Sucked in for sure!

Foam concentrate is instantly sucked in by LeaderMIX even during pulsing. LeaderMIX operates from 5 bar up, adapts to flow rate variations and does not generate more pressure drop than a conventional venturi.

Portable and compact

LeaderMIX 200-1000, in its portable version, weighs less than 14 kg and fits easily in the trunk of a vehicle. It can be used on the ground in line by firefighters or directly from the supply manifold outlet.
Product features
Technical sheet


Perfect compromise between the conventional venturi proportioner and the electronic foam dosing system, LeaderMIX 200 - 1000 allows precise dosing of all types of foam concentrates even during high flow rate variations. Starting at 5 bar, it allows the accurate dosing of the foam concentrate from 0.3% to 6% over a flow rate range from 200 to 1050 l/min.

Automatic, autonomous and requiring almost no maintenance, it is very easy to use and has a bypass position that reduces pressure drops when the use of additive is not necessary.
