Proportioners For Fire Trucks
FireDos proportioners for fire trucks are developed for municipal, volunteer and industrial fire brigades — purely mechanical, operating independently of any on-board power supply.
FireDos Proportioners for Fire Trucks
FireDos proportioners for fire trucks are developed specifically for municipal, volunteer and industrial fire brigades. Purely mechanical in design, they operate independently of any on-board power supply — driven solely by the flow of extinguishing water. Easy to operate, reliable and flexible, they fit into crew cab fire trucks, tanker vehicles, roll-off containers and aerial ladder trucks.
Key Advantages
• Purely mechanical — no external power supply required • Constant proportioning rate under all operating conditions • Ready to use after one-time venting — no delays in emergency • Suitable for all foam agent types including high-viscosity fluorine-free agents • Compatible with all nozzle and discharge device types • Stepless proportioning rate adjustment during operation • Suitable for pulsating and intermittent operation

Proportioner Series for Fire Trucks
Series | Water Flow Rate | Proportioning Rates FZ1000 | 60 – 1,000 l/min | 0.1 / 0.3 / 1 / 3 % (stepwise) FZ2000 | 100 – 2,000 l/min | 0.1 / 0.3 / 1 / 3 % (stepwise) FD2000 | 200 – 2,000 l/min | 0.3 – 3 % (stepless) FD3000 | 250 – 3,000 l/min | 0.3 – 3 % (stepless) or 3 / 6 % (fixed) FD4000 | 500 – 4,000 l/min | 3 / 6 % (fixed)
Suitable for All Fire Truck Types
Crew Cab Fire Trucks
FireDos proportioners fit perfectly into crew cab fire trucks of different sizes. Four flow directions through the water motor guarantee flexible installation — including retrofitting into existing vehicles.
Industrial and Tanker Fire Trucks
Tanker fire trucks provide more space for larger proportioner sizes, enabling higher water flow rates for demanding industrial firefighting operations.
Roll-off Containers
The largest proportioner sizes are installed in roll-off containers — serving as emergency units or bridging mobile water supply over longer distances.
Other Vehicles
FireDos proportioners also fit aerial ladder platforms, fire trailers and wildfire firefighting aircraft.
