Over the years, Al-Adil Auto has developed the patented FHP foam mixing system which allows mixing foams (or other filming agents, depending on the use) with different mixing percentages, depending on which foam is used, independently by the circuit load (defined by the flow and pressure values inside the circuit).

This system can overcome the problems of typical Venturi mixing systems, like the length of the hose: the FHP system allows the operator to obtain the best performances even with 200 m of hose, while maintaining the correct mixing percentage between water and foam. A special nozzle, able to operate either with water or with water/foam, allows the correct mixture delivery. An optional proportional viewer is available which allows the operator to see the foam mixing percentage while using the FHP system (the values shown varies depending by the foam type used).
