CAFS

As a complete functional module the LSA 3000 combines all components of a CAFS system in one assembly group. The Vehicle Mounted Pump, compressor, foam proportioning, the patented LSA mixing valve and all measuring and controlling components are mounted on the base frame. CAFS is produced independently from the Vehicle Mounted Pump without pressure loss and without limitations of water flow. Therefor compressed air is blown in the water/foam flow by a proportional pressure regulation valve into the mixing valve. The unit can also handle heavily changing operating conditions (e.g. during chopping) by its modern measurement and control system.
