A group on the move needs a water source it can count on. As indestructible as it gets, the Expedition is as easy to use as it is to pack along.\n\nThe tried and tested ceramic depth filter removes bacteria, protozoa and other disease-causing agents. The microorganisms cannot pass through the mini pores of the filter ceramic (0.2 microns) because of their size (greater than 0.2 microns = 0.0002 mm). \n\nThe output is approx 4L/min., which makes it ideal for groups requiring large amounts of water. The capacity is up to 100'000L, depending on the water quality. \n\nIdeal for rafting operators, relief organizations, army troops as well as for travels by motorhome or car.
