AquaTeam is a high-volume water purification device designed for group use. It is ideal for family camping, military purposes, disaster relief, or remote areas where running water is unavailable. The shape and structure of AquaTeam are designed to require the minimum application of muscle force. Pumping clean water out of AquaTeam requires roughly the same effort as pumping air into bike tires yet the water volume per stroke is at least 20 times more than that of hand-held devices. The water tank provides a great reservoir to store clean water.
