Outdoor Survival Pump
Pumps exist because a group needs more water than a straw can deliver. Four models cover that range, all at 0.01 micron through a hollow fiber membrane.
O-C2 is the baseline at 250 g and 2000 L. O-C3 is the fast one — 700–1000 ml/min and 3000 L at 185 g. O-C4 is the pocket unit at 170 g with a stainless mesh stage for gritty water. O-C5 is the station: 304 stainless steel and ceramic membrane, 10000 L and 4 L/min at 2.8 kg.
The lighter pumps add KDF and carbon fiber for heavy metals and odour; the stainless station adds ceramic and copper-zinc media for repeated group use.
