What this video covers

The Rainman portable water maker system operates as a modular, non-proprietary desalination unit capable of producing approximately 36 to 37 gallons of fresh water per hour in its high-output configuration.1:10 The system consists of a pressure supply unit (PSU) containing a pump, motor, and 5-micron sediment pre-filter, and a separate membrane assembly.4:52 Setup requires connecting a high-pressure hose between the two components, dropping a raw water intake hose into the ocean, and plugging the unit into a 110V, 230V, or 12V power source.9:31 An integrated pressure gauge and valve allow the user to adjust flow rates, while a removable flow gauge monitors output.1:43 The system requires no lift pump, as an impeller built into the motor drive shaft draws water.10:12 Maintenance involves a simple freshwater flush using a 5-gallon bucket to prevent biological growth, or a sodium metabisulfate pickling solution for long-term storage.12:42 All components, including membranes and filters, are non-proprietary and available through standard retail channels.7:02
