Rainman Frame AC 100L, manual
What you are actually buying
Drawn to this model’s own published specification: framed, 3 × 21in membranes, and a pump driven by an AC 240V motor.
What it costs to run
A four-person crew using 25 litres a head needs 100 litres a day. On this system that is:
This is an AC system, so it needs a generator, shore power or a large inverter. The Wh figure is what the generator has to cover.
Is it worth it?
At 13.9 watt-hours per litre this is one of the thirstier systems we rank — 3.8 times the energy of the most efficient, for the same litre. 1,389 Wh a day for a crew of four is an engine run, not a solar surplus.
Suits
Look elsewhere if
- Boats without a generator or a large inverter. 1,250 W on 240 V is not something a modest inverter starts happily.
- Boats you cannot drill. This is an installed system: intake, seacock, brine discharge and a wiring run, quoted separately from the unit.
Worth pricing against it: Schenker Zen 100 makes 100 litres an hour at 4.0 Wh/L, so the same 100 litres costs 989 Wh less every day — for $958 more up front. See the Zen 100 →

Where it sits in the market
Ranked 29 of 34 rated systems on watt-hours per litre, where lower is better.
A conventional high-pressure pump with limited membrane area, so each litre costs comparatively more energy. Fine on a generator, expensive on a battery bank. How the two technologies differ →

Common questions
- How much power does the Rainman Frame AC 100L, manual use?
- It draws 1,250 W and makes 70–110 L/hr, which works out to 13.9 watt-hours per litre. Making 100 litres — four people at 25 litres a head — costs about 1,389 Wh.
- How long does the Frame AC 100L, manual take to make a day's water?
- At its rated 70–110 L/hr, 100 litres takes about 1.1 hours. Output falls in cold or silty water, so treat that as a best case rather than a promise for every anchorage.
- How much does the Rainman Frame AC 100L, manual cost in Australia?
- Our indicative figure is $8,642, taken from the manufacturer's published US list and excluding freight, duty and installation. Australian dealer pricing is usually all-inclusive and reads higher. Ask a stockist for a landed AUD quote before you budget.

- Is the Frame AC 100L, manual efficient?
- It ranks 29 of 34 rated systems in our table on watt-hours per litre, where lower is better. The best in the table is 3.7 Wh/L. It uses a conventional high-pressure pump, which is the main reason it sits above the energy-recovery systems.
- Is the Rainman Frame AC 100L, manual worth it?
- At 13.9 watt-hours per litre this is one of the thirstier systems we rank — 3.8 times the energy of the most efficient, for the same litre. 1,389 Wh a day for a crew of four is an engine run, not a solar surplus.
