This trolley turns ordinary tap water into pure water on site, so a waterfed pole leaves glass and frames to dry without spots. It is built for commercial work: one municipal water outlet can feed two waterfed poles at the same time.
Built to order: please allow a 7 day build period before dispatch.

Why the 4040 membrane matters
Reverse osmosis forces water through a membrane that holds back dissolved salts and minerals. Those minerals are what leave white spots when tap water dries on glass or on solar panels. A 4040 membrane has a far larger surface than the small membranes in compact units, which is how this trolley reaches 6 litres a minute. For comparison, a 75 GPD membrane makes about 12 litres an hour.
Who it suits
Teams that clean windows or solar panels all day and cannot wait for a holding tank to fill. If you work alone with one pole, the smaller 75 GPD reverse osmosis system or the deionised water supply may be enough. Check your output water with a TDS meter.
