2.8 gallon max. capacity depending on water pressure
Approx. Size: (diameter: 9 inches; height: 13.5 inches)

Output / Production:    

Testing by NSF International according to NSF/ANSI Standard 58 yielded 15.04 gallons per day with source water test parameters of 50 PSI pressure input, water temperature of 77F, pH of 7.5 +/- 0.5, and 750 ppm total dissolved solids (TDS). Higher production rates are expected with lower TDS levels. Lower production rates can be expected at colder incoming water temperatures.



The RO-2550 system uses a process of crossflow to constantly clean the membrane to prevent pre-mature fouling and clogging.
