Notes: Maximum production based on a feed water of 77°F, SDI < 1, 1000 ppm TDS, and pH 7. Individual membrane productivity may vary (± 15%). May be
operated on other feed waters with reduced capacity. Percent Rejection is based on membrane manufacturer’s specifications; overall system percent rejec-
tion may be less. *R4X40-3-230 is available only in 230-volt single phase.
