4" x 40" Spot Free Rinse Car Wash RO Membrane (2,600 GPD)

This professional-grade, extra low energy reverse osmosis (RO) membrane is purpose-built for commercial car wash operations and high-volume spot-free rinse systems. Designed to drop seamlessly into standard 4-inch by 40-inch commercial pressure vessels, this element provides operators of tunnel washes, in-bay automatics, and self-serve bays with a high-yield water purification solution that significantly cuts energy consumption and utility overhead.

Engineered with advanced thin-film composite (TFC) technology, this heavy-duty membrane achieves peak efficiency at an extra-low applied test pressure of just 100 PSI. Under these optimized operating conditions, it delivers a high-capacity nominal permeate flow rate of 2,600 gallons per day (GPD) while maintaining an exceptional salt rejection rate of 99.20%. By effectively stripping the feed water of the total dissolved solids (TDS) that cause mineral spotting, this membrane guarantees a flawless, spot-free vehicle finish while minimizing the mechanical strain on your pump room equipment.
