4" x 21" Spot-Free Car Wash RO Membrane (1,000 GPD)
Engineered specifically for commercial spot-free car wash systems that utilize standard 4021-sized pressure vessels, this high-performance reverse osmosis membrane delivers exceptional water purity. Proudly manufactured in the United States by Hydrocomponents & Technologies Inc. (HCTI), this industrial-grade, extra low pressure (XLP) element utilizes advanced thin-film composite technology. By operating effectively at a reduced feed pressure of just 100 PSI, it drastically minimizes the energy consumption and wear on your high-pressure booster pumps, making it a highly cost-effective solution for high-volume car wash operators.
This American-made element is built for continuous, rigorous wash cycles, delivering a robust nominal permeate flow rate of 1,000 gallons per day (GPD). With a stabilized salt rejection rate of 99.00%, it strictly removes total dissolved solids (TDS) and hard water minerals, guaranteeing a flawless, spot-free rinse every time. Whether integrated into an automatic rollover bay or a multi-wand self-serve car wash, this 4-inch by 21-inch membrane maintains consistent, ultra-pure water output to eliminate hard water spots, reduce drying times, and improve the final vehicle finish quality.
