Hydranautics CPA5-LD-4040 Membrane

Quality parts at an exceptional value
Product Description

CPA (Composite Polyamide) elements set the standard for RO membrane elements – over 600 million gallons per day of pure water are produced by CPA elements for global municipalities and industries. 4” and 8” configurations available.

CPA5-LD has minimized biofouling, minimized colloidal fouling and enhanced cleanability. When high performance counts, CPA membranes from Hydranautics set the standard for RO membrane elements. CPA membranes provide the highest salt rejection rates available - every element on every order for every customer.
