ART 2.5” End Port FRP
1200 PSI End Port Seawater Membrane Housing Pressure Vessels
ART fiberglass membrane housings are rated at 1,200 psi and specially designed for seawater reverse osmosis membranes used in marine applications. Commonly used in watermakers, ART FRP seawater pressure vessels are suitable for seawater desalination in shipboard applications, watermakers, land-based desalinators and sea-based desalinators.
ART FRP seawater RO membrane housing end caps are designed for direct connection to Industry Standard Style 2.5" diameter male style elements (such as All Refine, Inc. ART Membranes, and FilmTec style membranes).
