2.5” End Clamp SS
ART Stainless Steel Pressure Vessel Membrane Housings are designed for use in commercial reverse osmosis, nanofiltration, and ultrafiltration water treatment systems. The seamless stainless steel body is sturdy and reliable, while giving a smooth, sleek look to the system. The unique clamp-on end closures provide easier removal of the end caps for faster maintenance and membrane change-outs.
ART 2.5" SS Membrane Housings are designed for direct connection to ART/All Refine and FilmTec/DOW style 25x14, 25x21, or 25x40 membrane elements. Lighter, safer, and more reliable than PVC membrane pressure vessels, our stainless steel membrane housings will not be affected by UV rays or sunlight, and are ideal for system pressures up to 250 PSI.
