Housing Membrane Stainless Steel 10.000 GPD Stainless steel ( SS) membrane housings are commonly used for sanitary or high temperature applications where fiber reinforced plastic ( FRP) is unsuitable. Unlike FRP, SS is not degraded by UV rays in sunlight and so more suitable for outdoor environments, potentially eliminating the costly requirement for a building. The vessels are available with end or side port configurations, and Nylon or SS end caps. Technical Information Diameter - 8 " Length - 1-3 elements Pressure - 20 bar ( 300 psi)
