PVC Membrane Housing Pressure Vessels for RO Systems
4x80 PVC Membrane Housing Pressure Vessel for RO Membranes

For Housing Two (2) 4x40 Membrane Elements

AMI PVC pressure vessels for housing double 4" x 40" membrane elements are ideal for lower pressure membrane applications up to 200 PSI are designed for direct connection to AMI/Applied Membranes and FILMTEC/DOW style elements. The U-Pin style end closures are designed for ease of installing and replacing membrane elements, and the ½" FNPT connections for ease of connection with no special fittings required. Each membrane housing is individually inspected for quality assurance.

Each membrane housing is sold complete with End Plugs, U-Pins, Feed Plugs, and O-Rings.  Mounting pads and straps are sold separately.

Warning:  4x80 PVC pressure vessels are limited to a maximum pressure of 200 psi (14 BAR) at 77°F (25°C).  Higher pressure, higher temperature or water hammer will lead to premature failure.  It is highly recommended that when these conditions exist, a pressure switch or relief valve be installed to protect the vessel.  Alternatively, you may consider a stainless steel or FRP vessel.
