4 x 21 PVC Membrane Housing Pressure Vessel for RO Membranes

AMI PVC pressure vessels for housing 4" x 21" membrane elements are ideal for lower pressure membrane applications up to 200 PSI and 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.

PVC Membrane Housing Specifications

Warning: 4x21 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.
