Description
The First Line 4040 × 2 Element FRP Same Side Port Membrane Housing is a premium-quality fiberglass reinforced plastic (FRP) pressure vessel designed to accommodate two standard 4″ × 40″ reverse osmosis membranes in a single housing. Engineered for commercial and industrial water treatment systems, it provides reliable performance, efficient water flow, and a compact installation solution.
The same side port configuration positions the feed and concentrate connections on the same end of the vessel, simplifying pipework and making it particularly suitable for compact RO system layouts. Manufactured from high-strength FRP composite materials, the housing offers excellent resistance to corrosion, chemicals, UV exposure, and high operating pressures.
Compatible with most standard 4040 RO membranes, the First Line 4040 × 2 Element FRP Same Side Port Membrane Housing is an excellent choice for medium- to high-capacity reverse osmosis systems where space efficiency, easy maintenance, and long-term reliability are important.
