4040 RO Housing – Durable FRP Membrane Vessel
The 4040 RO housing is a strong FRP vessel designed to hold two standard 4040 reverse osmosis membranes. It works well in commercial, industrial, and high-capacity residential RO systems. Moreover, it handles pressures up to 300 PSI, protecting the membranes from corrosion and wear.
How the RO Vessel Works
Water enters the RO housing under pressure and flows through the internal membranes. First, the pressure pushes water against the membranes. Then, the membranes filter out impurities, producing clean water. Because the housing uses water pressure, it does not require electricity. Therefore, you can install it in homes, offices, factories, or laboratories without extra equipment.

Key Benefits
Using this RO vessel increases system capacity and ensures reliable filtration. In addition, its strong FRP body resists rust and physical damage. Furthermore, the lightweight design makes installation and maintenance easier. You can also replace individual membranes without stopping the system, which saves time and keeps your water clean consistently.
Installation and Maintenance
Mount the vessel on a stable frame and attach the inlet and outlet connections securely. Check O-rings during membrane replacements. Also, follow the manufacturer’s schedule for changing membranes. By following these steps, your RO system will deliver clean water efficiently and reliably.
