8040 FRP (1) Element RO Membrane Housing Reverse Osmosis 8Inch 300PSI

Selecting the Right Codeline 80S Pressure Vessel

Choosing the correct pressure vessel is critical for system safety, membrane longevity, and ease of maintenance. Use these three key factors to find your match.

1. Pressure Rating: 300 PSI vs. 450 PSI

The pressure rating must exceed your system’s maximum operating pressure, especially during cold-water start-ups when pressure naturally spikes.

  • Choose 300 PSI (80S30 Series): For standard brackish water RO systems where operating pressures remain relatively low. These are the industry standard for most commercial and light industrial applications.

  • Choose 450 PSI (80S45 Series): For high-recovery systems, high-TDS water sources, or wastewater recycling. If your system requires higher pump pressure to overcome osmotic resistance, the 450 PSI series provides the necessary safety margin.

2. Element Capacity: How many 8040 membranes?

The “dash” number in the SKU (e.g., -1, -3, -6) indicates how many 8-inch membranes fit inside a single housing.

  • 1 to 2 Elements: Best for compact skids or low-flow applications.

  • 3 to 4 Elements: The “sweet spot” for most medium-to-large industrial RO systems.

  • 6 Elements: Ideal for high-volume plants where minimizing the number of housings and manifold connections is a priority.

3. Port Size & Flow Rates

The side-port size determines how much water can enter or exit the vessel without causing a significant pressure drop.

  • 1.5″ IPS Grooved (Standard): Ideal for single-vessel setups or systems with moderate flow rates.

  • 2.0″ IPS Grooved (High-Flow): Recommended for 4-to-6 element vessels or systems where multiple vessels are manifolded together. This larger port size reduces friction and improves energy efficiency.
