2540 SS RO Housing – 300 PSI Stainless Steel Vessel
The 2540 SS RO Housing is a heavy‑duty pressure vessel designed for reverse osmosis and similar membrane systems where strength and reliability matter most. This stainless steel housing supports a 2.5″ × 40″ (2540) membrane and withstands operating pressures up to 300 PSI, making it ideal for demanding water purification tasks in commercial, industrial, and large residential settings.
Because this vessel uses strong stainless steel construction, it delivers excellent corrosion resistance and mechanical strength. At the same time, the polished metal finish makes it suitable for sanitary applications in food, beverage, or pharmaceutical systems where clean surfaces are preferred.
Technical Specifications
To help you pick the right housing, here are the main details:
| Specification | Detail |
|---|---|
| Membrane Size | 2.5″ × 40″ (2540) |
| Max Working Pressure | 300 PSI (21 bar) |
| Housing Material | SS304 or SS316L stainless steel |
| Surface Finish | Polished/sanitary |
| Port Options | BSP, NPT, tri‑clamp, Victaulic, or flanged |
| Typical Use Temp Range | Industrial range (varies by configuration) |
These specs make the 2540 SS RO Housing a flexible choice for systems that demand long service life and reliable high‑pressure operation.
How It Works in RO Systems
In a high‑pressure RO setup, feed water enters the housing and flows along the membrane surface. First, high pressure pushes the water through the membrane. Then, the filtered, purified water – called permeate – exits through the center outlet, while waste or concentrate exits through the side port. Therefore, this SS RO vessel forms the backbone of systems designed to produce clean water consistently and efficiently.
Benefits of Stainless Steel Construction
A stainless steel membrane housing offers several clear benefits:
- High pressure tolerance: It handles up to 300 PSI for demanding purification work.
- Excellent corrosion resistance: SS304/SS316L stands up to tough environments better than many alternatives.
- Flexible connection options: Choose from BSP, NPT, tri‑clamp, Victaulic, or flange types to match your plumbing layout.
- Sanitary surface: Polished finish helps maintain water quality and ease of cleaning.
Ideal Applications
This housing works well in:
- Industrial water treatment systems
- Commercial RO installations
- Food & beverage processing lines
- Laboratory and pharmaceutical setups
- Mining and wastewater treatment
Installation Tips
Install the vessel on a solid support frame, and then select fittings that match your piping. Also, inspect O‑rings and seals when you install or replace membranes to prevent leaks. Regular flushing and sanitation help maintain water quality and long life.
