Stainless Steel RO Membrane Housing – 4″ End Entry Series (300 PSI)

Premium <strong>Stainless Steel RO Membrane Housing</strong> designed for commercial 4040 reverse osmosis elements. Constructed from heavy-duty SUS304 or 316L, this housing features a reliable end-entry clamp closure system and is rated for 300 PSI, making it the industry standard for durable, sanitary water purification systems.

Descripción del producto

The Hygienic Choice for Commercial Filtration.

The Stark 4-inch Stainless Steel Membrane Housing is the robust protective shell for your valuable reverse osmosis elements. Unlike PVC housings that can degrade under UV light or FRP housings that may not meet strict sanitary requirements, our stainless steel vessels offer superior corrosion resistance, UV stability, and structural strength.

Featuring a polished exterior and a seamless body option, these housings are specifically engineered for applications requiring high hygiene standards, such as food & beverage production, pharmaceutical water, and premium spot-free rinse systems.

Material Certification:
Ensuring the authenticity of 304/316L stainless steel is critical for corrosion resistance. For raw material Mill Certificates, hydrostatic pressure test reports (1.5x safety factor), and detailed dimensional drawings, please reference the technical data at our manufacturing division:

Industria aplicable

  • Food & Beverage Production:
    Stainless steel construction meets sanitary requirements for bottled water and beverage processing (unlike fiberglass).
  • Commercial Kitchens:
    Ideal for restaurants and coffee shops where compact, hygienic filtration systems are visible and must meet health codes.
  • Biotech & Medical:
    Perfect for laboratory water systems where zero light penetration is critical to prevent algae growth inside the housing.

Ventaja Uno

Superior Corrosion Resistance & Hygiene

Stark Stainless Steel RO Membrane Housings are built to last. Made from high-grade SUS304 or SUS316L, they are impervious to UV radiation, temperature fluctuations, and environmental corrosion. Compared to PVC housings which can become brittle over time, our stainless steel vessels maintain their 300 PSI pressure rating for decades, providing a safe and reliable enclosure for high-pressure RO processes.

Ventaja DOS

Quick-Release Clamp Design

Maintenance efficiency is key for system operators. Our “End Entry” design features a heavy-duty stainless steel clamp closure system that allows for tool-free opening. This enables technicians to replace 4040 membrane elements in minutes rather than hours, significantly reducing downtime during routine maintenance.
