Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998, specializing in high-performance filtration solutions. Our Precision Filtration Unit 316L SS 400 Bar Working Pressure Sanitary Clamp Connection is engineered to meet the most demanding industrial standards, combining robust construction with hygienic design. This unit is ideal for applications requiring ultra-high pressure filtration, such as pharmaceutical processing, biotechnology, and food & beverage production, where product purity and equipment reliability are critical.
Built from premium 316L stainless steel, this filtration unit offers exceptional corrosion resistance and long service life even under extreme conditions. The 400 bar working pressure capability ensures safe operation in high-pressure systems, while the sanitary clamp connection provides quick, tool-free disassembly for easy cleaning and maintenance. Each unit is precision-machined and polished to a surface finish of Ra ≤ 0.4 μm, reducing bacterial adhesion and meeting cGMP requirements.
Below we detail the key features, technical specifications, and benefits that make our filtration unit an excellent choice for your process.
Key Features & Benefits
- High-Grade Material: 316L SS (1.4404) offers superior resistance to pitting and crevice corrosion, ideal for CIP/SIP cycles.
- Ultra-High Pressure Rating: Rated up to 400 bar (5800 PSI), suitable for reverse osmosis, high-pressure injection, and hydraulic systems.
- Sanitary Design: Clamp connection with Tri-Clamp standard (ISO 2852) ensures leak-free seals and easy sterilization.
- Customizable Filtration: Accepts pleated filter cartridges, mesh elements, or sintered wire mesh with micron ratings from 0.5 to 100 μm.
- Low Pressure Drop: Optimized flow path minimizes energy loss while maintaining high dirt-holding capacity.
- Full Traceability: Each unit comes with material test certificates (MTC) and hydrostatic test reports.

Detailed Product Description
Our precision filtration unit is designed for applications where product purity and system reliability are paramount. The 316L stainless steel body is forged and machined to withstand pressures up to 400 bar, making it one of the most robust filters in its class. The sanitary clamp connection complies with international standards (3A, ASME BPE) and allows quick changeover of filter elements without tools, reducing downtime during production.
The unit is available in multiple sizes, with inlet/outlet diameters from 1 inch to 6 inches, and can be customized to fit your existing piping. The internal design minimizes dead zones, ensuring complete drainage and preventing product contamination. For high-viscosity fluids, an optional heating jacket can be integrated.
Each filter is rigorously tested before shipment: a hydrostatic pressure test at 1.5 times the working pressure is performed, and a bubble point test for filter integrity is available upon request. We also offer 3.1 material certificates and NACE MR0175 compliance for sour service environments (optional).

Frequently Asked Questions (FAQ)
-
Q: What is the maximum operating pressure of this filter unit?
A: The unit is rated for 400 bar (5800 PSI) working pressure. A hydrostatic test at 600 bar is performed on each unit before shipment. -
Q: Can the filter element be changed without removing the housing?
A: Yes, the sanitary clamp design allows quick access to the filter element. Simply loosen the clamp and lift the top cover (or remove the cartridge) for replacement. -
Q: What micron ratings are available?
A: We offer ratings from 0.5 μm (absolute) up to 100 μm, using pleated cartridges, mesh, or sintered wire mesh. Custom micron sizes are available upon request. -
Q: Is this unit suitable for CIP (Clean-in-Place) systems?
A: Absolutely. The 316L SS construction and Ra ≤ 0.4 μm surface finish make it fully compatible with CIP and SIP procedures. Optional electropolishing further enhances cleanability. -
Q: What gasket materials do you recommend?
A: Standard gasket is EPDM (suitable for water and many chemicals). For high-temperature applications, we recommend Silicone or Viton. Please specify your fluid and temperature range. -
Q: Do you provide custom sizes or special connections?
A: Yes, we can customize the unit dimensions, inlet/outlet types (e.g., flanged, threaded, or welded), and internal volume. Minimum order quantity may apply. -
Q: How long is the lead time for standard units?
A: For standard sizes (1.5″ to 4″), lead time is typically 15-20 working days. Custom orders may require 25-30 days depending on complexity. -
Q: Do you offer certificates of material or pressure test reports?
A: Yes, we provide 3.1 material certificates and hydrostatic test reports upon request. Additional certifications (e.g., NACE, PED) can be arranged at an extra cost.
