Key features

SS316L Medical-Grade Surface: Electropolished interior finish prevents bacterial growth to ensure ultra-pure filtration for food, beverage, and pharmaceutical industries.

Quick-Swing Bolt Closure: Achieve filter element replacement in under 2 minutes to maximize production uptime without the need for specialized tools.

Zero-Leak Sealing Technology: Stop dealing with messy liquid bypass; our precision CNC-machined grooves and EPDM O-rings guarantee 100% airtight sealing even under fluctuating pressure.

Extreme Corrosion Resistance: Forget about rust and frequent housing replacements; our high-molybdenum SS316L construction thrives in harsh seawater and chemical environments.

30% Higher Flow Efficiency: Optimized internal fluid dynamics deliver 1.3x the throughput of standard housings, allowing you to use smaller, more cost-effective units for the same output.

1.5x Rated Burst Pressure: Every unit is factory-tested to 150 PSI (10 Bar) or higher, providing a 50% safety margin compared to standard industry requirements for peak operator safety.

Compact Modular Integration: The space-saving vertical design allows for seamless installation in tight RO skid systems or mobile water treatment units without sacrificing filtration capacity.

All-Weather Industrial Durability: From coastal desalination plants to remote chemical refineries, the rugged exterior finish resists salt spray and UV degradation for decades of reliable outdoor serv

Superior Alloy Composition: Contains 25% more Chromium and Nickel than leading competitors basic SS304 units, offering unmatched resistance to pitting and crevice corrosion.

Precision Mirror Polishing: Delivers a Ra<0.4um surface roughness-3x smoother than standard industrial housings-effectively eliminating dead zones where contaminants could accumulate.

AI-Powered supplier vetting

SummaryThe supplier operates in screen-mesh processing and manufacturing, luggage and bags, related equipment and accessory sales, and general import/export activities. It has documented procedures and records for corrective actions and complaint handling, quality assurance, finished-product inspection instructions, inventory capability, and valid manufacturing-capacity contracts with affiliated subcontractors. Customization is offered from samples and designs, including full, minor, and flexible customization, but no 3D software design service is provided, no new product was reported in the past year, and R&D audit documentation was unavailable. Production inspection is based on random inspection by two quality inspectors. The supplier has no overseas warehouse, showroom, agent, or branch, although it has participated in FiltXpo 2025. Financial credibility and customer-case strength cannot be determined from the provided information.

Supplier typeThe supplier’s stated scope covers screen-mesh processing and manufacturing, sales and technical services for screen meshes, mechanical equipment and accessories, rubber and plastic products, household items, luggage and bags, and import/export activities. This supports classification as a manufacturer and trading/service supplier rather than a narrowly specialized single-product entity.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaints, plus in-stock service capability. However, it lacks overseas warehouses, showrooms, agents, and branches; therefore, documented service-process capability is evident, but overseas service coverage is limited.

R&D capabilityThe supplier reports no new products in the past year and has no R&D design-input, output, review, verification, or validation documents available for audit. Although the general manager cooperates with the factory on customer-requested product development and AutoCAD is listed, the available evidence does not establish strong, documented innovation capability.

Production capacityProduction-related evidence includes two quality inspectors, random finished-product inspection, standardized inspection instructions that are uniformly followed, quality assurance in quality-control processes, inventory capability, and valid manufacturing-capacity contracts with affiliated subcontractors. These explicit controls support production capability, although the slices do not state production volume or capacity.

Customization capabilityThe supplier explicitly offers customization from samples and designs, full customization, minor customization, and flexible customization. The general manager is also described as cooperating with the factory to develop products according to customer requirements, while the absence of 3D software design service limits the available design-support format.

Product Q&A

Q:What is the main difference between SS304 and SS316L for filter housings?

SS304 is the standard choice for most water treatment and general industrial applications. However, SS316L contains Molybdenum, offering superior resistance to pitting and crevice corrosion, making it essential for high-chlorine environments, seawater desalination, and pharmaceutical processes.

Q:How do you ensure the safety and pressure rating of your housings?

Safety is our priority. Every housing undergoes a hydrostatic pressure test at 1.5x the design pressure before shipment (e.g., a 10 Bar unit is tested at 15 Bar). We use automatic robotic welding and CNC machining to ensure 100% penetration and structural integrity.

Q:Are your filter housings suitable for the Food & Beverage or Pharmaceutical industries?

Yes. We offer Sanitary Grade housings with internal mirror polishing (Ra < 0.4um). These units feature a "No Dead Zone" design to prevent bacterial growth and are equipped with FDA compliant EPDM or Silicone gaskets, meeting strict hygienic standards.

Q:Can you customize the inlet/outlet types and housing dimensions?

Absolutely. We provide flexible connection options including ANSI/DIN Flanges, NPT/G Threads, and Tri-clamps. As an OEM manufacturer, we can also customize the housing height, diameter, and leg support to fit your specific skid-mounted system or limited floor space.

Q:Which is better for my application: Bag Filter or Cartridge Filter?

Bag Filters are best for high-flow pre-filtration and removing bulk solids due to their large dirt-holding capacity and lower replacement cost. Cartridge Filters are preferred for "polishing" and high-precision filtration (down to 0.1um), ideal for final stages in beverage or electronic water systems.
