Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with an annual export value of US$5-10 million, serving global markets including North America, Europe, Asia, and the Middle East. Our PTFE Sealed Pd/C Catalyst Filter Cartridge Housing 304SS for High Purity Application is engineered to deliver exceptional performance in critical catalyst filtration processes. This housing combines robust 304 stainless steel construction with advanced PTFE sealing technology, ensuring zero leakage, corrosion resistance, and high purity retention – making it the ideal choice for pharmaceutical, chemical, and petrochemical industries where catalyst recovery and product purity are paramount.
Our product is designed to accommodate standard filter cartridges (10", 20", 30") and can be customized to meet specific process requirements. The PTFE seal provides a reliable barrier against aggressive chemicals and high temperatures, while the 304SS body offers durability and long service life. Below is a detailed overview of its features, specifications, and benefits.
Product Features & Benefits
- PTFE Sealing Technology: Ensures leak-proof operation even under high pressure and temperature fluctuations. PTFE is chemically inert, making it suitable for harsh solvents and acidic environments.
- 304 Stainless Steel Construction: Offers excellent corrosion resistance, mechanical strength, and hygiene. The material is compliant with FDA and food-grade standards (optional).
- High Purity Application: Designed for catalyst filtration (e.g., Pd/C, Pt/C, Raney Nickel) where product purity is critical. The housing minimizes dead zones and prevents particle bypass.
- Customizable Design: Available with flange or tri-clamp connections, different inlet/outlet sizes, and optional heating jacket or pressure gauge ports.
- Easy Maintenance: Quick-open closure (e.g., swing bolt or clamp) for fast cartridge replacement. The smooth internal surface reduces cleaning time.
- High Flow Capacity: Optimized flow path reduces pressure drop and maximizes filtration efficiency.

This filter housing is specifically designed for high-purity catalyst filtration, such as Pd/C (palladium on carbon) recovery, where even minimal contamination can affect product quality. The PTFE seal ensures that no elastomeric particles leach into the process stream, maintaining the highest level of purity. The 304SS body can be passivated or electropolished to further enhance corrosion resistance and cleanability.
Why Choose Our Filter Housing?
- Proven Manufacturing Expertise: With over 25 years of experience in wire mesh and filtration products, we understand the demands of catalyst filtration. Our factory in Hengshui, Hebei, China, is equipped with advanced CNC machining and welding facilities.
- Strict Quality Control: Each housing undergoes hydrostatic pressure test (1.5x design pressure), surface roughness inspection, and dimensional verification before shipment.
- Flexible Customization: We offer custom inlet/outlet sizes, additional ports (e.g., for pressure gauge, vent, drain), and special coatings upon request.
- Global Logistics: Ship from Tianjin, Qingdao, Shanghai, or Foshan ports. We have shipped to over 50 countries with reliable delivery times.
Frequently Asked Questions (FAQ)
- Q: What is the typical pressure drop across this filter housing? A: The pressure drop depends on the flow rate, viscosity, and cartridge type. For a clean 10" cartridge at 10 m³/h water, approximate pressure drop is 0.2 bar. We can provide calculations based on your process conditions.
- Q: Can this housing be used for hydrogenation reactions with Pd/C catalyst? A: Yes, it is designed for catalyst recovery in hydrogenation, oxidation, and other reactions. The PTFE seal is compatible with hydrogen and common solvents. Ensure that the pressure rating matches your reactor pressure.
- Q: Is the housing available with a heating jacket for hot filtration? A: Yes, a heating jacket (steam or electric) can be added as an option. Please specify when ordering.
- Q: What is the standard delivery time? A: For standard sizes (10"/20"), delivery is 15-20 working days after order confirmation. Custom sizes may take 25-30 days.
- Q: Do you offer certificates like material test report or pressure test report? A: Yes, we provide material certificates (EN 10204 3.1) and hydrostatic test reports upon request at no extra charge.
- Q: Can I use this housing with other catalyst types like Pt/C or Raney Nickel? A: Absolutely. The housing material is compatible with most catalysts. However, for Raney Nickel (pyrophoric), special precautions like inert gas blanketing are recommended – we can advise on modifications.
- Q: What is the minimum order quantity (MOQ)? A: MOQ is 1 piece for standard models. For custom designs, MOQ may be 5 pieces.
- Q: How do I clean the housing after use? A: The housing can be cleaned by flushing with suitable solvent, then rinsing with deionized water. The smooth internal surface (Ra ≤ 0.4μm) makes cleaning efficient. For stubborn residues, a CIP (clean-in-place) system can be integrated.
