Precision 1um SS Filter

Customizable Precision 1µm SS Filter: Standard 60mm OD & Multi-Length Options

Engineered for high-efficiency filtration, this element is manufactured from premium 316L stainless steel powder through high-pressure molding and vacuum sintering. The result is a rigid, self-supporting metallic structure with uniform pore distribution and exceptional dimensional stability.

Each cartridge features a seamless or precision-welded body to ensure mechanical integrity under high differential pressure. Unlike woven mesh, the sintered powder structure prevents pore migration and media shedding, ensuring a consistent 1µm​​​​​​​ rating.

Its tortuous path pore geometry provides superior depth filtration and high dirt-holding capacity. Highly resistant to corrosion and temperatures up to 600°C, it supports repeated backwashing and ultrasonic cleaning, significantly extending service life. Available in standard and custom configurations (DOE, 222, 226) to meet diverse system requirements.

Manufacturing Process

Our Precision Sintered Powder Filters undergo rigorous manufacturing steps:

• Raw Material Selection: High-purity 316L stainless steel powder inspection for optimal particle size.

• Precision Molding: Advanced isostatic pressing to ensure uniform density and controlled porosity.

• Vacuum Sintering: High-temperature bonding creates a rigid, self-supporting porous structure.

• Sizing & Shaping: Precision machining for perfect concentricity and dimensional accuracy.

• End-Cap Assembly: Professional TIG/Plasma welding for robust connection points (DOE, 222, 226).

• Quality Assurance: Strict bubble point, flow rate, and structural integrity verification.

Customization Options

We understand that every application has unique requirements:

• Custom Dimensions: Tailored lengths and diameters available to fit any housing.

• Specialty Alloys: Titanium, Hastelloy, Monel, and other high-performance materials.

• Unique Connections: Threaded (NPT/G), flanged, or custom-engineered fitting configurations.

• Graduated Porosity: Multi-grade sintered structures for enhanced dirt-holding and longer life.

• Surface Treatments: Specialized coatings and finishes for extreme chemical environments.

Sintered filter cartridges can be manufactured in a single-open-end design, with the closed bottom constructed from sintered metal mesh.

FAQ

Q: How often should I replace my Precision 1µm​​​​​​​ Sintered Filter? 

A: Replacement frequency depends on your specific process and contaminant load. We recommend monitoring Differential Pressure (ΔP); a significant increase indicates it's time for cleaning or replacement.

Q: Can these sintered powder filters be cleaned and reused? 

A: Yes. Their rigid 316L structure allows for multiple cleaning cycles via backwashing, ultrasonic treatment, or chemical CIP, significantly lowering your total cost of ownership.

Q: What is the maximum operating pressure? 

A: Standard 60mm elements typically handle up to 250 PSI (1.7 MPa). For high-pressure applications, we offer custom-reinforced designs to meet your specific PSI requirements.

Q: Are these filters suitable for food and beverage applications? 

A: Absolutely. Our 316L stainless steel construction is FDA-compliant and corrosion-resistant, making it ideal for food-grade filtration and high-temperature sterilization.
