As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory, established in 1998 with annual export values exceeding US$5 million, we are proud to present our Sintered Stainless Steel Powder Filter, 5 Micron, 400°C, High Pressure 30 Bar, 200mm Length. This filter element is engineered to deliver exceptional performance in demanding filtration applications where high temperature, high pressure, and fine particle retention are critical. Our decades of experience in metal wire mesh and sintered products ensure you receive a reliable, durable solution that meets the rigorous standards of global industries.
This sintered stainless steel powder filter is manufactured by compressing and sintering stainless steel powder into a porous structure, creating a uniform, rigid filter medium with excellent mechanical strength and thermal stability. The 5-micron filtration rating allows precise removal of fine particles while maintaining high flow rates. With a maximum operating temperature of 400°C and a pressure rating of 30 bar, this filter is ideal for corrosive fluids, hot gases, and high-viscosity liquids. The 200mm length offers a compact design, easily integrated into existing systems.
Key Features & Specifications
- Filtration Rating: 5 micron (absolute) – ensures high efficiency in removing fine contaminants.
- High Temperature Resistance: Up to 400°C – suitable for hot gas filtration, steam, and high-temperature chemical processes.
- High Pressure Capability: Rated for 30 bar (435 psi) – robust design for high-pressure systems without deformation.
- Material: 316L or 304 stainless steel powder – excellent corrosion resistance against acids, alkalis, and organic solvents.
- Length: 200 mm (standard) – other lengths available upon request (customizable).
- Filtration Area: Large effective area due to multi-layer sintered structure, minimizing pressure drop.
- Cleanability: Backwashable and reusable – reduces replacement costs and downtime.
- Reinforcement Options: Stainless steel support mesh or perforated core for added strength (optional).

Detailed Product Advantages
The sintered structure provides a uniform pore distribution, resulting in consistent filtration performance and high dirt-holding capacity. Unlike woven mesh filters, powder filters offer deeper filtration, capturing particles within the matrix. This design also allows for easy cleaning through backwashing or ultrasonic methods, extending the service life significantly. The high-temperature resistance makes it suitable for gas filtration in petrochemical reactors, exhaust gas treatment, and high-temperature liquid filtration. The 30-bar pressure rating ensures reliable operation in hydraulic systems, polymer filtration, and high-pressure chemical injections.
Customer Benefits: Reduced maintenance costs due to reusability, improved product quality through precise particle removal, and system reliability under extreme conditions. The compact 200mm length enables easy installation in space-constrained equipment. Additionally, we offer customization of outer diameter, end connections, and additional reinforcement layers to match your specific requirements.

Frequently Asked Questions
- What is the difference between 5 micron nominal and absolute? Our filters are typically rated as absolute, meaning they capture 98%+ of particles of that size. We can provide bubble point test data upon request.
- Can this filter be cleaned and reused? Yes, the sintered metal structure allows backwashing with clean fluid or ultrasonic cleaning, restoring most of the original flow capacity.
- What are the available outer diameters? We offer standard diameters from 20 mm to 100 mm, and custom sizes are available. Please specify your required OD.
- Is the filter suitable for food & beverage applications? Yes, the 316L stainless steel material is FDA-compliant (upon request) and can be used for food-grade filtration.
- What is the maximum pressure at 400°C? The pressure rating decreases at elevated temperatures; please consult our technical team for derating curves for your specific application.
- Do you provide samples for testing? Yes, we can provide small samples for evaluation. Contact us for sample availability and lead time.
- What end connections are available? Standard options include NPT threads, BSP threads, and flanges (ANSI, DIN). Custom end caps are also possible.
- How long is the typical lead time? For standard sizes, lead time is 10–15 working days. Custom orders may require 20–25 days depending on complexity.
