Reliable Porous Metal Filters For Industrial Applications
We manufacture Porous Metal Filter products, including sintered filter elements, porous stainless steel tubes, and filter discs. If you’ve dealt with filters that clog fast or lose shape under harsh conditions, you know how frustrating that gets. We control powder particle size and sintering temperature closely, so every filter we produce holds a consistent pore structure that keeps performing over time. Whether you’re filtering gas, separating solids from liquids, or working with high-purity media, tell us your operating conditions and we’ll help you find the right match.
Our Products
Formed from sintered metal particles, 35%-80% porosity, low flow resistance, high dirt-holding capacity.
Isostatically pressed for uniform wall thickness, stable under high flow, high pressure, and high heat.
Flat structure, easy to install, ideal for gas diffusion and final-stage filtration, custom sizing available.
Pore sizes from 0.2 to 200 microns, matched precisely to the particle size you need to capture.
Our Advantages
0.2–200 μm pore sizes with tight tolerances
Consistent pore structures help deliver predictable filtration performance across every batch.
Up to 80% porosity for efficient flow
High open porosity helps reduce pressure drop and maintain efficient fluid or gas flow.
316L stainless steel for demanding media
Suitable for corrosive fluids, gases, and challenging industrial environments.
Stable performance under high temperatures
Maintains structural integrity and filtration performance in high-temperature applications.
Easy to clean and restore flow performance
Backwashing helps extend service life and reduce filter replacement frequency.
Resists pressure, vibration, and demanding operating conditions
The sintered metal structure provides reliable mechanical stability during operation.
Easy to integrate into existing filtration systems
Can be customized with different shapes, connections, and configurations to match your equipment.
Standard sizes available; custom samples in as little as 7 days
Lianda supports both standard products and customized Porous Metal Filter solutions.
Why Choose Lianda Porous Metal Filters For Consistent Performance
Filtration performance should not decline after only a few operating cycles. Lianda Porous Metal Filters are manufactured with carefully controlled powder particle sizes and sintering parameters to create a stable, uniform pore structure. This helps maintain consistent filtration performance, flow rates, and mechanical strength throughout service. When contaminants build up, many of our filters can be cleaned by backwashing and returned to service, helping reduce replacement frequency and long-term operating costs.
Why Choose Lianda For Porous Metal Filters?
Lianda controls every critical step behind reliable Porous Metal Filters—from material selection to final inspection. We select materials such as 316L stainless steel, bronze, titanium, and nickel alloys according to your operating temperature, pressure, corrosion conditions, and filtration requirements. During production, we carefully control powder particle size, compaction, sintering temperature profiles, and pore structure to ensure consistent filtration performance. Each filter is then inspected for dimensions, permeability, and quality before shipment.
Customer Reviews
Lianda provided us with customized Porous Metal Filters for our high-temperature filtration system. The pore structure is consistent, the product quality is stable, and the filters continue to perform well under demanding operating conditions. Their technical team also helped us select the right material and specifications for our application.
Michael RWe were looking for a supplier that could provide durable porous metal filter elements with strict quality control. Lianda delivered filters with accurate dimensions and reliable filtration performance. Their fast response and customization capability made the entire sourcing process much easier.
David KAfter testing several suppliers, we chose Lianda because of their controlled manufacturing process and consistent product quality. Their porous metal filters offer good mechanical strength, easy maintenance, and long service life in our applications

Standard mesh filters are typically woven or perforated, which limits pore uniformity. A Porous Metal Filter is sintered from metal powder, giving it a more consistent pore structure, higher strength, and better heat resistance.
We keep standard sizes in stock and also accept small-batch custom orders. Reach out with your quantity and we can usually work something out.
These filters are designed to trap and remove particulate matter from gases and liquids, offering high durability, excellent resistance to high temperatures and corrosive environments, and the ability to withstand differential pressures.
Porous metal filters are manufactured by precompressing and heating to sintering temperature spherical, uniformly sized stainless-steel particles. The filters are available in pore sizes from 0.1 to and in several thicknesses and diameters.
