Cylindrical Filters
Cylindrical Filters | Stainless Steel, Sintered Mesh & Porous Metal Filter Elements Manufacturer
Cylindrical filters are precision-engineered filtration elements designed to remove solid contaminants from liquids, gases, or molten materials as they pass through a tubular filter structure. Their rigid, symmetrical shape offers uniform flow distribution, high mechanical durability, and excellent filtration efficiency even under extreme operating conditions.
These filters are typically constructed from metallic media—such as stainless steel woven wire mesh, sintered mesh laminates, perforated metal tubes, or sintered porous metal. Compared with disposable non-metallic filter elements, cylindrical metal filters deliver vastly superior resistance to temperature, pressure, corrosion, and repeated backwashing cycles. For industries requiring stable long-term performance, cylindrical filters offer a robust, cost-effective solution.
Cylindrical filters are widely adopted across polymer extrusion, petrochemical refining, catalyst recovery, gas purification, water treatment, and food and pharmaceutical processing. Their modular design, wide material selection, and unlimited dimensional customization make them suitable for almost any filtration process—particularly where reliability and consistency are mandatory.
Types of Cylindrical Filters
Cylindrical filters are available in multiple structural configurations and filtration media to meet the diverse requirements of industrial processes. Each type offers distinct advantages in terms of filtration accuracy, mechanical strength, thermal stability, and cleanability. By selecting an appropriate filter structure—such as woven wire mesh, multi-layer sintered mesh, perforated metal, pleated media, or sintered porous metal—engineers can optimize system performance, extend service life, and ensure long-term process reliability.
Wire Mesh Cylindrical Filters
Manufactured using single-layer or multi-layer stainless steel wire mesh. They provide accurate filtration ratings and are suitable for medium temperatures and moderate flow rates.
Sintered Mesh Cylindrical Filters
Made by sintering multiple layers of woven wire mesh into an integrated, rigid laminate. This option offers superior mechanical strength and precise filtration control.
Sintered Porous Metal Cylindrical Filters
Produced through metal powder sintering technology. They create a three-dimensional, fully interlinked porous structure ideal for depth filtration.
Perforated Metal Cylindrical Filters
Fabricated using stainless steel, carbon steel, or alloys with precision-drilled or punched apertures. Often used as support cores or heavy-duty filtration elements.
Pleated Cylindrical Filters
Pleated designs maximize the filtration area within the same volume, extending service life and reducing pressure drop.
Wedge Wire Cylindrical Filters
Wedge wire cylindrical filters are manufactured by wrapping and welding V-shaped profile wires onto support rods to form a rigid, non-clogging, and highly durable cylindrical structure.
Advantages of PFM SCREEN's Extruder Screens
PFM SCREEN’s cylindrical filters are engineered to deliver high-performance filtration in demanding industrial environments. Leveraging advanced mesh weaving, multi-layer sintering, precision welding, and strict quality control, our filters offer superior durability, consistency, and operational efficiency.
1. Superior Filtration Accuracy and Stability
Our cylindrical filters provide repeatable and stable filtration performance due to tightly controlled mesh specifications and uniform pore structures. Whether produced with woven stainless steel mesh, sintered mesh laminates, or porous metal materials, each filter element is manufactured to achieve precise micron ratings and consistent flow characteristics.
2. Multiple Filtration Media and Structural Options
Customers can specify mesh types (Dutch weave, square weave, sintered mesh), perforated-mesh composites, sintered porous metal, pleated elements, and wedge wire structures. This flexibility ensures that each cylindrical filter matches the exact requirements of viscosity, solids loading, temperature, chemical compatibility, and cleaning method.
3. Precision Fabrication and Custom Engineering
PFM SCREEN provides fully customized dimensions, filtration ratings, and connection types (threaded, flange, quick-opening, DOE, 226, 222, and non-standard designs). Our engineering team supports OEM orders, drawing development, reverse engineering of existing parts, and rapid prototyping for specialized equipment.
4. Consistent Quality Through Rigorous Testing
Every cylindrical filter undergoes dimensional inspection, pressure-resistance testing, material verification, porosity testing, and surface finish checks. This ensures batch-to-batch uniformity and reliable performance in critical applications such as polymer extrusion, petrochemical refining, and food-grade processes.
Applications of Cylindrical Filters
Cylindrical filters are widely used across industrial processes that require stable flow, high mechanical strength, precise particle retention, and reliable performance under thermal or chemical stress. Their robust metallic construction, uniform pore structure, and high open area make them suitable for continuous, high-load, and high-temperature filtration environments.
