• Mesh Type: Woven wire mesh, sintered mesh, or perforated metal can be used, depending on the application.
• Structure: Single-layer woven mesh, multi-spot welded for stability.
• Mesh Type: Square woven wire mesh.
• Wire Diameter: 0.1 mm to 0.5 mm
• Mesh Count: 20 mesh to 200 mesh
• Shape & Dimension: Custom shapes (sector-shaped, trapezoidal, semi-circular), dimensions vary according to customer specifications.
• Applications: Filtration in chemical, petrochemical, oil, gas, pharmaceutical, food processing, and automotive industries. Fluid filtration, air/gas filtration, or particulate separation.
• Specific Example: 6-inch (152.4 mm) diameter cartridge with a 15-inch (381 mm) height is a commonly requested size for industrial applications.
• Thickness: Thickness of the filter disc or cartridge varies depending on the number of layers and the mesh type, ranging from a few millimeters to several centimeters.

• Thickness: Stainless Steel Mesh About 0.05 mm to 0.25 mm (typically around 0.1 mm). dutch weave is usually denser and a bit thicker than plain or twill weave.
• Edge Finish: The edges can be plain cut, laser cut, or have a bound edge to stop them from fraying.

Rupture Mesh Discs (Burst Mesh Disc) for CO₂ Cylinder Valves

Rupture Mesh Discs, also known as Burst Mesh Discs, are critical safety components designed to prevent catastrophic failure of CO₂ cylinders due to over-pressurization. They act as a one-time pressure relief device. Once the pressure inside the cylinder exceeds a predetermined limit, the disc is designed to rupture (burst), safely releasing the excess pressure.  

• Material: Brass or stainless steel disc with a stainless steel mesh backing.
• Rupture Pressure: Approximately 3,000 psi (with a tolerance of ±10%).
• Outer Diameter: Commonly in the range of 8–10 mm.
• Disc Thickness: Around 0.2–0.4 mm.

• Hole Shape: Straight (implying cylindrical and perpendicular to the disc surface)
• Overall Diameter: 650 mm
• Thickness: 0.5 mm

Wire Mesh Filter Disc – Classic Design

Compact Flat Mesh Filter Disc

• Overall Dimensions: Diameter ranges from 10 mm to 150 mm. This size range fits various equipment, from small lab setups to large industrial filters.
• Thickness Dimensions: Single layer is about 0.2 mm thick. Multi-layer can be up to 1 mm or more, getting thicker with more layers and stronger wires.
• Mesh Opening Dimensions: Mesh count is 10 to 500. This means opening sizes go from a large 2000 µm (10 mesh) to a small 25 µm (500 mesh). Higher numbers mean smaller holes for finer filtering.
• Edge and Tolerance: Diameter is accurate to ±0.1 mm. This tight tolerance ensures the filter fits snugly and correctly into its housing.

Enhanced Pleated Spin Pack Filter Disc

• Outer Dimensions: Outer diameter ranges from 25 mm to 150 mm. This design suits systems needing both a small size and the ability to handle a good amount of flow.
• Pleat Design:Pleat depth is 5 mm to 20 mm. Deeper pleats mean more surface area is available for filtration. The fold count is 20 to 60 folds, with more folds allowing the filter to hold more dirt before needing to be changed.
• Overall Thickness: Thickness varies from 1 mm to 3 mm. This depends on how tightly the filter is pleated and how many layers of mesh it has.
• Surface Area Advantage: The effective filtration area is 2 to 5 times larger than a standard flat disc. This increased area allows the filter to run for a longer time before it needs cleaning or replacement.

Ring-Shaped Rimmed Extruder Screen Filter Disc

• Outer and Inner Dimensions: Outer diameter ranges from 50 mm to 200 mm, while the inner diameter spans 20 mm to 100 mm. This design is specifically made to fit circular setups in extruder systems that handle high pressure.
• Rim Dimensions: The rim width measures 3 mm to 10 mm, and its thickness is 1 mm to 3 mm. This rim adds extra strength to the disc, helping it resist bending or breaking when under pressure.
• Mesh Opening Dimensions: The mesh count varies from 20 to 400 mesh, resulting in opening sizes from a larger 1000 µm (20 mesh) to a finer 30 µm (400 mesh). This range is suitable for different levels of filtration needed in polymer and rubber processing.
• Overall Thickness: The total thickness is generally less than 5 mm. This slim design ensures that the filter disc can easily fit into filter plates and screen changers without taking up too much space.

Robust Mild Steel Extruder Screen Filter Disc

• Disc Diameter: The diameter ranges from 20 mm to 150 mm. Custom sizes can also be made for extruders with unique dimensions.
• Wire and Mesh Dimensions: Wire diameter is 0.2 mm to 0.6 mm. Thicker wires provide more strength for demanding applications. 1 The mesh count spans 10 to 80 mesh, with opening sizes from a large 2000 µm (10 mesh) to a smaller 150 µm (80 mesh). These larger openings are good for initial filtration or processing large amounts of material.  
• Thickness Dimensions: The total thickness is 0.5 mm to 2 mm. This depends on the number of mesh layers used, typically one to three.
• Shape and Tolerance: The shape is usually circular, but oval or other custom shapes are possible. The diameter tolerance is ±0.2 mm, ensuring reliable performance and simple installation.
