Mesh filter model 821C, DN100 PN25, mesh opening 1.6 mm (15 openings/cm²). Body material: gray cast iron. Max. temperature: 350 °C 821C100D43

Mesh Filter for System Protection

The mesh filter type 821C is a reliable protective component designed to safeguard installations against mechanical contaminants. Manufactured from high-quality gray cast iron, it ensures durability and corrosion resistance. Suitable for use in hot and cold water systems, steam lines, and a wide range of industrial applications—from district heating and refrigeration to power generation. Its design allows for easy cleaning of the filter without requiring disassembly from the system, minimizing downtime and reducing operational costs.

Construction and Application

The filter features a compact design with a stainless steel insert, ensuring effective trapping of contaminants. Thanks to its flanged connection (compliant with EN 1092-2) and drilled flanges, installation is fast and straightforward. The filter meets the requirements of EN-12266-1, confirming its safety and reliability. The installation length complies with EN 558-1 Series 1, facilitating seamless integration into existing systems.

• Mesh opening: 1.6 mm (15 openings/cm²) – ensures optimal filtration for the type of contaminants expected.
• Body material: Gray cast iron (GGG 40.3 / GJS-400-18) – guarantees strength and resistance to mechanical damage.
• Maximum operating temperature: up to 350°C – enables use in demanding thermal conditions.
• Pressure class: PN 25 – ensures safe operation in systems with elevated pressure.
• Nominal diameter: DN100 – matched to medium-capacity installations.

This filter is suitable not only for residential and public buildings but also for industrial applications where medium purity is critical for the proper functioning of equipment and technological processes. Notably, this filter is available in various material constructions (gray cast iron, ductile iron, carbon steel, stainless steel) and pressure classes (6, 16, 25, 40 bar), allowing precise adaptation to the specific requirements of each installation.
