Mesh filter model 821C, DN15 PN25, mesh opening 1 mm (45 openings/cm²). Body material: gray cast iron. Max. temperature: 350 °C 821C015D50

Mesh Filter – Reliable Protection for Installations

The mesh filter Figure 821C is an essential component in any system where medium purity is critical. The use of a stainless steel insert ensures effective removal of mechanical contaminants, protecting equipment from damage and extending its service life. The cast iron body construction guarantees strength and corrosion resistance, while the ability to operate at temperatures up to 350°C broadens its application range. This filter is suitable for both hot and cold water systems, as well as steam systems and demanding industrial processes.

Design and Application – For Installers and Users

This filter is a proven protective element against mechanical contaminants. Its construction, based on gray cast iron (grade GGG 40.3 / GJS-400-18), ensures durability and resistance to mechanical stress. The flanged connection (per EN 1092-2) simplifies installation and integration with existing infrastructure. The stainless steel insert, with a mesh density of 45 openings/cm² (1 mm aperture), effectively captures contaminants, ensuring optimal system performance. As a result, this filter performs reliably in hot and cold water systems, steam systems, and demanding industrial environments — including district heating, refrigeration, air conditioning, and power generation.

• Robust Construction: Gray cast iron body ensures long-term, reliable operation.
• Effective Filtration: Stainless steel insert with 1 mm aperture (45 openings/cm²) efficiently removes mechanical impurities.
• Wide Application Range: From residential installations to advanced industrial processes — ideal wherever contamination protection is required.
• Easy Installation: Flanged connection compliant with EN 1092-2 facilitates seamless integration into existing systems.
• High Temperature Resistance: Operational capability up to 350°C expands the filter’s application scope.
• Standards Compliance: Meets requirements of EN 12266-1; flanges are forged in accordance with EN 558-1 Series 1.

The Figure 821C mesh filter features a pressure class of PN 25, indicating its ability to operate at a nominal pressure of 25 bar. The cover is secured with bolts, allowing easy access to the filter insert for maintenance and cleaning. Regular cleaning of the filter is recommended to maintain high efficiency and ensure continuous protection of the system against damage caused by contaminants.
